Hanging Light Fixture Questions

[ThePBM]

So I've got floating plants that are growing above the waterline currently, say, 7 inches above the top of the tank.
It is an open top, all natural tank, and the plants are pretty much almost touching the light bulbs themselves.

My question is- if i suspend the light fixture (it's a standard shoplight) is there a way i can still direct light just into the tank without having light splash the whole area?

All i've thought about so far was like hanging something like short curtains along the edges of the shoplight, but if anyone has a design for altering the reflector to focus the light, that'd be a lot prettier.

you can get a roll of aluminum in hd and make a skirt for the shoplight. Can also spray paint it for looks.

Looks something like this, if you decide to get it

ofcourse some have them at different heights and the length is around 10feet or so if not more, I think a 6-10" skirt would be perfect

is that like ducting aluminum? is it expensive?

 

[Bk718]

forgot exact name of that aluminum roll.. but its around $8-10 for a 10' roll

It's aluminum flashing, was around $10 for 21"x10' roll in home depot.
