Most people recommend the "warm White" 3,000 - 3,500 K
I have been trying to find some 48 SMD panels in the 4,000 K range
I find the Warm White 3,000 - 3,500 to be to soft/yellow for me.
Here is a Chart:

Color
Temperature Common Example
2000° Gaslight
2470° 15 watt incandescent bulb
2565° 60 watt incandescent bulb
2665° 100 watt incandescent bulb
2755° 500 watt incandescent bulb
2900° 500 watt Krypton bulb
3100° Projector type filament bulb
3250° Photo Flood
3400° Halogen
3900° Carbon arc
4200° Moonlight
4700° Industrial smog
5100° Hazy weather
5500° Sun 30° above horizon
6100° Sun 50° above horizon
6700° Electronic Flash
7400° Overcast sky
8300° Foggy weather
30,000° Blue sky
I'm going to order 6 pcs 3k & 6 pcs 5k to start and see which I prefer and move the ones I don't like to areas that are not important.
I'm looking at the 48 SMD Panels most rate the Lumuns @ 190 a few I have seen are 210 Lums.
