I need an IR source (800 nm) that produces a beam about 1ft by 1in at
a distance of about 1.5m with the intensity equal to the center of
a flashlight bulb beam.  It doesn't matter if other freqencies are
present but it would be nice to avoid them (reduce actual heat from the
source).
I am thinking of flashlight bulbs (a line of them) in a reflector aparatus,
does anyone have any ideas on this?  BTW, the solution needs to be CHEAP.

Thanks.
