rimthin 9006/HB4 Bulbs, HB4 Fog Lights 6000K Cool White IP67 Waterproof, Pack of 2

( I have added and update to the bottom)This is more of a first impression than a review, since I only got these yesterday. I have 2016 Mercedes E350 with the standard LED light package. Meaning, I have H7 halogens for high beams. When you hit the high beams, the contrast between the 6000k LEDs and the 3550k (Osram Night Breaker 200 in this case) is annoying. As good as the Night Breakers are, they are no match in color or brightness of the LEDs. I was looking at the Osram Night Breaker LED Speed H7 as a direct 1:1 replacement, but acquisition was complicated and I am impatient. Enter the RimThin H7 LED. I was worried these would cause warning messages on my Mercedes canbus system. No problem there. I was concerned that the color would not match the factory 6000k. Also a non issue. It looks like the factory kelvin is closer to 6300k and these are a true 6000k, but that is only if you observe very closely. I was also aware that some of these aftermarket LEDs have a slight delay when switching them on. Again, no problem at all. These come on instantly, maybe even slightly quicker than the factory lights? My final concern is about reliability and longevity. While these are very cheap and easy to replace, I don't want to replace them after 6 months. If they last two years, I will be satisfied. Any less than that will be annoying and I will find myself wishing I had stuck with the Osram LED Speed Option at 6x the price. As a side note: My friend has the exact same car with the upgraded ILS light package and we parked them side by side last night. My factory low beams are brighter/ better than his AND my new RimThin H7 LEDs are FAR brighter, better than his $$$$ "upgraded" ILS high beams! When I shopped for this car, I was disappointed that I could not find one with these 'upgraded' lights, now I am happy I didn't get the ILS system. My Lights look and function amazing now. I will try to come back and update this review if I have any rants or raves about these, lights, but so far, so good, Update: I bought these to use with my Mercedes as mentioned above. The brightness and even lighting of these was very good but- I was occasionally getting a Canbus alert to check the passenger side bulb. I have since learned that any bulb that does not consistently draw 30+ watts will trigger this. So these do not work for me. I have since ordered the "AUXITO H7 LED Bulb 30W 10000LM 6500K Cool White with Cooling Fan". These are about exactly double the price, but they work perfectly- no Canbus alerts!. As for the Rimthin H7 bulbs, it just so happens I have a 100 series Landruiser in my yard with aftermarket 'Depo' light housings that take H7 bulbs for high and low beams. I have installed these for high/low and they are amazing and because the Landcruiser has no Canbus type system, no alerts will ever happen!. I will try to update here again if I have any issues with these in the Landcruiser.

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.

I bought these LED bulbs for my car, and I’m extremely satisfied with the upgrade. Installation was quick and easy—they fit perfectly into my existing socket with no modifications needed. As soon as I turned them on, I noticed a major difference. The brightness is impressive, far better than my old halogen bulbs. They produce a crisp, white light that improves both visibility and the overall look of my vehicle. Driving at night feels much safer now. The beam pattern is clean and well-focused, without blinding oncoming drivers. These bulbs light up the road evenly and help me spot obstacles, signs, and lane markings much more clearly. They also have a modern, stylish appearance that gives my car a refreshed, premium look. So far, there’s been no flickering or error messages on my dashboard, and they’ve stayed cool to the touch, which tells me they’re energy efficient and well-designed.

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).

Super éclairage, très blanc par contre

Sorprendido de la luz, se ve muy blanca e ilumina bastante. Y es muy fácil de instalar no hay que modificar nada. Renault captur.
