[CQ-Contest] Dimly lit working environments:

[AC0W]

Some of the lamps will have a color tone or color temperature (not all 
vendors do this for residential lamps). You want color temperatures 4100 
K and higher, such as 4100 K, 5000 K, and 6500 K. You do not want color 
temperature below 4100 K or avoid 2500 K, 3000 K and 3500 K.

This applies to both LED and fluorescent lamps.
