What color light is the most relaxing?
“Blue lighting accelerates the relaxation process after stress in comparison with conventional white lighting,” the researchers confidently declared.
What light bulb is closest to natural sunlight?
Halogen bulbs are a type of incandescent that gives a close approximation of natural daylight, known as “white light.” Colors appear sharper under halogen light and the bulbs can be dimmed. They’re a little more energy efficient than incandescent bulbs, but they’re more expensive and burn at a higher temperature.
Are daylight bulbs bad for your eyes?

Which light bulbs are safest for eyes?
Compact Fluorescent Lights (CFLs): CFL bulbs produce fewer UV rays and are more energy efficient than bright white incandescent and fluorescent tube bulbs.
Which light is bad for eyes?
