PWM Control: The pulse width modulation drivers in this unit also provide secondary benefits through the ability to tap into a provided input wire with an external pulse generator and adjust the duty cycle of the current being applied to the LEDs. The end result is more light with less heat and longer LED life with an average 70% lumen maintenance after 50,000 hours. 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. This allows the LEDs to be driven at up to 100% capacity without overheating or visible loss of light output. 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 system in essence flashes current at an extremely fast on and off rate to each LED based upon the LEDs core temperature. 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. These LED light bars 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. Click to Enlarge Photo Heat Management: Heat is the single largest factor in premature LED failure and color shifting. An integral Pulse Width Modulation controller, small profile, low power requirements, high durability and versatile mounting system makes these LED light emitters a superior lighting solution for a wide array of applications including but not limited to: military, industrial manufacturing, machine visioning, security and law enforcement, boating, vehicles and commercial structure illumination. 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 environments, conditions and applications. We also offer floodlight versions with a 40 degree beam spread to provide more light over a larger area nearer the fixture, making flood versions ideal for use as work lights. Eighteen CREE XLamp MC-E¨ 10 watt LEDs producing 860 lumens each are paired with high purity optics to produce a 20 degree spread spot beam approximately 1200 long by 140 in width. The LEDP10W-180ET trunnion mount LED light bar from Larson Electronics produces 15,480 lumens of bright light while drawing only 180 watts amps from a 12 volt electrical system. 15,480 lumen light output with low voltage and amp draw, a 50,000 hour rated service life and 9 to 46 volt compatibility provides operators with a versatile and powerful LED lighting solution.
