    Jim, I'm VERY skeptical of those kinds of anecdotal tests, having constructed numerous fluoro tube lightboxes myself. Getting truly even diffusion is actually tricky. Maybe Bob S. will weigh in on this too. Of course, that's just an analogous case. Sandy K. has made some more detailed comparisons of UV tubes per se.

    Insane advice with never a picture proof is worthless

    With fl tubes the eve ness of illumination is also dependent on the distance the tubes are from the diffusion surface.
    Kaiser slim boxes had to have a silver stripe, the length of the tube, to even it out as the top of the tube was so close to the diffuser you would get visible banding without that stripe.

    Thanks Bob, that would be easy to implement

    I also have Makrolon LD IF needed, it was designed for LED diffusion

    LED diffusion? Think "rim lighting" rather than head-on diffusion. Don't worry,Tin Can, I'm just waiting for retouching station to warm up, and then I'll disappear.
