Backlight for Home Theatre
I read somewhere backlighting or "bias" lighting really takes the strain off your eyes when watching movies in a dimly lit room.
Is this true?
And where are the best places to get them?

Yep it's called a Bias light. It makes it more comfortable watching a movie becuase it's easier for your eyes to adjust to the light and dark scenes in a movie.
You can make one yourself using a fluorescent bulb, but the trick is finding a 6500K bulb.

$45.00 seems a bit high!
Your local hardware store probably sells the 18" long lights and 18" "Natural Light" 6500K bulbs for about $20 for the pair.
I already had an 18" black light and all I had to do was replace the bulb with the 6500K one for $5.

Note that a bias light doesn't work for a RP, but works best for direct view.
Funny thing about that, my mother always used to tell me that watching tv in the dark was bad for my eyes.

I bought a 1.99 string of lights last xmas, blue, and have been using them as a backlight. (I ran it all around the back of my entertainment center).
The result is rather cool, it's like the thing is glowing blue. It's just enough light to keep your iris from closing all the way down... and the blue keeps it from being too strong if you happen to look at it directly.
High temperature lighting is better, I'm sure, but this is cheap and wicked to look at.

All you really want to is light the wall and area behind the tv to reduce stress on your eyes when the tv shifts from light to dark scenes

Unfortunately since it is a flourescent I can't just hook it to the switched outlet on my Panamax.
It will turn off, but won't come back on, so I have to reach behind the TV everytime I need to turn it on. Luckily it isn't that hard to do in my setup!
I really never got into it that much. Alot of times I don't even use it at all. I usually only watch one movie at a time so my eyes never really become that tired

The one I use is an older blacklight(with a 500K bulb of course) with a rocker switch on it, maybe I should go buy a new one.
I do like using the backlight since it keeps me from smacking my toes and tripping over things when I get up to get a beer

How useful is backlighting?
When I move into my new apartment I think I might attempt to backlight my tv. However, I was wondering how much of a visual benefit this truly gives? Anybody who has tried it both ways know how much strain backlighting saves on your eyes? Does it distract from the dvd?

Never heard of this myself, so thanks for asking it again.
Scott,
Not sure if you're still around, but I was wondering why this doesn't work for rear projection sets?

I have to agree with DVD-O-Rama. It works great on my RPTV. I have it velcroed to the back of the RPTV and lucky enough to be able to plug it into the outlet that is controled with the light switch.It helps out your eyes alot but only at night . For the people that bought just the 6500K bulb at Home Depot .What bulb was it I have had no luck there and the salesperson have no clue what I'm talking about.
Thanks
Thanks

Here's an option for people who want it to turn on automatically with your TV:

Finding a 6500K bulb at your local hardware store is not that easy... The best that I could do was a 5000K, so, that's what I'm using at the moment... And, yes, it reduces eye strain on RPTVs, dunno where the idea came from that it does not... This has been covered in pretty good depth in the "other" forums, you know the ones, and it is indeed a very good idea... Also adds to the whole experience, IMHO, and provides a nice low ambient lighting for your room with no worries of screen glare. I have mine (18" variety) mounted on the wall behind my set.

I use a standard blacklight that you can get from Home Depot, Sears, Walmart, Target...just about anywhere....that was the advice I rec'd when I got my RPTV a while back.

My wife ordered one of the Ideal Lumes for me for my birthday, and I must admit that after using this for watching DVD's I was really impressed. The fixture mounts to the wall behind my TV(36" tube) and after adjusting my settings The blacks did seem blacker and there was no glare at all. The dimming kit really helped eliminate the glare (unfortunately my walls are white).Definately worth it in my eyes.
