light rail -- sort of
 

so I had one pendant on top of my frag tank, with in the middle lots of light and on Bothe sides a fair bit that fel out of the main beam of light.

I had a microwave motor kicking around and made it to use.

I attached a 6 inch disc on it and some braces

now it swings 6 times a minute from, 3 inches to the left, and 3 inches to the right, including the wiggling that happens during the swing, the entire tank gets a full beam of light.

sps in the middle and lower light demanding frags on the outside, its not fancy, but works great !!!
