Black Lighting what's this have to do with anything? I thought that black lighting was something installed in clubs to make things look WACKY and to have fun. :haha
Back lighting is a feature on TOSHIBA regza hdtvs that allow the picture to look brighter and more vivid. Before I had to turn it down to about 20 to hide the artifacts in the backgrounds of sd channels. Now I can turn it up to 80 and I still don't see the compression artifacts on any of the sd channels and the hd channels look even better than before. Oh and I changed the original post to reflect that.
