I never knew this...

This is something I've wanted to experiment with for a long time. You can pick up a lot of IR with a standard digital camera too. (I also had an ex-bank security camera that was extremely sensitive to IR and gave a brilliant picture even in very low light conditions.)

When I enquired at the electronics shop a few months ago the guy behind the counter suggested that the cost would be prohibitive if I wanted to flood a room with infra red light. May have a nosy on the web.

Are you suggesting, sirs, that I am some kind of cwiminal? The nerve! :roll:

I wonder how one of those heatlamps, used for piglets and chickens would work as an source of IR-light?
200 or 300W it would light a bigger area than a diode
but then again they give of visible (red) light also

You could install them behind filters, in fact I think it's been done (going by what the guy at Emery's told me) but it sounds awfully inefficient.

He he ;-)

Well, either I'm mixing up my light sources or Mr. Emery was bulls***ting me. I did think of using an awway of LEDs, though. Something for when I have a little more surplus cash, I think. :-)
