Im interested in back lighting my 100" projection screen with blue light. When I say back lighting, I mean keeping the screen off the wall about 1.5" and having a blue glow emanating from behind the screen. I was wondering if anyone knows the best light source to use. Im thinking of blue 120v rope light, any suggestions?
Thanks

You should be able to do that with rope light. Just add a dimmer so you can get the brightness tuned in so that it's not a distraction.

Careful with that, Cathan. Standard Home Depot type rope light will buzz (noisily!) and flicker unpleasantly when dimmed. You have to go to higher end rope lighting to avoid that. I know a lot of people on here have used rope lighting from a certain online store. 1000bulbs.com or something like that, is it? Hopefully someone else can chime in with the appropriate URL.

Alternatively, you might consider using incandescent lights and putting blue bulbs in them, like Ruben did in his SandmanX theater. It looks like this:

attichometheater, are you talking about bias lighting while a movie is on? If yes, then you can easily do what Cathan states. Drin's post of Sandman's lighting is cool, but its obviously pre-movie. Drin, the url is correct, the specific link to their rope lighting is:

I have not used them, I've bought two 150 ft spools from Noveltylights.com:

Something like this, but with a blue light?


I bought my blue, dimmable, LED light from:
http://www.cbconcept.com/LED120vRope.htm

Not that fanciest of website, but they sell it in more managable sizes and the price is better than some other sights.

I like the idea of this thread. I too was thinking of adding pre-movie accent lighting to my movie screen. As others have stated, it would need to be dimmable, not cause noise to the line....I would need to find power cords that were black..so it would blend with my black screen wall...can one spray paint a power cord without creating a fire hazard or compromising the integrity of the cord?
