I'll have to post the pic later - still use a film camera and gotta get it developed first
Basically, you'll find the plastic channeling close to the ropelight in the lighting section of H.D.. It is a plastic "U" that the ropelight slides into, and is around 8 to 10 feet in length, easily cut-to-fit. The bottom of the "U" has an adhesive strip to attach to whatever you are placing the ropelight to. Not to worry - the adhesive strip comes off cleanly - no residue to worry about if you decide later to remove it.
Warning though: I found that the adhesive wasn't strong enough for this application. I also didn't want to mar or otherwise damage the back of the plasma, so I used Krazy-Glue between the adhesive and the plastic channeling - it worked like a charm and no damage to the set at all
The pre-length of the ropelight is around 6-9-12 feet depending on what size you want, so better measure the back of the unit before you purchase. I installed mine just BEHIND the leading edge of the back of the bezel, about in ch or so down. Nothing shows at all from the front of the unit. There's a rather short electrical cord with a mickey-mouse on/off switch. I supose you could plug it in so that it came on automatically when powering up the entertainment system - I'll look into that later.
Don't know if the interest is there, but I also wanted only ambient, reflected light when watching movies. You know, just enough lighting so I wouldn't trip over one of the dog's toys, or otherwise stubbing toes and doing a "Fred Astaire" across the room, arms pinwheeling along the way. So, I installed ropelight around the entire perimeter of the room, at the baseboard level. We live in an old house, with 8-10 inch high baseboards. I had to go up and over a couple of doorways, as well. I ended up getting a Dimmer switch , plugging the ropelight into that and then plugging the dimmer into the wall.
Now, I "slide" the dimmer switch from hi to low, in concert with the roaring of the lion at the start of the movies. By the time the lion is finished, the only light in the room is a faint glow from the perimeter of the room and of course, the backlighting from the plasma.
You know, for a lousy 10-spot, that dimmer gets the most laughs and attention at the beginning of each film!!
Go figger, right?
