OPTIMAL HEAT DISSIPATION
The next thing you’ll notice is their all-new patented aluminum alloy leaf passive heat sink. Its compact and readily configurable design allows an easy fit in most any headlamp housing, and with its much larger contiguous thermal path, it does a better job shedding heat off the LEDs than past-type flexible mesh heat sinks. With no flex-mesh junctions to break and no motorized fans to make noise and electrical interference, clog, or fail, the superior heat rejection performance of the alloy leaf passive heat sink is retained over the long haul, for the full rated life of the emitters. That translates directly to excellent performance; the cooler LEDs can be kept, the higher their output.

BEAM PATTERN
The emitters themselves are genuine Lumileds ZES, three on each side of the light head, and this together with their undomed configuration means they closely replicate the size of the H11B halogen filament. That means a better optical match than longer 4-emitter arrays or domed COB emitters, both of which violate the light source box your headlamp’s optics were designed around, and because the high output comes from three chips rather than four, luminance is higher for better beam punch and spread.

LUMENS & LIGHT OUTPUT
Speaking of output: anyone can throw around inflated lumen numbers — and most vendors do. Some of those numbers have no basis in reality, they’re just fibs. Some of them are somewhat accurate, but only immediately after the bulb is lit up in a cold chamber, without accounting for the significant droop that happens when improperly chosen emitters are inadequately cooled – don’t drink the kool-aid! Our new H11B Xtreme Pro bulbs are rated honestly: 1900 lumens stable, measured after the bulbs have been operating continuously for an hour in 60°C / 140°F heat. That’s a rating that means (and gives you) exactly what it says. And with the 5500K color temperature of our emitters, we’re giving you true white light, not artificially jacking up the lumen rating with a bunch of useless deep-blue light that can only attract unwanted police attention, not help you see.

THEY’RE JUST BETTER
There’s more clean-sheet engineering where you can’t see it: we’ve used copper circuit boards for optimal thermal conductivity, and our compact base means the rigid tail of the light head is only 25mm — much smaller than other LED bulbs on the market. You’ll note the light head is remarkably compact, without bulky over-length that prevents many other LED bulbs from fitting all the way into many headlamps. And the light head is clockable, too, so you can fine-tune the output for the best optical match with any lamp you might install them in.

Truly, this is the top-performing LED bulb with OE-level quality and “fit it and forget it” durability and dependability.
