RED LED Darkroom light

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.
 
Hi Duke, my neice also does black and white photography.
She uses E27 GU10s in red 620nm.
They have 20 red LEDs in each. She has 4 of these and the dark room is very red!!. She says it works the same as incandescents but could be brighter if she added more.
