Thanks to this forum, I spent some more money! Just ordered the Ideal-Lume Panelight for my LCD upstairs. I'll see if it makes a big difference or not and report back. Here at the Axiom forum, one of our favorite things is spending someone else's money.

Cree and Seoul make some high CRI LED's, but I'm not sure if they are also high temp. Apparently the phosphor technology has improved a whole bunch, because AFAIK it is still the same yellow phosphor over blue die. I know some of the newer stuff can put out 120+ lumens with a little over 3V and 400mA or so. Oh, I wasn't thinking about that LED technology. They are UV LEDs which then excite a phosphor coat. So they are basically florescent bulbs, but with a diode junction instead of a discharge arc creating the ultraviolet light. With a good quality coat, they could indeed be high-CRI.

Here's an article that showed up recently where someone put lighting around a 110" screen: http://www.electronichouse.com/article/theater_images_pop_on_floating_screen/It wasn't designed specifically as a bias light, but for looks. It does look nice. If the area around the screen was painted a neutral white, and quality bulbs were installed, I think that would work well.

That theater looses points for having a Monster product in the rack, but he breaks even for that screen.

You know this thread has made me realize that I sort of made the same discovery as you, only accidentally, and not exactly in the same way. You see when putting together this room we put track lighting all around the room. Well when it's movie time we turn the center 'pot lights's completely off, but I prefer to keep the track lighting on just slightly. The walls are an off-white color, and I don't know the temperature of the track lights, but they create an effect similar to the environment you discribe.
Because of the way my screen is forward from the main wall about 4 feet, and the track lighting is directed at the walls on either side of the screen, it basically creates this effect in a round-about sort of way. Like I said it's not exactly the same, but similar. I've tried turning all of the lights off during movies, but for the most part I do prefer having the track lighting on low. I've never noticed that it might create better/deeper color saturation appearance or any of that other stuff, I'll have to pay closer attention next time I watch a movie. Maybe I'll turn them on and off and see if the screen characteristics change.
Interesting stuff.

Got my ideal lume standard from cinema quest today. Got her hooked up on the back of my TV and adjusted the brightness to just below the reference ambient light pattern on the DVE calibration DVD.
So far it seems pretty nice. If nothing else, it provided a comfortable amount of light in the room with no glare.

Yeah, I am in Oklahoma. Did you order on Friday as well?
I plugged my light into one of the secondary plugs onto my APC unit that is controlled by the master plug (where my receiver is plugged into). Now, the light automatically comes on when I turn on my receiver so that is pretty cool. I had to dim down the light quite a bit with the built in "dimmer" (its just a dark piece of plastic or something that you can rotate around the light bulb to adjust the brightness.) The dimming feature is very basic but works surprisingly well.
I am glad that I made the purchase.

Yup, same as you. Even if it came today, wouldn't been able to hook them as I'm watching the Yankees cruise to their 27th championship! It hurt, but I sold my game two tix. I was at the stadium form ALCS clinching game, so it was good enough for me.
