I'm buying a 40g breeder fish tank, stand, filter, etc for 70 dollars.. I think it's a decent deal, but it comes with a 15W strip light, which is too inadequate for a planted tank. I'm moving all of low-light my plants to this 40g tank, So, I probably need around 2 WPG, but these light fixtures are really expensive!! Do you guys know where I can find an affordable light fixture for this 40g? I don't have any tools, so I can't do DIY's!
