ok any ideas.....
i have over head track lighing with a switch & dimmer for green & red and white
i have kodak so-173, 649f , so-120
i dont want to fog them...but i know its not as critical as lets say 25-asa film (talking about ambenint light) my green light is very narrow ..my red has some orange in it
Laser diode pens are very cheap and come in red and green and are very narrow banded. Hook a couple up to the wall box type transformers and you have a very narrow safe light.
