RED LIGHT ?

I purchased a pack of 2x25 w light bulbs for my 10 gallon tank, and when I got the lights home. I noticed one was red, ?? can anyone tell me what that is for, or what I do with it. I put it on my tank for 2 days temporarily, but it did not look good, and did not give off allot of light.

I believe it's a different spectrum of light and will grow plants differently or bring out different colors in fish. Just my guess or it's a reef light.

It's a nighttime light, I think. If you have it on at night it doesn't disturb the fish as much and they act normally.

I think your right, I cheeked packaging and it does not specifically say what it is fore.

I thought red lights were for plant growth, aren't they a different specterum concentrating on the red end of the scale which plants use to photosynthesize, and also algae cannot use this light.

Plants use almost anything in the spectrum except for green and a small amount of blue. It's why they're green - they reflect the green light because they don't use it.
