Quick test of the Medialight Pro 6500K CRI99 Bias Light strip

There certainly is some borderline UV, but the actual energy even at the 400nm peak isn’t very high, especially when used in its intended purpose behind a tv and bounced. If you’re worried, then you probably have your curtains pulled closed during the day as well

Here’s the spectrum compared with and without polycarbonate saftely glasses to block actual UV. Doesn’t affect CRI.

Two things:

- Why a bias lighting has to use ultra high CRI like this? AFAIK the purpose is just to make our eyes adapts better between the bright screen to the dark surrounding. Unless it’s bright enough to be useful as a room ambient lighting then ultra high CRI will be very useful. Is it bright enough for room ambient lighting when not in use as a bias lighting?

• Those polycarbonate test is very useful if we want to use the growing popular violet/purple pumped LEDs. Especially those used in the museums. You don’t want to faint a Monalisa painting with UV/violet/purple/etc… LEDs.
