Would these work for a DIY hood application? It seems like you'd be able to take apart a standard one bulb flourescent strip light and put in sockets to hold these. That way I could use my "standard" canopy I have now and not have to builda whole hood which probably owuldn't look as good. and at 45 watts a piece, it seems like 4 would suffice for a 55 gallon tank.
 
Thanks for the reply. Since you can get light sockets for about $1 each at the hardware store, with a little wire and electrical tape I think this could be cheaper AND better looking than the shop light solution. plus it would fit neatly into my pre-existing cover. and I'm all about cheap :D

Any other thoughts?
 
seems to me like they should use the same phosphors in the compact spiraly "daylight" tubes as they would in the big "daylight" tubes, so seems like they should work the same as those. probably not as well as bulbs with phosphors specifically designed to grow plants though. I'm not an expert in this area I'm afraid. But with 4... seems like they're 45 watts each, so that's 180 watts over a 55. more than 3wpg. So if you figure in spectral inefficiencies and I'm sure the ballasts are inefficient... I'd probably be getting the equivalent of 2wpg of "good" lighting. I don't have a lot of cash and don't expect to for several months, so I think I'll go with this idea for now and keep you posted on the results. If all else fails, I can probably convince my parents to buy the bulbs from me and recover my losses:p
 
If you manage to get day light spirals then that is even better. I use them in a 10 gallon and 2 5's as my hood came for incandescent lights. They are fine at growing low to moderate light plants.

The one problem with them is that they are much less efficient than a standard flourescent buld. Since they have way more surface area they throw light all over the place. That means working on a good set of reflectors.

If you are buiding from scratch it isn't too hard to rig up a flourescent ballast.
