If you overdrive an LED for more light output and/or it overheats, it will get dim.
This gets more important if your light fixture is too small and sealed. I've been lucky with my bedroom light, it is one of the 15" inverse glass dome type, which seem to be popular and I like them. My 2 8 watt LED lamps aren't getting too hot in the enclosure and after using them for almost two years(if I recall on the time correctly), they seem as bright as when I bought them. These are Sylvania Ultra 3000K LEDs (LED8A19/G2), the box says 50,000 hours life and 430 lumens. These make my room brighter than the two 13 watt CFLs that they replaced, even though the lumen level is lower than what the CFLs were rated for. ..and I don't have to wait for them to warm up to give me full brightness.

For what it's worth. "Assembled in US from domestic and foreign components" is on the box. They used to be $40 when I got my first one, then I immediately bought a second. Now I have a total of 5 after they went on sale during $10 and $15 sales at Menards. The packaging says they are compatible with dimmers but for the best efficiency of the lighting in my house, I put the appropriate light output in each fixture so that I have it as bright as I want.
