How are “Daylight Lamps” different from standard white LEDs with the same power? What gives them the therapeutic properties?
In: 17
Daylight light bulbs attempt to simulate daylight by outputting all wavelengths of visible light. Which is more than what is necessary for a bulb to appear “white”.
Since our eyes only have three types of cone receptors for color information, all it takes is for a bulb to output some combination of red, green, and blue, and it will appear white. This is what most bulbs do. A daylight bulb tries to emit all wavelengths though, which includes wavelengths between red and green, and between green and blue.
Which means that not only do daylight bulbs have “therapeutic properties”, they also result in more accurate colors of objects being illuminated by the light. Ever wonder why some objects look a different color in daylight and indoor light? It’s because of the missing wavelengths from regular indoor light bulbs. A daylight bulb makes the color more accurate.
