I picked up this Kotobuki tank and light fixture for real cheap. Got it all set up, it looks and works great.
It's got a 2 light fixture with individual ballasts and switches. I have flo fish and some neon tetras, so I'm thinking throw a blacklight in one of the two slots and I'm good. Well, not that easy.
This Japanese kotobuki stuff is a mess. I think I'm going to have to do some work and adapt it.
I think the bulb is Sanrukku (32W) based of of the markings and measuring the bulb. The site is in Japanese. Goggle chrome translated for me, hopefully you have that too.
830mm long, 32.5mm diameter, I THINK
G13 bipin, though I can confirm that relatively easily.
There isn't room in there to go to a 36" bulb, so I might have to put two bulbs in series or something. I don't know, I'm looking for some thoughts if anyone has run across this before.
