I did a test (without preflashing the paper) and it showed that 2' is the maximum acceptable time that the paper can be exposed to that safelamp from a distance of 1,5m. I used a CD to see the spectrum of this lamp and there was a tiny amount of blue light emitted. Now, if you have the option to put this lamp far enough, you're not going to have any problems with it. I've successfully used this lamp 5-6m away from the paper and I couldn't see any problems. So, why would anyone want to use that lamp? Because it's color is very close to the spectral sensitivity peak of the human eye and it's very comfortable.
    That's what I'm talking about. Not 'safe' enough for me.

    That's the way I see it too. I got quite used to the dark red safelight.

    Thanks for all the input everyone. OC it is for me. The light will be about 6 ' from the paper so I should be fine.

    BTW, I was told by Osram or Phillips (I forgot) that those red LED festival lights are no longer manufactured. Sad really, I think they could be ideal.
    Ralph, http://www.superbrightleds.com. These guys sell red LED safelights with US and euro fixtures. They're bright enough and I've tested red-only papers as safe with them. I use a single light, mounted 8ft up, bounced off the ceiling (about 12 ft high).

    Ilford paper, on the other hand, is probably about the most lenient paper out there WRT to safelights.
    Stop worrying about grain, resolution, sharpness, and everything else that doesn't have a damn thing to do with substance.

    Don't forget the safelight test!

    I don't see anything labeled as a safelight there. Do you mean any of the LED lights available in red color?

    Yeah. Or more importantly, any of the red LEDs that have a narrow bandwidth and cut off above, say, 600 nm.

    This is what I use:

    http://www.superbrightleds.com/cgi-b...%2FE27-W24.htm

    Spectral graphs are at the bottom of the page.

    Have had zero issues and I've tested it (wide version) on papers that really want red (Foma, Emaks, etc.) without a problem - whereas I've tested others that did present a problem.

    Excellent. I picked up a couple cheap little desk lamps with a clamp on it. Gunna use those LED bulbs instead of expensive safelights.
