Where did you get yours? Any tips on which to buy?

I've seen this recommended a couple of times, but I wish I could find something cheaper:

cinema quest inc

I have a Samsung LN52B750 if it matters. Just looking to improve my night time blacks! I have very very minor flashlighting on the bottom two corners, and i was hoping this would help in that regard as well as making blacks appear a bit blacker. If not i really dont mind, but it would be nice. This is what they are for, no?

thanks everyone, happy holidays!

Although $59 may seem alot, its actually worth it, the Bias color is just right and its slim and easy to install/setup.

It's always better to have more than one because (depending on the type you get) the light distribution might not be as great as you'd image and so one area of the television may appear lighter than another side. I have one with 4, and it did take me awhile to figure out where to put it and have the light symmetrical.

A few good photo's on this

Sorry for the horrible quality images.

I bought a really cheap rope light from Wal-Mart. Cost me $8 I believe. It does wonders for my black levels. I attached it to the back of my 52B750. Blacks are PLASMA-LIKE with the rope light.





This is a temporary solution (the light is attached with clear duct tape until I can find the proper tools to mount it right).

This is a REALLY cheap solution, as I don't have the space and money to spend too much on a truly great setup. It's in the bedroom with very limited space, so excuse my poor excuse for a setup. XD

BTW, the rope light also comes in blue and red. The white rope light is pretty yellowish in nature as you can see.

thanks for the pics shin.

im seriously considering going that route, since it seems so easy to set up and its really cheap.

i definitely dont want to spend $120+ on 2 standard ideal lume lights from cinema quest. im probably going to a couple hardware stores tomorrow and seeing if i cant find some 6500K fluorescent lights.

Using white dimmed light behind the tv is already a big improvement over yellow light.
Having black/dark coloured walls in your tv-room is also a big inprovement.

So, for those of you that have come up with your own solution, I will assume you have it plugged into the switched outlet on the back of your AVR, correct? But, if you want to watch tv without using your audio setup (through the tv speakers), how do you turn the light on and off wothout getting up and replugging it into a regular outlet every time?

Take responsibility for your own actions...society is not here to look after you...
In other words, if you order coffee, expect it to be hot for chrissake!

Planning to control mine with this IR remote control outlet which is on order:

I have a programmable universal remote and will add control for it as part of the power on and off macros.

If you aren't viewing critically just watch the TV as-is w/o the back light. For serious viewing fire up the A/V system.

For my Old Rear Projection TV I may just get a regular 4' single lamp T8 fixture and mount it on the back of the set. Get a "sunshine" 5000K 86CRI lamp for it. Easy an cheap.

What color temp of light is considered correct for a bias light? I recognize that the color of the wall will greatly affect the light color reflected back to the viewer, but assuming it's neutral gray, what color temp is recommended?

Something like this may work for you...
I'm not sure about posting Amazon links but just copy and paste this...it's a power sensing power strip

I did the rope light trick on my B750 as well. Some white LED ones are bright and clear as hell. $20 bucks for 12 feet. Secured with clear zip ties which were included. Yeah, the rear doesn't look professional or anything, but nobody looks at the rear of your TV so who cares? Takes a lot of stress off your eyes for late night viewing.

Of course, I got it modified with the TK-427, which cheeks it up another, maybe, 3 or 4 quads per channel.
