Hi Marco,
Best LED lights please? 5200K and a refresh rate that doesn't make me want to vomit?

I've been extremely impressed with Waveform Lighting's A21 bulbs and linear tube fixtures.
I don't notice the refresh rate on most good LEDs (only on half-wave-rectified garbage, like cheap holiday lights), so I can't really report anything there.
Where Waveform really stands out is ridiculously high-quality light color, with very impressive CRI performance and a very natural look. I go 4000K for my office.
