Default Flourescent Light Diffuser Bump Map?

Anyone have a good tileable bump map for a prismatic flourescent light diffuser? I need one for a project at work, and there seems to be a severe shortage of images online of flourescent light diffusers taken normal to the thing. We use them in a mold here at work to make a non-skid texture, and I need the bump map for rendering some images of the finished product.

If you were to model a piece of one... Its just little pyramids basically, then take a gradient going from black to white and planar map it down X or Z in luminosity. Hit autosize to stretch it out to fit exactly. What you'll have is the white mapped to the high points and black to the low points. Then just set the camera to ortho and size it to whatever res you want. Kill the default light and render. You'll be left with a tileable bump map. Its harder to describe than it is to do.

Knocked one up quick. This should do but you'll need to crop it a bit in PS to get it to tile right.



Here is the scene and object if you want to fiddle with it some more.

Diffuser.7z
