20 Gallon light help....

Ok I have a 20 gallon tank that I just started to cycle. I am in a major debacle as to what to get. One light I am considering is an all glass deluxe hood (believe it is 15 watt t-8) for around 40$. The other one is Satellite compact floresent single bulb (65 watt) for like 85$.

I have dabbled in plants in my big aquarium some and thought about doing a few in my 20. With the all glass hood would I have enough light for plants? It just a big price difference if it would work.....

Well, what kind of plants do you want? I have a 20g with a similar hood to the one you're looking at. Things like java moss and java fern do alright (the moss slowly grows, the fern simply doesn't die but doesn't grow much). However, anything that needs more light hasn't fared so well. I've tried hornwort, water lettuce and pygmy chain sword and none have survived. If you're interested in a really heavily planted tank with varieties that require more light, I'd definitely go for the compact fluorescent.

Here's a 65W compact fluorescent for only $72:
24" Aqualight (Fresh) 65W Lamp Str Pin (ESU)

Although, I've heard Coralife's quality has declined recently. The Current fixture (which is probably the one you're looking at - this one: Compact Fluorescent Aquarium Lighting: Single Satellite Compact Fluorescent Fixtures) is nicer and even comes with a lunar light, which is cool.

Also, here's a high output T5 fixture. The 24" version has two 24 watt bulbs for a total of 48 watts. It's on sale for $68 which is a bit cheaper than the Current compact fluorescent fixture.

Yeah the middle light is the one I have considered! That will put me at 3 watts per gallon, which I figured wouldn't be too bad. I don't have a specific plant in mind, I just want to make sure that I have enough light to attempt to make something grow lol plants or algea! Thanks for your insight iamntbatman

Yeah, with lights its all about they type of plants you want. 3 watts per gallon will let you grow just about anything but the really high intensity species.
