> One problem I can see (no pun intended) is that many LED lights actually use a bulb coated with phosphors, and the LED in the bulb is used to excite the phosphors which then glow giving off the light that we see. I'm not sure how quickly the phosphor stops glowing when the driving LED turns off.
Unfortunately this is how all white LEDs work, and the retention time is tens of miliseconds. It's an interesting idea though, based on the old shutter 3D goggles. Since it would rely on the eye adapting to the flickering darkness, it would be very dependent on how good the light seal round the edges of the goggles is.
