Does anyone know where I could find T12 actinics? I've got limited space, so the bulbs and end-caps can only take up about 18" x 4". I'm not even sure if such a product exists. Maybe T8?

Coralife and Phillips make T12 Actinics. Your local fish store should be able to get the coralife for you and any lighting store should be able to get the Phillips.

I don't think you will be able to fit any in that space though.
You may have to look at PC retros or small T5s.

IPZ, thanks for the lead. This is what I found:

It won't fit, though. You're right, muck. Too bad Coralife doesn't just make actinic screw-in bulbs. The 50/50s are pretty good.

I picked up a $20 18" T8 black light at Home Depot today, just to see if it would fit, and to see if it would fluoresce my tank at all. I put the bulb in my $10 plastic 18" fluorescent strip light that I also picked up at Home Depot awhile ago (they still sell these cheapo plastic fixtures).

The bad news:

The 15W black light doesn't have any effect on my tank against 108W of daylight bulbs.

The good news:

1. I can return the bulb.
2. The strip light fits under the lid of my canopy - just barely.
3. The strip light takes 18" T8 bulbs.

It looks like I'll be able to add an affordable actinic light to my tank after all. Here's my next question:

Will a 15W actinic bulb noticeably offset four 27W daylight mini-compact fluorescent ("spiral") bulbs?
