Craftsmanship: Designing a high-quality LED is a task GTR Lighting took seriously. Unlike so many companies that skimped on every single detail they possibly could, this H11 GTR Ultra Series 2.0 features a multi-faceted design that covers every base with real attention to detail.

The Best: While so many others use Philips or CREE LED chips, GTR went with a high-quality NLW753 option to ensure better results. Those results show through to the finished product too thanks to digitally optimized LED positioning that emulates the original filament location precisely. Combining these features is the key to getting all the light from the source to the reflector surface and ultimately onto your target without wasted lumens and glare all over.

Unstoppable: Consider this, GTR backs the performance of this LED light for life. They can be that confident because of all the work they've done to ensure it won't fail. The internals are 100% potted and waterproof for the wettest of trails or the heaviest rains. That means that the fan will never stop cooling either so temps never rise above 80c, well below the threshold for danger. They knew what they were doing when they assembled this rugged LED.

Better Fitment: We've heard many who assume that because the Ultra Series 2.0 is smaller than competitors that it's weaker and less capable. They couldn't be more wrong. Thanks to that small stature, it requires less energy to keep cool and keep power to the LED up. That results in 4100 lumens of output and a considerably easier time installing them. There are zero downsides here.

Best Warranty: We can't overstate this. You won't need another headlight bulb after these ones. They're so solid and strong that GTR backs them for life.
