    I was told to put a source of light behind the TV to improve the image. The description came in terms of temperature (e.g. 6500 degress). In lay man's terms, what kind of light is this? Fluorescent? Incandescent?

    Hi Bob,
    Most find and use the flourescent type which are not easy to find. More info here.
    Thanks,
    Errol

    I found the flourescent at a PETSMART. They are very popular with aquariums. The pacaking will indeed say 6550K.

    Any fixture for an 18" bulb will do the trick. I just velcro'd mine to the back of the set. Let it shine on the wall.

    I was able to find a 6500K flourescent bulb at Home Depot that screws into a standard lamp socket recently. Its labeled Daylight and works well. I put it in a small 'can' light fixture. I think it was $6.99.

    The probelm that I found with so called "daylight" bulbs is that they are not 6500k. We actually took measurements with the analyzaer.

    The one I purchased said 6500K on the box and bulb. I also have seen many 'daylight' bulbs that were not 6500K.

    This was the first one I have seen that is clearly marked as such.

    Home Depot sells the Philips Daylight, namely the F20T12/D. Only problem is that it's only 74 CRI (90+ is recommended) and I couldn't find it any shorter than 24". I use this for a 32" wega and if you sit on the side couch you can see the back light. Try getting an 18"er if you have less than a 36" set and have side seating.

    Might I suggest turning out the lights and watching in the dark? I find the backlights distracting in the extreme.
