Design help for battery powered LED lighting for display case?
The all glass case (except for base and canopy) now has an AC powered four MR16 halogen system. I want to replace that because of the heat, and because I don't want a power cord running from canopy down the glass sides. Ugly.
I'd like to replace those bi-pin halogens with LED lights and power it all with a rechargeable battery.
The canopy over the six foot tall case is 4" deep by 15" wide by 70" long, open at the top. I'd like to conceal the works in that 4" space. I'd want the battery(s) to be easily removeable and reinstallable for external charging. Long life to maximize intervals between charging would be a big plus.
The lights would typically only be used when we have visitors. Maybe for as long as a couple of hours several times a month, but probably typically for much shorter periods.
Ideas? Thank you. --David
