Diode Dynamics 921 HP5 LED (single)
921 HP5 Bulb is a direct replacement for any 921 size halogen bulb. From the factory, the bulbs are incandescent, lighting up in a yellowish color.
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.
HP5: Four high-power SMDs, under a diffusing lens. Just like the HP3, but run at higher power, with integrated copper plating for superior heat dissipation, allowing maximum brightness.
Included in your order is ONE BULB.
These LEDs are available in crisp, bright colors including Cool White, Warm White, Blue, Red, and Amber.
We strongly recommend Cool White or Warm White for the best visibility.
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.
