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.

I use one of those screw in florescent lights. How can I tell if it
has any
blue light component?
