Can anyone tell me what the actual length of the 31W T5HO bulbs from Coralife is? I know they call them 30", but I need the exact physical dimensions.
I'm working on a custom 3xT5HO fixture, and I am wondering if I can fit the 31W bulbs in it. I'm using a case from an old Odyssea fixture, which measures about 29.5" long. The light is going on a 29g, about 30" wide. The problem with 24W bulbs is they are too short and leave the ends of the tank too dark, so I would love to install the 31W bulbs.
