Need help for upgrading light

[fishshl]

Finally, I can't stand my 15w for my 20G high tank.

I plan to upgrade it to 1.5 wpg ~ 2.0 wpg.

Are there any fixture like :
24" twin light strip T5, 20 w each.

Or 24" twin light strip T8 20 w each.

But from internet all I found are 15w each no matter T5 or T8. So I only can get 1.5 wpg. I am not satisfied with it.
Are these bulb all 18" ? Can I find any like 21" bulb with 18w or 20w output?

Another approach maybe I can try is

PC 1x65 50/50, I think.

But I don't know which is better. Please give me suggestion.

1x55w kit from Ahsupply.com It will give you the best light, and are easy to setup and install in a wood enclosure that you can purchase separately, or build yourself.

If not that, I would simply get a coralife 24" 65watt fixture, or head over to aquatraders.com to check out one of their fixtures.
