cf bulbs

I use Cf over my 20 and they are great...I had to make a fixture to 
accomidate their larger size.  I think that the smaller ones (like the 9 
watt, would fit into the incandestant sockets of an incandescent hood (at 
least this is what I am going to try next :)  Two 9 watt bulbs aver a ten 
would be adequate light for a ten gallon...but would be pretty inadequate 
for a twenty.  I have two 28 watt CF over my 20 and it is like daylight..I 
love it and so do the plants, judging by their O2 bubbles that they are
