would this work

[gman52]

i have a 20 gallon tank. for lighting i have a total of 40 watss NO lighting. i was looking at MH, and its over 200 dollars. and at home depot they have a MH spot light for 120. would that work? im prob wouldnt get it any time soon. but down the road, would it work? by the way, the MH spot light is 70 watts

you can find a used light that is made for aquariums for less than 100 ...
save your $$ and buy one of those.. check other forums.. with a selling area
