Next month I will start setting up my darkroom. Seriously this time!
Instead of using traditional red or yellow-green safelights I was thinking of using small arrays of LED lights. They last much longer and they're much more resistant, especially if you move them frequently while a tungsten lamp might broke and they cost quite a lot...
Just stick a 6-8 LEDs inside a diffuser (e.g. a plastic semitrasparent cartridge for 35mm film) and use a dimmer to change intensity of light. One could also put a swtich to select between red and yellow-green.
I guess it won't be difficult to build this as the design requires very basic knowdlege. The only problem could be LEDs wavelenghts... Which wavelenght should I use to prevent paper fogging?
I know that I could use regular household low wattage light bulbs inside red filtered lamps... But if it is easy to get the right LEDs I would prefer to try those anyway...
cheers
