I found this light at a garage sale a few years ago and tried using it on my tank, but it just made my tank get over grown with algae. I was wondering if anyone knew anything about this light and if there are any bulbs that they know of that could fit this fixture so that I can actually use it for my tank.

The Model is TU200 and it says the Lamp type is F13TT. Any info/suggestions would be greatly appreciated!

Teknion Portable Magnetic Lamp, Model TU200. 13 watts.

Chances are the bulb the previous owner put in is warm white or cool white, neither of which is a very good spectrum for planted tanks. I'd try something like this:

But as it induced algae so strongly, I suspect it's too much light for your tank, or enough light you require Excel or CO2 - plus maybe other ferts as well. What's your tank size, and how do you have this light mounted on it?

It was on my 10 gallon tank, which was probably only filled with 8-9 gallons of water. It's one of those standard 10 gallon glass tanks. I had it resting on top of a DIY cover made of plexy glass, so the light was shining through the plexy.

All i had in the tank then was an anubuas that had no light before, so I gave this lamp a try since it was only $5. Suprisingly, that anubias is still alive and slowly growing after almost 2 years w/o any light on it.

Do you think this lamp is complete overkill for that tank?

Hmm, not too much for the tank overall. But with the tank almost twice as wide as the fixture, and the shape of the reflector, I think you have too much light in a portion of the tank, directly underneath.

See if you can rig up a way to raise it about 5". This will improve light spread, and probably give you a low light level overall, but I think it'll still be enough for anubias.
