Recently purchased a bunch of 4' 2-tube T8 flourescent lights for the paint booth in my workshop.

I've been fighting a losing battle with old age and have surrendered to the need for more light. The space is about 6' deep and 12' wide. I had it lit with 6 75watt reflector-style (PAR) lamps like you'd use on the eaves of your house. Not the best of situations - lots of heat and even flood pattern is too "spotty" at these close distances.

The new lights are narrow with a plastic lens of the same "diamond-like" pattern in office lighting the world-over. The lenses are U-shaped.

On occasion, spraying a large object will result in overspray being directed towards a light.

I would like to cover the lenses with some easy to replace plastic so overspray isn't an issue.

Any suggestions?
