Yes, that's what I was thinking of using them for. A ring of white LEDs
around the lens may be useable as a cheap alternative to a ringdlash
(which I don't own, and can't justify buying).

I would have thought the problem with doing that is that the red LED
output is a very narrow band of wavelengths. It may not compensate that
well on colour film
I guess the thing to do is to try it. OK, sometime when I've got some
spare time I will pay around with various LEDs, a camera and a grey card.
