Is this a good fixture?

I have a 20 gallon FOWLR aquarium. This is an LED fixture that I want to get. Is this dependable?
BeamsWork Freshwater Bright LED Light Fixture 24"

 

link doesn't work, but if its FOWLR, it doesn't matter a whole lot, just try to stay away from "grow lights" and white heavy lights due to algae issues.

 

What if I use an 18" fixture with an aquarium of 24" long?

 

For a fish only system, any light will work man. Any light. flashlight, clamp light, floros, sun light, those leds, its not doing anything but making them viewable by you.

 

+1 true

 

+1, I agree.

 

So is there a cheap LED fixture that any of you recommend?

 

If you are going LED I would put a little more into and get a rapid DIY kit. That way if you ever decide to get into corals you already have the light and wont have to buy another. Just save you a little $$ in the long run

 

Marineland does offer a fixture that is pretty cheap and would work well with FOWLR but would never suggest it to grow a lot of corals

 

The reef version of what you were asking about is what i use with the 18 1w LEDs. (http://www.aquatraders.com/LED-Reef-Bright-p/56212.htm) this sits over my 10 gallon and is supporting my soft coals just fine. Since you just have fish and rocks and apparently don't plan on corals then just get the fresh water version on aquatraders. It is around 35 bucks and you can see it here: http://www.aquatraders.com/LED-Freshwater-Bright-p/56202.htm That would be a cheap LED fixture for you.
