Larson Electronics 300 Watt LED High Bay Light Fixture - 120-277VAC - 1000W Metal Halide Equivalent - 29,580 Lumens

Buy American Compliant The GAU-HB-60X5W-1227 High Output LED High Bay Light offers high output and energy efficient alternative to traditional general area luminaries. LED technology and compact design makes this lamp an excellent energy efficient upgrade option for bulky and high maintenance cost older fixtures. A 29,580 lumen output, 2.5 amp draw, 50,000 hour service life, and 120-277 volt compatibility provides mine operators with a rugged and powerful LED alternative to 1000 watt metal halide lamps that uses little power and can withstand rugged use and abusive conditions. The GAU-HB-60X5W-1227 LED high bay light from Larson Electronics produces 29,580 lumens of high intensity light while drawing only 300 watts @2.5 amps from a 120 volt electrical system. Sixty CREE XLamp XPG¨ five watt LEDs producing 493 lumens each are arranged in rows and paired with high purity optics to produce a well focused 25 degree spot beam that is ideal for providing far reaching concentrated illumination while still covering a substantial amount of area. We also offer optional floodlight versions with a 60 degree beam spread to provide more light over a larger area nearer the fixture, making flood versions ideal for use as dedicated work and area lights. These LED light bars are waterproof to 3 meters, sealed against intrusion by dust and dirt, and very ruggedly constructed to withstand the most demanding mining environments, conditions and applications. GAU-HB-60X5W-1227 LED lights are ideal replacements for fragile and hot running 1000 watt metal halide lamps. They offer Pulse Width Modulation control, a small profile, low power requirements, high durability and a versatile mounting system that makes these LED light emitters a superior lighting solution for mining applications where power and reliability is critical. The heavy duty design and high power of these mining lights also makes them suitable for a wide array of applications including but not limited to: military, industrial manufacturing, machine visioning, security and law enforcement, and commercial structure illumination. Heat Management: Heat is the single largest factor in premature LED failure and color shifting. These LED units contain advanced drivers which use pulse width modulation to control heat buildup rather than simple voltage regulators which are typically harsh on sensitive electronics and can contribute to early LED failure. These units automatically sense the temperature of each LED and adjust the energy frequency or “duty cycle” accordingly to maintain heat levels within acceptable ranges. This system in essence flashes current at an extremely fast on and off rate to each LED based upon the LED’s core temperature. This flash rate is too fast to detect with the human eye, but provides precise control of the current flowing to each LED and thus the heat it generates. This allows the LEDs to be driven at up to 90% capacity without overheating or visible loss of light output. The LEDs are always driven at the same voltage but the duty cycle, however, is changed to alter how long the LEDs are actually on or off. The end result is more light with less heat and longer LED life with an average 70% lumen maintenance after 50,000 hours. PWM Control: The pulse width modulation drivers in this unit also provide secondary benefits through the ability to automatically monitor and adjust input current to maintain the correct LED voltage levels regardless of input levels across a specific range. These GAU-HB-60X5W-1227 high bay lights can operate on current ranging from 120 to 277VAC without any modifications necessary as a result. This ability to sense and adjust input current also provides protection against voltage spikes and drops that can occur in vehicle electrical systems which would otherwise result in burning up or premature LED failure without it. Durability: As well as unparalleled heat control, the GAU-HB-60X5W-1227 series of LED high bay lights from Larson Electronics also offer IP68 rated construction that is designed to withstand extremes of environmental and operating conditions. These units can withstand rapid temperature changes of -40 degrees Celsius to 80 degrees Celsius, are waterproof to three meters, and resist ingress of dust, dirt and humidity. The housings are formed from extruded aluminum and the lenses are unbreakable polycarbonate. The CREE XLamp XPG¨ LEDs help these units achieve 15.6Grms rated resistance to vibrations and are rated at 70% lumen maintenance after 50,0000 hours of use. We recommend these LED lights for use in applications where a lot of vibration, dust, dirt, dampness and abusive working conditions are encountered. Mounting: Each unit is equipped with an innovative trunnion style mounting bracket that allows the light to be attached to flat surfaces and adjusted through 360 degrees of vertical movement. To adjust the unit after mounting, the user simply loosens the thumb screws located on either side of the unit, moves it into the desired position, then retightens the screws. The base of the mounting trunnion is equipped with several machined slots which allow users to utilize existing mounting holes and slide the unit for precise mount positioning.
