Hey man I live in England , I bought the Hagen t5ho over head lamp , got it from zoo plus.uk , they do a 2x24 watt or A 2x39 watt , I have the 24 watt and I only use 1 bulb over my 30 gallon and it does the job very well , you could quite happily run 2 bulbs if u inject co2 , I did build my own hood to work with it
, it clamps on to either side of the tank . Hope this helps
