The LED itself is rarely if every the problem, it is the cheap Chinese
electronic power supply paired with them.
The key is to try to figure out which brand uses decent electronics.
Another variable to consider is the quality of the local power grid.
If you are seeing a lot of surges and dips the electronics are more
likely to fail early than if your source is steady.
EPA regs have become more absurd over the years so that when applied
to CFLs the absurdity becomes more apparent.
