Right, mount the end caps and install the bulbs, everything is pretty much plug & play. You would probably need 46 1/2" bulbs to fit inside the canopy on a 75. Depending on the look you want, you might use a VHO Super Actinic with an Actinic White or a Sun. That would give you another 220 watts of light.
