Thanks for the replies all.
these are a 4" dia, they do run on 3 AA batteries, and once turned on, and left on, they will last on average 3 months.
If someone has a high res picture, I could get a better sample, just email it to me at 4x4ric@gmail. I can even make it one of the clubs meetings to show a real sample in person, or meet up with someone anytime.
That sample pic was something I had the art dept put together in under a minute lol.
