Learn Everything About Lighting

What is an LED light?

Stands for light-emitting diode. LED light bulbs and fixtures have taken the main spotlight day to day.

LEDs have small semiconductor electronic components, or diodes. LED works sending energy through conductors material. Then, diodes emit electromagnetic radiation that generates the device lighting.

LEDs have a low temperature light, thus being more safe. Also reduce electrical consumption and improve efficiency. 

What is an OLED?

OLED is an abbreviation for Organic Light Emitting Diode. The organic part refers to the carbon film that sits inside the panel, before the glass screen. 

They way OLED panels work, they emit their own light when electric current passes through. One of their biggest benefits is the ability to produce perfect black colors, giving it an infinite capacity of contrast as impossible as the claim sounds. 

oLEDS are used for creation of digital displays seen in computer monitors, handheld game consoles, television screens and smartphones. Biggest drawbacks are pricing, but onwards as the technology develops that could change.

What is an Incandescent and a Halogen bulb?

Incandescent and halogen are often paired up because of how they function . Both heat up a tungsten filament and have a bulb filled with gas.  Both of these bulbs produce lightning through an "incandescent" effect.

Difference is, halogen has inert gas and a small amount of halogen  (bromine and iodine.) This produces a halogen cycle,  a chemical reaction that prolongs the filament life use and allow higher temperatures, thus brighter light with same efficiency (even more)

Despite their huge use through many years and decades, nowadays they are replaced by more efficient lighting like CFL or LED bulbs.

What is neon lighting? 

Usually seen in signs, advertising and now in computer components such as GPUs, this type of lighting uses electrified glass tubes or bulbs that contain a small amount of rarified neon or other gases.

Neon light works using electrical current that when contacting the gas, produces a reaction that causes the lighting. 

Main benefits of neon lights are long lifespan (5-10 years), energy efficiency, customizable shapes and high visibility.

Other uses of neon lights besides advertising are Bar signs for example, car ignition lights and high intensity lamps. 

What is UV lighting?

UV lighting has gained a lot of popularity through the use of UV-C lamp types with their germicide power. Ultraviolet Light is one of the electromagnetic radiation that makes black-light posters glow.

The wavelengths of UV are shorter than those of visible light and longer than those of X-rays.  In terms of lighting to let you see things, UV radiation starts at the violet side of the rainbow, this means that UV lights cannot be seen.

The electromagnetic radiation comes from the sun and is transmitted in waves or particles at different frequencies and lengths. All the ranges are included in the Electromagnetic Spectrum. Common designations: radio waves,microwaves, infrared (IR), visible light, ultraviolet (UV), X-rays and gamma-rays.

UV Lighting is used in many areas, such as Horticulture, Germicide and Disinfectant spaces in Health areas, in Tanning equipment…all will depend on the type of UV.

There are three types of bulbs. Blacklight Blue (BLB), Blacklight (BL368), and Germicidal 

What is fluorescent lighting?

Lighting that its main source comes from the use of fluorescent lamps and CFL (Compact Fluorescent Lamp).

Fluorescent light works with gas filled bulbs with electrodes at both ends. Collision of electrical current makes the mercury atoms in the gas get excited, this reaction makes the atoms emit visible and Ultraviolet light. To expand this UV light illuminates a phosphor coating which emits “fluorescent light”. 

To understand this process better there are two great educational videos explaining this.

Fluorescent lighting has an immense presence in the United States through schools, hospitals, grocery stores, office buildings, our homes, etc. Despite being very popular, they’re slowly being replaced as the favorite green lighting option against LEDs. 

What is a CFL?

Stands for Compact Fluorescent Light, this bulb was designed to replace an incandescent light bulb and a means to make fluorescent light more accessible for homes.

The lamps use a tube that is curved or folded to fit into the space of an incandescent bulb, and a compact electronic ballast in the base of the lamp. 

Some types fit into light fixtures designed for incandescent bulbs. Their benefit over incandescent bulbs is that  they are more energy-efficient, also they can fit into a lot of old fixtures, making them an easy replacement. 

What is a HID? What are the different types?

Stands for High-intensity discharge Lamp. These function through an arc effect of discharging a gas. HID lamps have arc tubes, require a ballast, all of them strike an arc through, and produce a lot of heat. 

HID Lamps due to their intensity and power are often used in commercial settings and in big spaces.  For example: Sport Stadiums , Highways, Parking lots, Roadways, etc. 

