Is heat a "cumulative" thing, or does it get "reset" each time you use your LED light?
Let me see if I can explain my question more clearly. I am not talking about driving a light at higher than recommended voltage. I can easily see where higher voltage might easily degrade a circuit and/or LED emitter in such a way that it eventually fails. (Even though it might work for quite a while, before it eventually fails.)
What I am talking about is a light that is driven at recommended voltage, but tends to slowly get hotter and hotter. (Or perhaps, I should say "warm" since I am not talking about something that is truly scorching to the touch.)
Does such heat eventually damage (lower the life expectancy of the light) by cumulatively harming parts? (If so, does that mean you might want to try to keep your lights as cool as possible?)
Or, so long as you "get away with it" at the time (meaning, so long as the light doesn't actually die when it gets "very warm"), would you say the life expectancy of the light is "reset" back to normal again the next time you turn it on?
I hope my question is clear. Sorry if it is a dumb question.
