Diode Dynamics 921 HP36 LED (single)
921 HP36 is a direct replacement for any 921 size halogen bulb. These are recommended for 3rd brake or underhood lights.
By changing the factory bulb to an LED, you can illuminate the area with a much brighter light, and add a pure white, luxury look.
The installation is 100% plug-and-play, just replace your factory bulb.
HP36: Full 360 degree illumination with 36 High-Power Samsung LEDs. Aluminum base for optimum heatsinking, and non-polar design for easy installation.
The LED is wired for 12V operation, the kind found on all vehicles.
Included in your order is ONE BULB.
These LEDs illuminate in a crisp, cool, bright, white hue for maximum light output.
Lumens: BUYER BEWARE! Most sellers just provide "calculated" lumen numbers, based on the maximum potential brightness of the LED chips on the bulb. For example, if a bulb has five 10-lumen chips, they will rate it at 50 lumens. However, this is not accurate, as the design of an LED bulb does not get rid of heat fast enough to run the LEDs at maximum.
These "calculated" lumen ratings are much, much higher than the true, measured light output, so it will look like competitors' bulbs are brighter than ours. This is because Diode Dynamics does not provide inflated "calculated" numbers; we believe it is misleading. We test the actual brightness of the bulbs in our lab, to provide real lumen output measurements. Our measurements are accurate, but they are usually much lower than the misleading "calculated" figures.