There’s different types of HID. Metal Halide (MH), Mercury Vapor (MV) and High Pressure Sodium (HPS). 

The main difference to tell them apart are in the most recognizable way, the colour or type of light they produce. Metal Halide creates a Bright White, Mercury Vapor an Fluorescent White and High Pressure Sodium an Orange one.

More in-depth is their inert gas, Mercury in MV, use of halides salt on MH and Sodium on HPS. As base gas MH and MV use Argon, HPS lamps use Xenon instead. 

What are the different shapes of bulbs? 

In all lighting history there were developed many types of bulbs and shapes as lighting technology advanced. To keep it simple we're gonna share a list with some of the modern types of  shapes of bulbs so you can guide yourself.  

  1. Standard Household – denoted with an A
  2. Candle – denoted with a C
  3. Reflector – denoted with an R
  4. Mini Reflector – denoted with MR
  5. Parabolic Aluminized Reflector – denoted with PAR
  6. Globe – denoted with G
  7. Tubular – denoted with a T

When buying a Bulb you’re gonna notice first the letter or acronym that identifies the type of shape, this is accompanied by a number that states the size of the bulb. For example an A19, the most common type of bulb, has an A for Arbitrary and 19 for its size, 19/8 inches in size.

This is a graphic from GreenLivingIdeas that illustrates the shape of bulbs and variants. 

What is CCT? 

Stands for Correlated Color Temperature. When we talk about temperature in lighting, we refer to the grade of colour, gauging how yellow or blue is the color of light emitted from a bulb. 

This is measured by Kelvin, most light is between 2200 Kelvin degrees and 6500 Kelvin degrees. 

Another way to describe it is that Colour temperature measures the color produced by the heat of metal objects. According to the heat temperature, colors will vary between orange, yellow and blue.

What is beam angle?

Is the light distribution that comes out of a bulb directed to an object. The bigger the distance from the object the smaller angle it’s necessary for the light to illuminate the object. 

The beam spread you need will depend on the use you want to give to the lamp. More often than not when you use a smaller beam angle it means you want to accent a decor element or something that needs to draw attention. 

These are on the most common beam spread angles:

  • 15 to 30°: This is mostly for accent something, a detail or an object,
  • 35 to 55°: Punctual zones, focusing luminosity on that area.
  • 60° to 110°: For broad spaces and reduces shadows.
  • 120° onwards: Uses for general lighting, functions to dissipate any shadow and light the most space possible.

What is a retrofit? 

A retrofit is to turn existing objects, items, or devices into ones that support new features or technologies. In lighting refers to exchanging commercial or domestic lighting fixtures usually to enable LED bulbs. 

Using LEDs comes with huge benefits, better light quality, efficiency, and less maintenance.

Doing a Retrofit requires some thought. Upfront costs vary between a few thousand to hundreds. So it's important to trust specialized companies for Retrofit,  which can save you tons in the long run. 

What is a ballast?

Ballast in a fluorescent light has the function to regulate the current to the lamps, making sure enough voltage is given to start the lamp.

Without a ballast, a fluorescent lamp would be unstable and shorten their lifespan.

Ballast works in the start of the lamp by supplying high voltage for a brief moment. After the lamp is lit it immediately regulates the current to produce a steady light output. 

One important thing to keep in mind is that ballast efficiency would depend on the type of luminaire and specifications of it, so be sure to pick one that adapts to yours. 

What is an IP rating?

The acronym stands for Ingress Protection, the IP rating is used to classify the degree of protection provided by an enclosure, for electrical equipment with a rated voltage not exceeding 72.5 kV.

They are used to define levels of sealing effectiveness of . IP ratings are defined by the international standard EN 60529 (British Standard BS EN 60529:1992)

electrical enclosures against intrusion from foreign bodies (tools, dirt etc) and moisture.


This standard defines levels of sealing effectiveness against “ingress” i.e. intrusion from foreign bodies such as tools, dirt and liquid water.

These are divided by their digits, first digit it’s about solids or instrussion protection, there are seven levels. The first being no protection to the seven being totally dust tight, one recommended for harsh conditions of work is 6, that is partial protection against dust that could harm the equipment.


Second digit is about liquids or moisture protection. First level being no protection to 11 Protection against high-pressure, high-temperature jet sprays, wash-downs or steam-cleaning procedures. Recommended ones from this start from 5. Protected against spray up to 60° from vertical.

