LED light bulbs are pretty efficient at this point, so what I would really like to see is LED light bulbs that produce higher quality light.

Due to how they work, most LED lights have color rendering index[1] of 80 or below. We have the technology, and there are some that have CRI above 95 within a reasonable price, but they are not so easy to find. It would be nice if there were more LED lights with CRI above 95 especially in the 4000K to 5500K range. I have one at home and the light is just beautiful.

I looked for an LED with a high CRI and 4000K color, but I couldn't find any. What is the brand of the one you have?

There is one Philips ExpertColor model that is 4000K and has very high CRI.
