HELLA H1 YL Xtreme Yellow Bulbs, 12V, 55W

I bought these bulbs to use as high beams on an aftermarket HID projector kit I bought for my truck (the high beams on that particular model are halogen and are not projector). These are exactly what I expected and well worth the $14 I spent on them. They are about as bright as a standard 65W high beam bulb. I say this because they are 100W (brighter) but they use a blue tint (which reduced light output) to reduce the yellow in the light and make them appear whiter. The result is a bulb which is about the same brighness, whiter, and a much shorter lifespan. I highly recommend carrying spares of these bulbs if you don't want a ticket for driving with a headlight out. Also, while they are much whiter than regular halogen bulbs, they are not as white as my 6000k HIDs (which I also expected). All in all, I got exactly what I expected plus spares for what I consider a very resonable price. For that reason I give these five stars.

These work fine, although I'd prefer dichroic PVD metal oxide coating to the yellow colored capsules.

Works as they should. Lets see how long they last.

Well packaged Easy installation good price great color reluctantly I took a star away just wanted them to be brighter only 55 watt really wanted 75 or 100 but couldn’t find any I tried led’s and they were even worse but I do like the color and quality of Hella products

Not long lasting

I bought a single lamp by the same manufacture earlier. It didn't last. Maybe it was defective. So I Bought this 2 pack for my scooter headlight bulb replacements. One for Hi and one for Lo. The first time powering them up both of them burnt out in less than 30 seconds of use. Yes they're cheap but I assumed they would last longer than to the end of my driveway. Maybe I'll try LED's. These absolutely aggravated me since it takes quite awhile to replace them both. I have a TaoTao 2020 Thunder Blade. Lamps are H1-35 watt and these replacements are H1-55 watt. Total Disappointment!

The Hella Optilux XB Series H1 Xenon White Halogen Bulbs deliver impressive brightness and a crisp white light that significantly improves nighttime visibility. Installation was quick and easy, and the difference in clarity compared to standard halogens was immediately noticeable. These bulbs look great and perform very well on the road.However, the biggest drawback is their longevity. For a reputable brand like Hella, I expected these to last longer. Unfortunately, they tend to burn out quicker than I’d like—especially at this wattage—and that’s disappointing for what is otherwise an excellent product.If you’re looking for strong light output and don't mind replacing bulbs a bit more often, these are a solid choice. But if durability is your top concern, you may want to explore other options.

I'm an idiot and was bench testing headlights I was making, gave em 18v. They got quite bright for oh 2 seconds and then suddenly no worky. Naturally I assumed one was faulty and did it to the other one, shocker the same result.So uh, don't do that. For the brief time they were alive, they were quite bright
