kind of hard to have 50,000 hours of use. That would be 5.7 years of being on constantly. I put LEDs in my house when I bought it 7 years ago and exactly 3 have failed. Mostly, it isnt the LED that fails, it is the power converter/supply.
Just out of curiosity, How many people have had their LEDs go out in their Maverick? we may just need some data.
My Cruze DLR are just the headlights. I can't tell if the power is lower, or just the same. I have never checked. I did swap out the halogen bulbs for LED a while back and love the results. There are little fans on mine to help keep them cool.
Just to play devils advocate, there have been studies that show tail lights on during the day is hazardous. I cant find the study I read, but that is why they offer DRL that don't turn on tail lights. I think it had something to with the brightness shift of read is harder to see in the day and people are less likely to tell that brakes are applied. I have had trouble telling the difference of some tail lights vs brake lights in the day, especially if the center light is burnt out.
Still a failure.
Understood, but for me I am not going to stop doing something because it might happen. I might get in an accident every time i get in my car. I am still going to drive. I bought a TV to watch, but if I use it, it might wear out, so I am just not going to use it. My DLRs might go out early, but I am still going to run them. If they fail, or even when they fail, I will determine then if I think it is worth replacing.
On both sides.
The cree led had a silicone carbide substrate and also used it in the chip structure itself. When cree sold the led business they sold the cree name and retained other separately owned corps and patents. The silicon carbide business is now called Wolfspeed and is building a chip manufacturing plant in SC something like $2.?+billion. They sold first right of refusal to auto parts manufacturing Co for (20%?) of capacity. Silicon carbide aka carborundum has a phase change temp in excess of 1700°C so it's at home in high temps. I understand one way to dim LEDs is to control current and use two banks of LEDs on alternating current. If each bank has say 10 leds and current is kept the same when one of more LEDs fail the remaining LEDs burn brighter which of course shortens their remaining life but the bulb will maintain it's lumens until the last 60% of LEDs start dropping like flies. The other bank is wired with reverse polarity and as a result is brightest when the other bank is dark. Yes they alternately flicker on and off at 60 cycles/second in US but anything faster than 25-30 times a second cannot be determined by human eyes.And the other post is wrong.
Modern high output LED get hot. VERY HOT.
I think the point I was trying to make was that My bulbs that are still working (Probably close 60) have not had the opportunity to get anywhere close to their 50,000 hour rating. SO far, I am at about 5% failure. All of my bulbs that did fail were all "older models" and were early generations. I have not had a new LED Bulb go out in over 5 years.
Have you noticed color temperature shift over the years? The older they get, I think they get yellower / warmer.
