H11 Xtreme LED Pro Headlight Kit | H11 LED Low Beam and Fog Light Upgrade
The H11 Xtreme LED Professional series of plug-and-play headlight bulbs are made from premium materials. Hold one in your hand and you will notice their high-quality fit, finish, and feel.
Heat Is The Enemy
LED lights come on instantly and emit the most light while the bulb is cool. As the bulb gets hotter, the emitters become less efficient and may have as much as a 50% "droop" in lumens. Worse, if an LED bulb is run too hot for any length of time, the emitters degrade and the bulb eventually burns out. Xtreme Pro H11 LED bulbs feature a passive aluminum leaf heatsink that’s designed to be bent, folded, and molded inside the headlight housing. The solid aluminum fins do a significantly better job of shedding heat than our previous flexible mesh heat sinks. No need for noisy fans or other moving parts – our leaf heat sink works, and works well.
Beam Pattern Matters
Automotive H11 halogen headlight systems are designed around a bulb's glowing filament to deliver the proper low beam and high beam patterns. Xtreme Professional Series LED Headlights are precision engineered with LumiLED emitters positioned to create optically correct beam patterns. To ensure emitter placement is optimized when the bulb is twist-locked into its socket, Xtreme LED Pro H11 Headlight bulbs have an easy to adjust precision alignment feature with calibration index machined into the bulb's base.
We try not to use big words to describe our products -- as Einstein said, "If you can't explain it simply, you don't understand it well enough"... But, sometimes there's a good big word, and we like this one. In fact, it's the heart of LED lighting systems. "Electroluminescence" is the property of a material that emits light when it's charged with electricity, which is why we’ve selected premium grade Philips LumiLEDs for our bulbs. Thermal design, Kelvin Temperature, Physical Size and Emitter CRI & Placement have all been carefully considered in each bulb we sell.
