Ny niece is thinking of taking up balck and white photography. Low power incandescent bulbs seem to be thin on the ground so I was wondering if a light based on red leds would do the same thing as a filtered incandescent light in a darkroom.
Would they affect enlarging paper?
How many leds at 20mA would be needed to match a 40W filtered light.
