Has any ever use a RED LED for safe lighing in darkroom (sic)

Just because a red LED is red it does not mean that it is the correct spectrum.

Make some tests.

RH Designs uses red led's in their lanyard safelights.

LEDs (any monochromatic variety) are very pure, emitting energy over a very narrow band of wavelengths.

Red ones should be safe for use with graded (only sensitive to blue) or variable-contrast (sensitive to blue and green) papers.

Of course no safelight is safe with panchromatic film, although red might be OK with ortho emulsions.

I tried out some cheap LED holiday lights as a safelight, and they did not work well. I think the problem was that what I had were white lights with "red" plastic covers over each bulb. In any event, the conventional wisdom is good: run a test.

I bought 10 red 1 watt LEDS some time ago for $30, they work great, but I forgot where I bought them. They do have a tight 'red' spectrum that works great with MG paper and X-Ray film. I put 2 at the 8' ceiling and I have no problem in trays 4 to 5' away.

I got them from one of the biggest online LED suppliers, I now have a lifetime supply.

Randy Moe, do they screw into "normal" bulb receptacles? Would you mind posting a photo of one? I have a thought to build my own but not if I can buy something at a reasonable price. Thanks.

This is it. Get a candelabra adapter at Home Depot.

Nothing to build, use it bare bulb, aim it at white wall or ceiling and use the bounce.

Study up on light wavelength and power, this bulb is 630 nm, 1.2 watt.

I never turn them off, they use such little power.

I used a short string of red led Christmas lights in my dark room (not red covered clear leds) and they worked just fine. Add Bing Crosby singing Christmas carols and it gives the place a downright festive atmosphere!

I strung up a 100' length of LED XMAS lights in my DR one season, controlled by the "stage" lights foot-switch (off when safelight was on). Not quite as festive as I imagined, so they were demoted to XMAS tree lights (Bing trumped them).
