I have a 20L x 18W x 18H tank, roughly 30 gallons. I am looking for a new light. Most of the lights I see are 2 x 24W T5 HO. Is that enough ? There are also a few LED light fixtures for around $120. Are they a good fit for my tank ?

Like this one : http://www.marinedepot.com/ps_viewi...&utm_campaign=mdamazoncpc&utm_content=AS32991

Suggestions are greatly appreciated. I need to order the fixture today, as I need to return my current light to my friend who "gave" it to me :)

i have a 2x24" T5HO light fixture on a 18 inch cube and the light is not strong enough to penetrate to the bottom. plants near the top have good growth but plants closer to the bottom are really straggly and leggy.
