It's amusing for me to read that as I feel the exact opposite where it comes to illumination. I dearly miss the feel of warm, orange yellow lighting from incandescents indoors and sodium lighting outdoors.

My main beef with LEDs is being in proximity of cheap LEDs with low refresh rates - there's a shop I've stopped visiting because I get a sore head within minutes of being in there, from seeing everything clumsily strobe. Ironically, they sell lighting. I've talked to the boss in there, but he just doesn't see it.

I do wonder whether younger kids sense visual refresh rates moreso than older people, and if so, what effect that might have on them. Certainly stresses my bonce.

It is perfectly possible to have warm and very nice-looking lighting with LEDs.

You'll have to buy more expensive LEDs and drive them with well-designed electronics.

Yuji LEDs are some of the best.
