Some will naturally wonder why they don’t just make LEDs that mimic the incandescent spectrum instead. After all, there are LEDs in all sorts of colors out there. Surely those smart engineers could figure it out. I am sure that they could. In fact, someone has probably already done it. Unfortunately the particular elements used in the production of blue light LEDs (from which “white light” LEDs evolved) happen to be the most economical and efficient ones around. Switching the spectrum to be more in line with that of the incandescent bulb would impact both the cost and the efficiency, which might put a damper on sales. If they could somehow figure out a way around that then there might be a hope for better quality LEDs. Until such time I will continue to stick with the incandescent as my choice for the light bulb with the highest quality of light.

The first is that one of the big problems with CFL is "flicker." Apparently it is also a concern with LEDs. While it may cause problems for people with epilepsy, it can also contribute to malaise, headaches, and impaired visual performance. Alan shared this link as a starting point.
Perhaps this one is solvable with the right design, but until then I think it's a fair concern.
