Ambient background bias lighting - does it make a difference?

[frank_t]

Hi folks -

I recently purchased a 6500K backlight to mount behind the TV. The set is a 46" XBR4. The light is about 24" I think and has a baffle on it to adjust the brightness.

Anyway - was curious how people have mounted lights behind their sets. I can certainly velcro it to the TV, which seems like the best choice at this point, but curious what others have done.

thanks in advance.

Here's what I have:
