Bulb Fixture Plant

Does the watts per gallon rule applie to T-5 bulbs?
Okay, I have a 30 gallon aquarium with a hood that can fit one T-8 fluorescent bulb. Now I want live plants for it, low to medium light plants. So I ovioulsy need more watts. Now, I've heard the watts per gallon rule applies to T-8 fixture, but what about T-5 fixtures? I know T-5 lighting fixtures produce more Lumens per watt. So would a single 24 watt T-5 be better than a single T-8 20W? I'm going for mostly medium light plants... Would that do, a T-5 fixture for a 30 gallon aquarium, 24W?
Even for low light plants, you should aim for a minimum of 1.5W/gallon; if you are under 1W/gallon, just hope for the best but don't expect much. Some things like Java Moss and perhaps top-floating Hornwort might grow.
The T5 shape gives you SLIGHTLY more directed illumination per photon. I think I remember roughly +15% illumination compared to T8 at same lumen rating, in some person's photometer tests. The reflector, water clarity, and cleanliness of the bulbs / acrylic shield are just as important, though, as the choice of T5 vs T8. And T8 tends to be cheaper, for a low-light setup; it's just harder to pack much more than 2xT8 bulbs above a tank.
You really need a double-tube (whether T5 or T8), or power compact light, for even a low-light tank. For medium-light plants, I would suggest a minimum of 2.5W/gallon to try to grow a nice bed of whatever strikes your fancy.

witch light fixture and bulb would be good for a 29 gallon fish tank ?
now i have live plants and want to breed fish so i would want to know
what type of bulb would be best to hold many plants for them to grow
plz include pricing and site if any thank you very much for your help
www.liveaquaria.com
if you search through the articles on lighting and such you will find way more detail than i could give. They make bulbs especially for plants such. Probably the more light the better in this case.
I would look into power compact lighting.
Its all there on the site.
