Default red LED lights for nighttime ok?

Is it true that the red spectrum isn't seen by (or doesn't bother) hedgehogs?

I was wondering if it is ok to have a normal cage light on a 12 hour timer but then have a strip of red LED lights for nighttime (was thinking of the strips used for under cabinet lighting that have color options). Then I would be able to see the hedgehog at night, albeit in dim way.

After getting 12 hours of light the other 12 must be absolutely dark. No lights.

Hmmm. I recalled learning that red light (not infrared) was not visible to most mammals -- that a red light would appear as dark to them. That is why red light is used on African safaris to observe nocturnal animals in the dark.
This got me researching...

Wikipedia (I know, not always most reliable) seems to support the above links by stating, "Today, most mammals possess dichromatic vision, corresponding to protanopia red–green color blindness. They can thus see violet, blue, green and yellow light, but cannot see ultraviolet, and deep red light"

I was hoping a hedgehog owner who has had experience with red light could share.

There's have been a significant number of incidents where hedgehogs are considerably less active when red lights are used. Don't forget humans are mammals too and we can see red lights.
