Larson Electronics offers 150 Watt LED high bay light fixture
click image to zoom The GAU-HB-30X5W-1227 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 14,790 lumen output, 1.25 amp draw @ 120V, 50,000 hour service life, and 120 to 277 volt AC compatibility provides operators with a rugged and powerful LED alternative to 400 watt metal halide lamps that uses little power and can withstand rugged use and abusive conditions.
The GAU-HB-30X5W-1227 LED high bay light is anideal replacement for fragile and hot running 400 watt metal halide lamps. They offer Pulse Width Modulation dimming 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 industrial applications where power and reliability is critical. The heavy duty design and high power of these high bay lights also makes them suitable for a wide array of applications including but not limited to: military, 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 LED 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.
