o I'm kinda knew at this stuff so I could be way off base, BUT I think that you
o want a wide beam pattern to get the smokey's on either side of the road, as
o well as in front of you.  I believe a projector beam would project the IR way
o off ahead of you, but be ineffective on the guns on the sides of the road close
o to you.  Maybe a combination of a wide beam and a pencil beam to make sure them
o smokey's can't see a thing no matter where they are would be the ticket...

Mike has a valid point.  However, if you use one of those IR filters you 
referred to earlier, the beam pattern of the light source shouldn't have 
much effect.  The source of heat being radiated from the car is the 
filter  itself and will be automatically sent in a very wide pattern as 
black-body radiation.  The "filter" will be heated by the visible light 
of the lamp and then it becomes the heat source radiating heat in all 
directions.

A major point of concern should be the amount of heat build-up in the 
lamp istelf.  I have seen IR lamps which have gotten hot enough to 
actually soften the glass of the lamp enough so that it deformed 
significantly.  This was with an element rated at 250 watts.  I think I'd 
be hesitant to operate the lint blinders unless they were actually 
necessary.  They will need cooling.

BTW Lint?  They ain't important enuf t' be fuzz.  :-)  Especially after 
my strange encounter of the wrong kind with smokey over in MD yesterday.  :-(