Depending on your branch of work, understanding IP ratings are important to ensure security for you, your workers or your equipment. 

What is an EPA rating?

Stands for Effective Projected Area. These are used to measure the wind resistance of a fixture or particular luminaire. This means that when you install a fixture, their particular EPA rating will tell you how much force of the wind they can withstand without falling.

These are an important point when installing outdoor light fixtures. The EPA, when used in combination with the luminaires coefficient of drag, relates to the force a particular fixture will impose on the pole it is mounted on when it comes into contact with the wind.

EPA helps determine the structural capacity of outdoor light poles to withstand wind forces due to the torque created by the lighting fixture sitting on top of them. It is important to understand in order to prevent the pole from failing when the environment is excessively windy.

What is Solar Lighting?

An independent lighting system that's installed in areas where photovoltaic energy works. 

Usually, Solar lighting devices store energy on batteries to provide clean energy for night lighting systems.  But the way it stores energy will also depend on the type of Solar Light system.

The amount of received energy will depend to a large degree on the sunbeam angle of arrival and intensity of it. The main drawback of these devices is that they don't work if sunlight levels are very low.

Is there a difference between indoor and outdoor light bulbs?

Yes, outdoor bulbs tend to have UL ratings that let them be used on more different types of conditions. Yet, a lot of indoor bulbs and outdoor bulbs share these specifications so it will depend on what type of use you want for them. 

For example, some indoor bulbs cannot withstand rough changes of temperature. But, what you’ll need to be paying attention to is to check out their UL rating. These are tests of certification made by Underwriters Laboratories (UL).

Below are the different locations and with the corresponding UL rating: 

  1. UL Listed- Dry Locations: labeled: “UL Listed”. includes living rooms, dining rooms, bedrooms, hallways, kitchens
  2. UL Listed- Damp Locations: “Suitable for Damp Locations” or “Suitable for Wet Locations”. includes bathtubs, showers, indoor pool areas.
  3. UL Listed- Wet Locations: labeled “Suitable for Wet Locations''. These are used in both wet indoor and outdoor locations, including gazebos, walkways, open patios and decks, and outdoor dining areas.  

What is RGB?

Stands for Red, Green and Blue, three primary colours of the additive colour system. With advances in LED technology, RGB lights grow in popularity every single day.

RGB combinations produce up to 16 millions hues of light. They achieve this by adjusting the brightness of colours. 

RGB has several uses, from parties, decor, to signs, advertising, computer lights, children rooms, plays. What makes them so popular is their versatility that fits pretty much in every place. 

What is Voltage?

We can define the voltage as the amount of potential energy between two points in a circuit.The voltage or potential difference gives the force to the electrons to flow through the circuit.

The higher the voltage, the greater the force, and hence the more electrons flowing through the circuit. Without voltage or potential difference, electrons would move randomly in free space.

Knowing voltage is important for your electronic devices, most of them come with a little note with a V along with a number, this is the number of voltage that device uses or oscillates. Keep in mind this number with other electric knowledge and take better care of your devices. 

What is forward voltage?

Forward is the amount of voltage needed to get current to flow across a diode. LEDS has a difference between other types of bulbs, for a diode to work it needs a certain amount of voltage to go through and then needs regulation due their low voltage needs.  

This is important to know because if you are trying to get a signal through a diode that is less than the forward voltage, you will be disappointed. 

As temperature increases, the forward voltage of the LED decreases, causing the LED to draw more current. The LED will continue to get hotter and draw more current until the LED burns itself out. For this reason LEDs are more efficient in cold temperatures.

What's the difference between AC and DC power?

In Electricity there are two types of current, these are Alternating Current (AC)  and Direct Current (DC). Both are essential to power up our house's devices and all electronics.But first to point out their differences is necessary to define them.

  • Alternate Current (AC): It’s  defined by flow of charge that exhibits a periodic change in direction.  The wave changes direction having intervals or cycles. 
  • Direct Current (DC): As its name suggests this is direct, the current flows in only one direction, in a linear way. 

For everyday users, AC is the one used in all of our homes, because it’s more efficient to translate due their wave motion, it’s better at traveling distances, something useful for utility companies.

DC in exchange draws more power and the voltage they bring is more optimal, so most electronic devices use DC.

