LED safelight bulb
This 7.5W equivalent LED bulb threads into any standard bulb socket and provides just enough light to work in the darkroom: toss it into a table lamp or a ceiling fixture for a quick, inexpensive safelight solution.
Like any safelight bulb, it's best to leave at least 4 feet or distance between bulb and paper. If you're not sure how to lay out your darkroom, try a paper test before going into production. And remember: safelights are for paper, not for film. Film needs complete darkness, and a safelight will fog it.
