Simple backlight for close backlighting situation

[celtics23]

I'm in need of an inexpensive backlight for a 3 point lighting setup. The setup involves the subject sitting in front of a 70" flat panel television, which makes up the entire background. My thought is to place the backlight on a simple light stand right behind the television screen.


Both the key and secondary lights on the subject are very white color temperature, so I'd like something to match. The backlight will only be a couple of feet from the subject, so I don't want something too strong or otherwise inappropriate for this setup.


Are there some suggestions people could give for the backlight I should use?

What do you mean by "very white color temperature"? for your main lights what do yo use?, tungsten, LEDs, fuorescent?, do you use any kind of temperature control gels?

[celtics23]

5600K color temperature. Key and fill lights are fluorescents without temp control gels.

Pros around here would probably consider this:

an inexpensive and simple soluition, and you still´d have to buy a proper light stand, barndors and proper color color temperature correction gels (not to mention spare light bulbs)
But for something really inexpensive, you could get away with something like this:

i'm considering the pro light. i don't work much with tungsten. am i correct in thinking that those emit UV radiation and i'd need to filter it to block that?

The film and video/TV industries have used tungsten lighning for many years. Do you mean this?

maybe I didn´t understand your question.
Anyway, if you go for the Pro light, you´ll need a blue color correcting gel to match your other light sources, and a good one will absorb it