Their main difference it’s on their uses and the way they transmit  electrical current. Even though AC is the standard electricity in all homes, DC is used more in most devices due consistency in voltage delivery. A lot of electronic devices use adaptors to make AC into DC thus being more efficient.   

What is 0-10v dimming vs. line voltage dimming?

These mainly differentiate themselves by how they use voltage. Line Voltage Dimming or Voltage Dimming regulates line voltage directly usually 120v in our households. In exchange,  0-10v dimming uses a ballast that includes additional low voltage wiring; it functions by adjusting the light output based on the low voltage signals received.

Line Voltage and 0-10v dimming serve different purposes. Line voltage dimming is intended to be used on incandescent bulbs due how they are easy to dim because they produce light by way of electrical current.  Voltage dimming refers to changing the amount of current (or voltage) running to the lamp

Using line voltage dimming in incandescent bulbs is great because:

      Reduces consumption of electricity, hence helping your electrical bills.

      Increases durability of incandescent bulbs, reducing costs of replacements on this system.

      Has great dimming accuracy, ranges from 0-100 are pretty accurate due to how incandescent bulbs work.


The drawback of this dimming system is that in low voltage settings and more efficient systems adjusting line voltage output doesn’t produce good results on dimming. CFL (ones made for dimming) ranges are lower roughly 10% to 40% before they shut off completely, and doesn’t work well with LEDs either.

Now on 0-10v dimming, is actually one of the simplest and earliest electronic lighting control systems. 

The 0-10V dimming is a DC voltage that varies between zero and 10 volts, hence the name. This means that the dimmer-controlled light would be at its highest light output of 100% at 10V and at its lowest possible dimming level at zero. One factor to consider when thinking about using a 0-10V dimmer for specific applications is that most of them offer built-in line voltage relay or external line voltage relay.

The downside to this type of dimming is that the dimmer range of the power supply is limited. This means that if a light can only be dimmed to 10%, a switch or relay must be available to cut power to the system and turn the light off completely. Unlike incandescent or halogen light dimming, fluorescent lights do not dim to ‘off’, and depending on the ballast, the minimum level of light output could be in the 1% – 20% range.

An upside to using a 0-10V dimmer, especially for LED lighting is that the transition through the dimming range is smoother and lower than other dimming options. This means that as you are dimming the light, you won’t see jumps in the brightness as you might with other dimmer options.

In conclusion, using one or another will entirely depend on what system you use, both have pros and cons. Are you using incandescent bulbs? Use line voltage dimming, will improve the life time of your bulbs and reduce electrical consumption. Do you use LEDs or CFLs? Then 0-10v dimming will help you on those systems. 

What is a Conduit? 

A conduit is a natural or artificial channel through which something is conveyed. Like a channel, usually in lighting refers to metal conduits. Metal conduits are made of steel round tubes, these are often used for running cables when they cannot be hidden behind a wall.

Using Conduits in lighting has several benefits. In industry factories, where security of wiring is a must, conduits provide a safe measure for all the electrical wirings for the lights.

Nowadays, conduit is still used in some factories but has gained popularity as a lighting trend for homes, for its vintage style, something that has its place in fashion and modern decors.

What is a LED Driver?

As it sounds, it drives power to the LEDs. Is an electrical device that its main function is to regulate the power that passes through an LED or string of LEDs. In a LED system they are very important, their function is to provide current  to the LEDs itself and circuits while protecting fluctuations of voltage that can possibly damage the system.

LEDs as efficient lights require low levels of energy, they use DC and need around 1,5 to 3,5 volt and current up to a maximum of 30mA. The domestic bulbs consist of several bulbs in series and parallel combinations which requires a total voltage between 12 and 24 V DC. These drivers make sure numbers are stable to ensure not only security but efficiency for your LED system.

There are two types of LED drivers, constant voltage and constant current. Make sure your LED lamp or system has the appropriate driver to use your LEDs to the fullest.

What is a Transformer?

It’s used to convert current to another one usually lower, for example from 120 v to 12v in the case of landscape lighting.  It’s a power supply for LED lighting systems,  unlike drivers these are meant to work with higher output wattage, due this LED transformer can power larger, longer lighting systems. 

For bigger LED systems the drivers sometimes aren't enough, in those instances the transformer ensures better efficiency and provides better results. Circuitry within a LED transformer is essential to prevent premature failure of lighting systems, this helps avoid risks of fire or electrical shorts within longer systems.  

