Pro Series D2C LED Bulb

The Heise Pro Series LED bulbs are an upgrade designed to replace D2S and D2R HID bulbs, offering superior performance over traditional lighting. These bulbs boast a 260% increase in brightness compared to other LEDs, providing 16,000 lumens to enhance nighttime visibility. They operate efficiently, using only 70 watts per set and maintaining a running temperature of 115 degrees F, which contributes to a longer lifespan. Engineered with an extreme LED chipset and a 2mm solid copper thermodynamic core, these bulbs feature all-metal construction for durability. The design meticulously optimizes LED placement to maximize the optics of both projector and reflector housings, facilitated by a unique collar that allows proper keying into "S" (projector) and "R" (reflector) housings. Features include instantaneous full lumen start-up, an IC thermal controller with a high-speed smart fan, built-in reverse polarity protection, and a side-cable connection for easier installation. An integrated EMI filter ensures no interference with the vehicle's radio reception. The bulbs accept a 12-24V DC input and connect to the factory ballast. Important considerations include that these bulbs are for off-road use only and are not street legal. It is recommended to keep the original factory bulbs for use on public roads and to store the new bulbs carefully when removing and reinstalling them. Heise offers a 3-year warranty on these Pro Series LED bulbs.
