I thought you only wanted them for a HC so just install, use, remove, no?
I can't find a link to the ones I have. They existed when I was still in Oz and I bought another set in the UK many years ago. I think they still have the original button cells in them!
Yeah, they'll be on for the event and then you remove, turn off and stick someone on a shelf where they can't be turned on. What am I missing? If you're that worried, take the batteries out when not in use.
