I am working to start a low tech planted aquarium without C02 generator. Based on this http://www.sudeepmandal.com/hobbies/planted-aquarium/low-tech-planted-tank-guide/#advantageslowtech article.

Question about CFL bulbs. I have a really nice hood which uses the screw in type CFL bulbs. I have noted that there are also other types (long rather than spiral) and want to be sure what I am planning will be OK. 55 gallon aquarium, three bulbs in the hood, use 45 watt bulbs which will be a yield of about 2.5 watts per gallon, the highest recommended for the low tech setup.

Please advise on the bulb type.

I agree with DeChaoOrdo except; I figure my WPG based on the fluorescent tube output.
For instance on my 46g BF I have a 96 watt cfl tube. So I have approximately 2.08 WPG.
It is actually less than that because of substrate/driftwood, etc water displacement.
By far the best measurement is a PAR meter.
