my light bar on the 55g uses CF straight pin bulbs. 21-23inch long bulbs with 4 pins. I am trying to locate 1 or 2 red spectrum bulbs to use in this tank. I recently put a finnex fugeray r on 2 of my small tanks and some of the plants are showing a lot of red. These same plants are bright green in the 55g. I've searched foster and smith, checked coralife's website and even amazon. I can't find anything, and i might not be looking for the right thing.

Suggestions?

There really isn't any red colored bulbs for compact fluorescent fixtures. You are limited to bulbs in the 6500-12,000 K range or actinic bulbs. I searched along time ago when I was using cf fixtures and nothing and I really doubt there is any available today since everything is going towards T5 and LEDs.

+1 I searched also and I do not believe they exist.

Edit: taping a strip of red LEDs underneath your CF fixture might be a solution.

There is a T5 bulb that has a pink hue that might work for you. Its found in aquarium fixtures a lot. It is sometimes marketed as a plant spectrum bulb, but IME doesn't do the trick for growing plants on its own.

Yes there is lots of options for red colored t5 bulbs but he's looking for a red colored compact fluorescent bulb.

I know you stated 'red spectrum', and agree with ua hua & OVT (not existing - i.e., something like a version of the T5 633nm red sun bulb). I think Jim (w/Catalina Aquarium) stocks a 'pink' 22" 65w 4-pin CF. I have no idea as to what the spectrum might be for that particular bulb, or if you would even be interested, but thought I'd throw-it-out-there anyway.
