If your LED lights are flicking or failing, it's likely not the fault of the LED itself, but the result of an inefficient driver. LED drivers contain AC to DC converters, and DC to DC converters for voltage regulation, but inefficiencies in these conversions cause thermal runaway. This, in turn, wears down device drivers and, ultimately, the quality of the light you see emitted from a fixture. See our blog for a further explanation of this.
