Fixture question

[DesignsOnYou]

Has anyone heard of or used this fixture? It's available with free shipping on eBay for $100 and seems like a really good deal, but I just wanted some input. It would give me about four WPG on my 55-gallon, which will be planted. Thoughts? Suggestions? The seller says the unit is made by MHS. Thanks!

I'll be the first to admit I'm no plant expert but I think that may be extreme over kill. Again, I'm prepared to be wrong but I think CO2 would be needed for the plants to utilize that much light. Not to mention growth *may* be crazy fast in that case.

Hopefully someone with a bit more experience sees this and can confirm/set me straight . 'Cause I'm curious too.

It sounds like a good deal, but I'd be worried about getting replacement bulbs. T6 isn't terribly common, so getting replacement bulbs could be an issue. I think it would work fine for a 55g tank.
