LEDs seem, at least, to be wonderful. If some people are bothered by the 60Hz oscillation, I would think that it would be possible to power LEDs with DC, which wouldnt have the problem.It definitely would be an added cost, I admit - but its beginning to look like LEDs are cost-effective, so it might be tolerable. Incandescents do burn out . . .
At least itd beat going back to kerosene lamps.
Its not about money its about medical condition. See my posts above.
