Does anyone have any data on how fast an LED bulb or flood lamp could be driven with a triac or something, at x number of Hertz slower than the "flicker fusion threshold", and have the results still be interpreted as discrete flashes? I'm assuming LED bulbs/flood lamps run off 120 VAC still do not have anywhere near the same thermal inertia that incandescents do.
Would driving them at a rate slow enough that they're not responding to the RMS value of the waveform cause any damage to the lamps?
