This is pretty embarrassing but I gotta ask. My 90 gallon has a 48" fluorescent fixture and bulb in it. The bulb is the bigger kind with two pins on the end and its the thickest one. What are these bulbs designated as ? Beyond fluorescent so I know what to order. I got a new lighting setup coming for it soon but the bulb for my old 48" died and I want to get a bulb for it so it can be used on one of my empty 55's
So my question in a nutshell. What is the old old standard fluorescent bulbs code name or trade name so I know where and what to order. The ones at the pet store seem a lot skinnier than the bulb it was running before.
I apologize my expertise is in HVAC R sheet metal and HPS and metal halide lamps for obvious reasons.
Thanks for any and all help folks.
