I had a cheapo 29 led flash light with 3 AAA's in a holder. I went to a thrift store & wiped them out of TV remotes. I took out all the IR LED's from the remotes, then changed them out one by one until I had 29 IR LED's installed. Interesting because you don't know if it is off or on, and you have to hide it for people don't play with it & leave it on. I checked it out with my night vision, and it is not that bright, I am definitely going to have to increase the voltage, by adding a couple more batteries in series, so that is the tricky part, getting them nice & bright without over doing it & ruining the whole project.
