DURABILITY
As well as unparalleled heat control, the LEDP10W series of LED light bars 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 85 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 MC-E® LEDs offer resistance to shocks and vibrations and are rated at 70% lumen maintenance after
50,000 hours of use.
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 100% 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 tap into a provided input
wire with an external pulse generator and adjust the duty cycle of the current being applied to the LEDs. Thus you can
connect an external dimmer, switch, or pulse control and adjust the perceived output of the light, effectively causing the light
to flash, dim or brighten to the desired levels.
Additionally, this method of controlling light output results in a corresponding drop in amperage draw, so if the duty cycle is
cut back to 50% there will be a matching 50% reduction in amperage draw. These units are also able to monitor and adjust
input current to maintain the correct LED voltage levels regardless of input levels across a specific range. These LEDP10W
series light bars can operate on current ranging from 9 to 46VDC 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.
