Hi,
Here's an interesting request for information!
My buddy is....ok, don't laugh....a ghost hunter. Yup, for real! He has a lot of fun with it with friends, and they do catch some interesting "data" at times.
He's asking me to come up with a better IR illuminator for use with his digital NV cam. He has seen a cheap one with a few bulbs on it....he'd like me to figure out how to make two of these with 12 bulbs instead of the 8. We can't lay hands on the thing (he just has a pic...yeah, I know....).
I've used IR LEDs in the past but never bulbs....we'd like to power this off 1 or 2 9V batteries per unit. Does anyone have ANY info on where I can find individual bulbs that would be appropriate for this use? The bulbs are about the size of old=fashioned christmas tree lights, not big heat lamps or anything.
Guy's talking about throwing light out 100' with a DIY thing...I've tried to tell him about inverse squares and the like, but he's pretty adamant, LOL....thanks for any suggestions!
