I've used back lighting for years on both my sets, using a 20 inch and 15 inch flourscent with a 5000 k (sunshine bulb from GE, full spectrum light), got it all at Walmart for less than 20 dollars, (bulb you must buy separately but they have it there. I like the halo around the TV, but the best thing is you can turn off all your other lights, and not get a headache from watching in the dark. Apparently your eye gets very strained from the constant light to dark to light that is constantly happening every minute when watching at night. I had built-in TV viewing areas built into the wall when I had my house built, so I was able to get a nice boxed in light effect with both my TV's, but my Dad just had a big entertainment center, and we just put the light on top with a switched cord by the front of the TV to turn on the light. This works great for him because he just has a 36 inch non-flat screen TV, which would pick up all the glare from any lights in the room. I think you can get a screw in nature or sunshine light at 6500k at Walmart, and I believe at Home Depot and Lowe's. I suppose you could just try a regular bulb in a small lamp behind your TV just to get an idea of how it would look before investing any time and money. but to get the full benefit you would need a flourscent with at least 5000k, 6500k is best, Natural or Sunshine light (full spectrum light). I'll try to take some pictures if I can get the right exposure, and post them.
