How are “Daylight Lamps” different from standard white LEDs with the same power? What gives them the therapeutic properties?
In: 17
Daylight lamps attempt to mimic the frequencies present in sunlight, and the balance of those frequencies. “White” LEDs don’t try half as hard (which is why you’ll find them labelled as “warm white”, “cool white” and so on – “white” covers a multitude of sins, basically). It’s as simple as that. My own experience with them is in art and crafting contexts requiring colour-matching, where you absolutely want a daylight lamp. Otherwise as soon as the lighting changes and you see your work in actual daylight, say, you’re likely to discover that your “matching” colours are visibly quite different.
