I have a blue version. Aphrodite just acts like its not on. They arnt very bright at all

I don't think it's as much that they can't see it (at all) as red and blue lights do not seem to bother them like the white and yellow lights do.

Red lights keep our eyes from dilating...

Q. do all you guys prefer red? red hurts my eyes after awhile. i prefer green or blue. my car has the dome that's white and red w/ the toggle switch. i was thinking about changing it for a blue or green oneYou just maybe need a brighter red light, you may be straining your eyes with too little light.

A. Blue or green (being close to blue in the spectrum) light (http://en.wikipedia.org/wiki/Visible_light) will deminishes your night vision, red has zero effect on night vision. Your rods and cones are no different than any other human.

It's also why when you meet a car with bluish headlights or when you follow a police car running code with blues or why when you look at the pretty blue lights on top during a stop, even momentarily, it's spots you see when you look away and it takes a spell to get your night vision back. The human eyes are especially sensative to blue light, and will see it as brighter, and react by constricting the pupil.
There is even evidence (http://videos.howstuffworks.com/sciencentral/2674-eye-damage-from-blue-light-video.htm) that blue light can damage (http://www.sciencentral.com/articles/view.php3?type=article&article_id=218392616)the eyes.

I first started when we still used red lights on our cars. Yeah, at first the blues looked pretty, but I noticed very soon that they were more irritating and that my night vision was deminished with them. I'ld be more than just pleased if we went back to red myself, not nearly as hard on the eyes and I can see in the dark better, and if something is happening bad there's less chance a passing driver is looking away from them bright blue lights.

And now you know why subs and ships have red lights to use before a sailor goes out on deck at night. The pupils will not constrict with red lights...

my guess would be its probably similar to why red lights are used in a dark room for photography.

I also read the thread about red lights. I figured with as much money as I spend on my babies whats 20.00 I dont know if its just a coincidence or not. They came out earlier for 3 nights now, They play more,and seen to have better appetites. I'm going to keep track.

I'm new and about to get gliders myself; I hadn't heard that gliders are very sensitive to light (although it does make alot of sense). but does what your saying mean that they wont be comfortable in a room with normal lights? or if in the day time we roll up the blinds in the room? (only indirect sunlight of corse) I now know i need a red light for night thanks!!

hummmm, I think I will give the red bulb a try...
