Built with the same top-tier components as the $250+ headlight bulbs, in a smaller body, for about 40% less. And every number on this page is a real number.
Almost every LED headlight listing makes the same promises: huge lumen numbers, “super bright,” “best on the market.” Here is what really separates a great bulb from a bad one, and how the LX1 handles each.
Every LED headlight is brightest the second you turn it on. As the chip heats up, its output drops, and on many bulbs it drops a lot in the first few minutes. Then it levels off and stays there.
That leveled-off number is the brightness you actually drive with. But the turn-on number is the one that ends up on the box, because it’s bigger.
We publish both. The LX1 fights heat with a built-in cooling fan and a 6063 aviation-aluminum body, so it holds on to more of its brightness once it’s warm.
All numbers are per bulb, at 14.5V (normal running voltage). When you compare bulbs, ask two questions: is that number per bulb or per pair, and is it at turn-on or after warm-up?
Your headlight housing was designed around a halogen filament sitting in one exact spot. If an LED’s chips sit even a few millimeters off, the housing can’t aim the light. You get glare in oncoming drivers’ eyes, dark patches on the road and a fuzzy cutoff. Some bulbs even put the low beam on the same line as the high beam, so you have to re-aim your headlights to make them usable.
A good bulb drops in and works, with no re-aiming, in both reflector and projector headlights.
Most people never think about this one, and it’s the one that can cost you the most.
An LED headlight pushes its heat backward into the metal heatsink at the base of the bulb, and that heatsink gets hot, too hot to touch after a long drive.
On many LED bulbs, especially smaller and cheaper ones, your car’s factory plug clips straight onto that hot heatsink. Your plastic connector and the wires behind it end up soaking up the bulb’s heat, night after night.
What that leads to: a melted or brittle factory connector, flickering, a headlight that cuts out, and in the worst case a damaged wiring harness. That repair costs far more than the bulbs did, and it’s why so many people online say “my LEDs melted my plug.”
Isolated wire lead. A molded lead sits between the bulb and your factory connector, so your plug never touches the heatsink.
Fan pulls heat out the back. A built-in fan draws heat away from the chips and out the rear of the bulb.
Aviation-aluminum body. The 6063 aluminum heatsink sheds heat fast, so the chips run cooler and stay brighter.
On a lot of LED bulbs, the driver (the electronics that power the chips) hangs off the back in a separate box you have to find room for. On the LX1, the driver is built into the bulb itself.
That makes the LX1 much smaller overall than our previous LumX headlight and fog bulbs. It’s brighter and better in every way, and it fits tight, hard-to-fit housings that bigger bulbs can’t.
The LX1 is built with the same top-tier LED chips, drivers and cooling hardware used in the $250+ bulbs from the biggest names in the industry. Same class of parts, built to the same standard.
It costs about 40% less because you’re not paying for a big brand name, or for the marketing machine behind it.
Scroll through LED headlights online and you’ll see 20,000, 30,000, even 40,000 lumens. Those numbers aren’t real. They’re usually both bulbs added together, measured for a split second at turn-on, or simply made up, because nobody checks.
The LX1’s numbers are real, per bulb, at normal running voltage. And we show you the number after warm-up too, because that’s the one that matters on the road.
Quick reality check: a good LED headlight makes about 100–125 lumens per watt. Multiply a bulb’s watts by 125. If the lumen claim is far above that, it isn’t real. A 40–50 watt bulb can’t make 20,000+ lumens.
LX1: 43 watts per bulb, 5,300 lumens. The math adds up.
Every LX1 set is covered for 3 years. If a bulb fails, we take care of it.
