I'm considering upgrading the lighting on one of my 55 gallon planted tanks from 2X54 to 4X54 T5HO. I need some help finding the parts though. It's currently a wooden hood that the previous owner mounted two reflectors/holders in. It works well, but there's some plants I'd like to try that need a little more light than that. There's not quite enough room to mount the extra two single bulb reflectors/sockets, so I'm looking for a 4 bulb reflector and a 4 bulb socket set. Since I already have a working two bulb set, I'd like to reuse what I have to save a little money. Plus, I like the idea of being able to switch off half of the lights if I need to. I'm already planning to use one socket for an actinic bulb to bring me to 3wpg instead of 4. So, does anyone know of a place where I can find the reflector/holder? I found a few retrofit kits online, but they're more expensive than an additional 2 bulb complete set....
