The power supply is the weak point in LED room lighting. The best power supply for LEDs is switch-mode PWM, high frequency, and with thermal management designed by an engineer who understands therodynamics.
Unfortunately all those things are expensive so you rarely find such bulbs in the cheap bin at Home Depot.
Bulbs are actually a very bad form factor for LEDs, because they concentrate two heat-generating components - the PSU and LEDs - into a small chassis. LED tape with a separate power supply is probably the best solution that's not a full-custom DC light fixture.
