AFAIK, both incandescent and LED aisle lighting can both be dimmed by reducing the current. How that would be done depends upon the type of power supply used. Of course, you would still need to meet all building code and safety regulations. How do the regulations specify the brightness of aisle lighting and exit signs? Is it an objective measurement (e.g., footlamberts)? Or is it a subjective judgement made by the inspector? Unpowered "glow in the dark" materials are either energized by being exposed to bright light, or contain radioactive materials. Neither is probably practical for widescale use in a theatre. There ARE electroluminescent "cold light strips" that are powered, and give off a softer glow than LEDs or tungsten lamps. ------------------ John P.

Will said: "I come to think of it red or amber lights should be used--old night vision trick...."Yes, since red light does not excite (and fatigue) the rods of the eyes, your dark-accomodated night vision is not lost. Red light would be a good choice to illuminate entrance hallways to an auditorium. Sounds like you've stood night watch a few times, or are a stargazer. On the other hand, the eyes are most sensitive in the green portion of the spectrum, so green LEDs can be really dim and still be seen in the dark. ------------------ John P.

While perusing this thread, I recalled a wonderful house that I patronized in my early teens, the Fox Academy Theater, located at Crenshaw Blvd. and Manchester Blvd. in Inglewood, CA, and I thought some of you might enjoy this reminiscence.The Academy was designed built in the early 50s as a first run movie theater. Apparently Fox spared no expense to ensure that it represented the latest state of the art, and that the customers knew it! To begin with, a poster case in the lobby was devoted to technical information for the amazement of patrons, featuring brands and details of projection and sound equipment including photos, and house mechanical details. While the aisle lighting was the usual code-required style of incandescent fixtures on alternating seat ends, the aisle carpeting had fluorescent dyes in the floral pattern, and recessed UV downlights in the ceiling caused the carpet to glow beautifully when the house lights were dimmed. This made navigating the aisles in the darkened house much easier. The title curtain, when closed, was bathed with slowly moving clouds from an effect projector in the booth. The architecture featured a tall pylon with a spiral ramp from top to bottom that served both as an architectural feature and for sign maintenance. Vertical neon letters broadcast the name ACADEMY on two sides, and special neon letters that were separately switched spelled the word PREVIEW on nights when new releases were previewed. This house still stands, albeit serving as a church. The original curved marquee’s ACADEMY lettering remains, though the marquee letters now spell out service times and other pertinent information. Truly this was a theater where the spirit of showmanship reigned supreme! “Those WERE the days.”
