i use 6 100watt( 26 watts each) on a 29g tank to get medium high light and i have a reflector.
its alot of light but i wanted higer lighting, if you want low light the 4- 26 watt bulbs will be fine. youll be gettin around 1.5 watts per gallon with the 4 bulbs on a 55g.
these bulbs arent actual 26 watts because of there shape, you loose alot of light with there shape. there more like 20 watts each bulb
