Has anyone tried this one?<HR></BLOCKQUOTE>
I might have a bag of these... let's see...
Let's see... Hosfelt # 25-342...yup that's the one.
The beam is square in shape, very narrow with a darker spot in the center.
Taking picture... click!

In this picture, the LED was fired at the target from 3 FEET, so you can see its beam is very narrow. That is one reason why its candela rating is so high.
At 30mA drive current, my meter says 23.2 foot-candles in intensity. For this measurement, the LED was fired at the sensor (the diamond-shaped thing in the picture) from 12" away.
Hope this helps.
