What light color should I choose?
Warm White is equivalent to a standard incandescent light color and is most popular for residential applications. It has a slight warm yellow glow to it that many people find comfortable and we are all used to seeing in our homes. It is a 2700-3000K on the Kelvin Light Color Scale.

DayWhite™ most closely replicates natural daylight and does have a slight blue hue to the light output. This is rarely seen in residential applications as the light output can seem a bit harsh and bright, and is most commonly seen in exterior or commercial applications. This is the brightest of the White light color options. It is a 5500-6000K on the Kelvin Light Color Scale.
