Question: what is the difference between cool white and warm white fluorescent bulbs?
Answer: Soft white (2,700 to 3,000 Kelvin) is warm and yellow, the typical color range you get from incandescent bulbs. This light gives a warm and cozy feeling and is often best for living rooms, dens and bedrooms. Warm white (3,000 to 4,000 Kelvin) is more yellowish-white.
