So, my current light is just a double 4foot t5 thingy(2x54W), just like one of the ones that are attached to ceilings, not aquarium ones. But the tank is only 110cm long, and im making the hood so it doesnt stick out :-?
Is there anything wrong with cutting down the unit to hold 2 3foot bulbs(or are there any sizes in between?
Or is the 2x54W ballast going to be unsuitable for smaller Wattage bulbs?
So Can i cut down my t5 unit to fit a smaller bulb?