What is the ballast factor? 

A ballast factor is a number, typically between 0.70 and 1.2, that tells you how much light a lamp will emit with that ballast.

Ballast factor is calculated by dividing the lumen output of a lamp-ballast combination by the lumen output of the same lamp(s) on a reference ballast. A ballast factor of 1 means it will produce more light.

This means for example. A 0.7 ballast factor in a lamp that produces for example 1000 lumens, it will emit 700 lumens, thus in some instances is best to produce less lumens and it reduces energy costs.

There are three type of Ballast factors:

  1. Low Ballast factor .70-80 :  These ballasts save energy but produce less light. It is best suited for retrofit applications or in areas with less crucial visual tasks, like aisles, hallways and computer rooms.
  2. Normal Ballast Factor: .85-1.00 These are considered the industry light standard. They are best used in regular office, residential or commercial settings.
  3. High Ballast Factor 1.01-1.20: Create greater lumen output and therefore brighter light. Used in areas that require more light like studios, warehouses and manufacturing facilities.

What is DOB, D.O.B., or Driver on board?

Stands for Driver-on-board. Normally in LED technologies the driver is separated from the assembly with D.O.B  this is not necessary, the driver itself is on the board.

To do this D.O.B only uses solid state drivers components which are available in surface-mount packages, these are capable of being assembled in circuit boards with a single-sided copper construction. This allows them to mount driver components on metal-core printed circuit boards (MCPCB) where LEDs are mounted.


About the driver, these are designed often as a linear power supply; these reduces components due to not having electromagnetic interference (EMI). The driver current is regulated by small driver ICs without using electrolytic capacitors.


Although this technology has its drawbacks, linear supplies reduce costs but are inherently inefficient. The headroom voltage is dissipated as heat which introduces an additional thermal load to the co-located LEDs. Absence of flicker is important for any lighting system but can be challenging to DOB lighting systems because of the presence of large ripples in the DC current provided to LEDs. This imposes a risk on this type of setup. 

What is an ELV Dimmer?

ELV stands for Electronic Low Voltage. An ELV dimmer is known by a number of names. ELV dimmers are also called simply electronic dimmers, as well as trailing edge dimmers. These names come from the way in which this dimmer transitions your LEDs luminosity.

The way ELV dimmers work is that it will create a  reverse-phase, or “trailing edge” waveform. This means that it will chop the end of the AC (Alternate Current) wave. The brightness of a given light source hooked into an ELV dimmer is determined by how much “on'' time in relation to how much “off” time is applied to a given dimming situation.

ELV dimmers are often used with LED drivers because they have a great track record for improving an LED’s ability to conserve energy while providing luminosity in a functional, sustainable way.

Why Does My Incandescent Light Bulb Hum? 

There are several reasons why an incandescent  light bulb hums or produces this buzz type sound, but usually the main culprit is related to inconsistency in voltage delivery, this can be caused by dimmers.

Many dimmers work by oscillating between applying and denying voltage to the bulb at a certain speed faster than the human eye can detect, which makes the bulbs appear dimmer in a room. However, this continuous on/off cycle may cause the filaments in the bulb to vibrate, which produces a sound like a humming or buzzing. 

The vibration comes from minute heating and cooling of the metal filament, which causes a minor but very quick expansion and contraction of the material. The rattling noise is the filament against itself or against other components of the bulb.

If this is the case, the first thing you may try is replacing the bulb with a new one. Over time, the constant flickering of voltage can wear out the filaments and other components in the bulb, and replacing it can resolve this issue.  

Why is my light bulb flickering? 

A light bulb flickering can be a sign of concern or just a simple issue with a bulb, but it's something to act on or can cause damage when it’s more serious. First, there are many reasons why a light is flickering, these are the four most common reasons:

  1. Problem with bulb (not in tight enough, wrong bulb type for dimmer switch)
  2. Loose light plug
  3. Faulty or fixture switch
  4. Appliance pulling large amounts of current on startup, causing a voltage drop.

Every one of these requires different approaches. You can’t compare an issue when it’s  only related to the bulb than, for example, an overloaded circuit. 

