Not all types of LED are so fragile. GaN LED show negligible decay even with heat-sink temperature at 105 degrees Celsius when compared to one whos heat-sink maintained 55 degrees Celsius. Yes, I know that this is just a recent research paper and not something available right now, but your point regarding temperature dependence might be much less significant in the near future when compared to current state.If you drive them hard in a hot environment its significantly worse.
