Light type reccomendations?
Hey everyone,

I recently found a supplier of aquarium products here in australia, that sells products around 1/2 - 1/3 cheaper than LFS's do, and I was browsing their lighting for my 4 foot... They had a vast variety of lighting types, and was wondering, what lighting is best suited for a heavily planted tank? eg. t5, t8, metal halide, etc.....

Thanks in advance!:thumbsup:

Metal Halide is overkill for a freshwater planted tank. It's primarily used for saltwater high lighting corals when you need the light to penetrate. Florescents are your best bet, so long as the wattage is sufficient and the bulbs are in the 10k to 6.5k range it should be fine. Go with what you prefer.

One big question more experienced plant people will ask though is what kind of plants do you have. Some can survive and thrive in low light others need intense lighting.

You want to avoid T12 or T8 lights at all cost. They aren't as efficient, plus they're sort of going the way of the dodo so finding good bulbs for them will become increasingly difficult. T5 is a better bet, but I can see T5 going out of fashion not too far in the future. The most bang for your buck and best investment for the future would be compact fluorescent lighting. It's a lot more efficient than regular fluorescents and puts out a lot more lumens per watt than even T5 lighting.

I decided to get a t5 H/O lighting system. But i'm just wondering, my 4 foot tank is 24 inches deep. Will the lights penetrate that far down? The bulbs are full spectrum, 54 watts each, and there fits eight in the fitting... That equals to 432 watts. Is that, or is that not good?

120 gallon tank? Should be fine, 24" is not that deep and plants will not stay exclusively at that depth. That should give you plenty of light and let you plant whatever you want in the aquarium for the most part.

Lol, I wish 120 Gallon. It's an 80 gallon.
Sweet thanks for the help!