In the case of a bulb, maybe it’s not tight enough, retightening would be the first step. Another is that you have a bulb not compatible with a dimmer switch. LEDs, as efficient and great they are, function differently to other types of bulbs so installing these on an old dimmer switch can create issues. In those instances ensure that the dimmer switch is compatible or switch your bulbs to compatible ones.

Loose light plugs or wirings are another cause of flickering, in these instances you should check the fixture and see if they’re not tight enough or are faulty, these time procedures can be made by you but in case of doubt communicate with an electrician.

Faulty or fixture switch. Good fixtures are reliable even for decades, but all electronic devices or installations can suffer damage through time, in those cases replacing it’s the solution, not only for your fixture life but also for your bulbs and installations.

That last point is appliance, sometimes lighting installations share space in a circuit with heavy drivers of current as A/C or furnaces, so when these are turned on cause a flickering. The solution for these is separating the lighting for these overloaded circuits and dedicating one for lights. 

There’s more into flickering, many details and ways to troubleshoot these issues, but this is to give you an general idea. 

How does a ballast impact my lighting?

Ballast impacts your lighting in many ways as they’re a fundamental part of several lighting systems. Ballasts work as regulators of voltage and sometimes helpers to even power up the system, that's the case of  HID Lamps, they need a ballast to function properly, ones that can withstand their high voltage requirements and also work with their ignition mechanism .

In LEDs ballast helps the system to work properly, due to low wattage of these systems, ballast adapts to these requirements so ballast impacts in regulating current and even dictating how much light output the bulbs is gonna be and consumption if you take into account the ballast factor.

So before installing a system a good rule of thumb is checking their ballast specifications to determine how the bulb is gonna function, also comparing ballast specifications with fixtures and lighting systems, will improve your lighting and help with your plans. 

Does Temperature and/or Humidity Impact Light Bulb Performance?

Yes, they do affect. How do they do it? Depending on technology, some high-wattage compact fluorescent lamps will be affected by lamp operation in cold or hot environments. 

Temperature impacts both short-term and long term performance, for instance in colder temperatures, the ignite effect to power fluorescent lights needs higher draw output. In Short term, only affects light output of HW-CFL, electric power and luminous efficiency. Over long term periods will shorten ballast life thereby making the lamp life reduce also.

In other cases, LEDs are different in how temperature affects them. For example, LEDs can benefit from colder temperatures making the lights brighter, but struggling in higher temperatures with higher current, in these cases the light output diminishes including life of the system.

Now about humidity,  fluorescent lamps can cause corrosion of the metal fixtures disabling their electricity transmit capabilities, also excess build up condensation makes it hard for the light to turn on.

In the case of LEDs it is not that serious but it will deteriorate the technology, so it's best to avoid humidity in every instance.

So in short, yes they do both affect light bulb performance but how the affect will depend on the technology of the bulb itself. 

Why is my LED dimming down and then completely shutting off? 

There may be several reasons for this to happen. But before blaming it all on the bulb you need to first check if your LED is dimmable or the Dimmer switch is compatible with your bulbs, in case they don't. Maybe it's on the Dimmer  switch and you need to replace your LED, or simply buy a bulb that works with your switch. 

After you check those, what can be the cause of your issue may be one of these common issues. Voltage fluctuations that make the LED inestable, this will cause your LED to be erratic and sometimes shutting off or on.

Another case is heat build up, LEDs reported to only support temperatures lower than 100°, so a heated up LED can dim down until completely shuts off, the good news is that most of the time if temperatures are right it will turn on again.

Appliances and overloaded circuits can affect LEDs too. If suddenly an A/C is turned on and your LEDs start to fail it may be due to overload of current, in those instances dedicating a circuit just for lighting solves it, although it can be expensive.

A lot of cases are left to be included, but selection of these ones is to give you an idea of what can cause this issue, check these articles to find out more about causes and how to solve them.

Do I need a special dimmer for LEDs?

Yes and no, will depend on your dimmer switch and your LEDs bulbs. Some LED lamps will require a type of Dimmer Switch and others can fit perfectly well in some older systems. So it will depend on checking out your LEDs specifications and dimming capabilities, after checking those you can see if your LEDs can be installed in your system.

But do remember, always check with manufacturers, consulting lighting companies or electricians to help you out with it. Lastly, keep in mind, as LEDs consume less energy, older systems aren’t going to regulate so don’t expect total accuracy in range of dim, it’s always better to install Dimmer switches tailored for Dimmable LED bulbs.
