One thing they are missing is collimation. You might want the light rays to be parallel, to simulate the far away sun and to get sharp shadows. I tried to come up with a solution to do this in a flat package, but optics is not my strong suit. Generally, you always have a trade-off here: If you want to get rid of the harsh point-like light sources, you have to add a diffuser, and then you get indirect light. But too d…

Watt-hours are energy. If cost of energy is decreasing and you get more lumens per watt with LEDs then the benefits stack, they do not cancel.
If energy price is going down, then even more watts are being bought (since spending is fixed).
Adds up considering the proliferation of computing devices, particularly cryptomining.

Would you tell us a little about your photophobia, I've never heard of anyone having that before. Thank you.
I have a neurological disorder called visual snow syndrome that's the root cause, nobody really understands where it comes from but the current theory is a dysfunction of metabolism in part of the visual cortex. It causes all sorts of weird visual stuff like the eponymous 'tv snow' and other distortions as well as intractable headaches, apparently it has similarities with certain kinds of migraine. As for the photoph…

FWIW, I just replaced a lot of bulbs in my house with Philips Hue white ambience bulbs because I'm very sensitive to flickering and we dim a lot. So far, no buzz or flicker. They are expensive, and so is everything in their ecosystem, but I finally have a light I like dimming.
My experience with the Philips Hue was: not bright enough. That was admittedly years ago when they were the new hotness. Perhaps they are brighter now. Also, I don't want "an app for that" with my lighting.
