These bulbs are not economical at all because I have to constantly replace them. Saving on electricity does not justify these expensive bulbs burning out in less than a year. The only two that have lasted are in my range hood for light above my stove. Those experience extreme heat and yet they are fine. I have had to replace 2 light fixtures that have permanent LEDs and no replaceable parts too.

    Not necessarily. Proper LED drivers adjust voltage to feed them a certain specified current. The driver will decrease voltage and heat more if it’s a basic transistor circuit but smarter circuits will just chop the power more. Even if it does supply the higher voltage due to use of a basic resistor circuit, there should be some safety factor that keeps the emitters below max power, so having 8% higher voltage shouldn’t affect longevity much. There’s many variables. Obviously everything I listed is regarding ideal conditions

      Ah, yes the LED driver is usually constant current type. I’ve been thinking too simply and assumed it’s constant voltage.
