My 1-128 Sylvania has the standard 12VP4 instead of the 12VP4A so background lights ruin the contrast unless you keep the lights very dim. Incandescent lamps are a problem, but CFL and fluorescent lamps are the worst. They all produce some near UV and deep blue light. It seems that it makes the CRT phosphors fluoresce.

I recently purchased some Philips 75 watt equivalent AmbientLED LED lamps. They have no UV and produce a warm light.

To my surprise, even with the lights at full brightness, I get good contrast and am no longer bothered by the room lights when I watch the set.

I don't know if the results would be the same with other sets but I thought I should mention my experience with the AmbientLED.
