FUNCTION

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.

 

BULB DESIGN

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.

 

COLOR

These LEDs illuminate in a crisp, cool, bright, white hue for maximum light output.

 

BRIGHTNESS

210 Lumens

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. Please click here to learn more about LED brightness measurement.

 

QUALITY

LED Components. Diode Dynamics uses only the highest quality LED chips in the production of its bulbs. This means we use only brand-name suppliers such as Epistar, Cree, Osram, and Samsung.

While our bulbs may look the same as others on the market, most copycat bulbs use economy-grade LED chips in order to reduce costs. This greatly reduces the reliability and overall brightness of the bulb when you compare it to Diode Dynamics.

Construction. Although LED technology allows for extremely long bulb life, the market is flooded with cheap LED bulbs that fail prematurely due to inferior construction. The worst enemy of LEDs is excessive heat, and when bulbs are not designed properly, they do not disperse heat as well, leading to premature failure.

Off-brand, cheap bulbs exhibit poor solder uniformity, high levels of flux in the solder, uneven chip placement, low-gauge terminal wires, poor assembly, and bulbs held together with inferior adhesives. At best, solder joints will crack and fail on low-quality LEDs after a few weeks of use. In the worst case, these bulbs can damage housings as the extra flux and adhesive evaporates and creates a residue on the lens of the housing.

Diode Dynamics bulbs are produced with modern, computerized equipment, and only the best materials, to ensure complete uniformity, high quality, and long bulb life.

All Diode Dynamics products come with a 30-day satisfaction guarantee and a 3-year limited replacement warranty. For more information, please view the FAQ guide.

  2. Backup bulb for 2013 Focus ST Review by Sid

    Quality

    I was looking for a nice white LED bulb to replace the stock halogen bulb. The HP36 fit the bill perfectly. They were plug and play installation and the bulbs had a very white color temp with no blue or purple tint to it like many cheap eBay LEDs have. They are slightly brighter than my stock bulbs without being too overpowering at night for the people behind me. I just wish the bulb was a bit cheaper though they quality is very good.

    I own a 2013 civic si with tinted windows and I would need to roll my windows down at night to see so I can back into my driveway. Now that I installed these super bright LED's, I no longer have to roll my windows down to back up at night. I would highly recommend these to anyone in the market for LED reverse lights.
