Yep. Trawl through your local Thrift Shoppes and Junque Emporioums.
You'll find an old fluorescent camp lantern for cheap. Pick one
that uses 2 6V Lantern Batteries, or one using 8 or more C or D cells.
They are cheap. Then, wire them externally -- using their 12V adapter
'port' -- or, pop the case and wire in your own power cable. I've
done this to get light for the over-night stint at our local
Amateur Radio Field Day operation(s).
Sure doesn't suck down the battery(s) like those incandescents
