I bought these just under a year ago, and had one of the bulbs flicker at about the eight month mark, and eventually die altogether after about 11. I tested it on my electronics workbench and it was giving off maybe 40 lumens with the cooling fan free to move but not activating at all at standard V/A that a car would feed it while running normally. I contacted customer support, but am not sure they'll even offer a replacement bulb, since they only offer a 90 day warranty, and one of their two support options hangs up during business hours. UPDATE TO BOTH UPDATES ETC: The full replacement set showed up on Thursday evening, and I've got the H11 installed, and have two backup 9005s and a backup H11 in case anything happens anytime soon. I have to say, it was somewhat of an inconvenience to have a non-zero failure rate on the bulbs, but the customer service Rimthin provided was better than I could have predicted from a company I'd never researched and randomly bought from on Amazon. UPDATE: I received a call back from Rimthin customer support, and was informed they do have a 1 year warranty, which is separate from the 90 day return policy. I was told today to wait for one to two business days and I'll receive an email detailing updates on the shipping of the replacement I'll be receiving. For now I'll leave the review updated to 3 stars, and will update if I receive the email/replacement. UPDATE PART TWO: I got an email from customer service like I was told I would, sooner than I was supposed to expect. they wanted my order number and shipping address, so I responded with that. got a response in about 15 minutes and asking if I needed the h11 or the 9005. I let them know I needed the h11. since they were out of just the h11s and packages, they sent me another four pack. The tracker says it's going to show up tonight by 11:00. Read more

I've done several LED conversions on automobiles and motorcycles before. LEDs tend to be brighter, last longer, draw less power, and create less heat than incandescent bulbs. One family member has a car that just eats headlight bulbs. Incandescents last about 6 months. Two different sets of LED bulbs have given up between the 12 and 18 month mark. My guess is that the headlight housings trap a lot of heat, and this eventually cooks the bulbs to death. This is the 3rd set of LED bulbs that I've installed in that car. The last set shorted out completely, taking a pair of 15 amp fuses with them in the process. I temporarily installed incandescent bulbs that I had laying around until I could order these, which I chose based on reviews and price. The incandescents provided barely adequate light output. They're just not very bright and they make it difficult to see at night or when it is rainy. When these bulbs came in, I installed them and was immediately impressed with the light output. They're not obnoxious (in my opinion), but they sure do make it easier to navigate a dark, winding road. Both of them worked out of the box and they provide a nice, bright headlight beam with a good pattern. How long they will last is anyone's guess, but based on previous experience I'll be buying replacements in about a year and a half. That's still 3X the life of an incandescent bulb in this application, and while I wish they'd last even longer (the LED headlights in my car are 3 years old and still going strong), I guess I'll live with it. I'm knocking a star off because I'm skeptical about the long-term durability of these bulbs. After some miles and time in the car, I'll update my review. For now, I can tell you that they're bright and they fit perfectly. For the $20 that these cost me (less than premium incandescents), that's a win. Read more

Excellent for the price, bright enough to be confidently driving in any weather with tinted windshield. The exact candela output (lumens are meaningless) will depend on design of your headlights. I took a few measurements for the lighting nerds out there though... CCT: 7637K, quite a bit colder than advertised. CRI: 76.6, pretty respectable for cheap emitters. Naturally, the biggest dip is in R9, which reads at -1.8 (yes, that's a negative value). In other words, it absolutely sucks at reproducing deep reds. R12 is barely adequate and reads just below 40, so don't expect faithful blues either. Oh, and then of course there's duv. In this case, duv = -0.0016, which is within both ANSI and EnergyStar recommended ranges. To summarize, the light is adequately bright, flicker-free, cold and very neutral with a slight magenta tint and pretty bad (although expected in this price range) red reproduction. More than adequate for driving, but if you're looking for headlights to use in professional photo or video production - get a Beamtech (which costs 10x more, sadly). Read more
