I originally purchased 12v red led cluster approx 20 leds 10ma, and a 12v white led cluster, approx 30 leds 100ma, for messing about with.
On a visit to local store, they were selling off unwanted portable speaker with battery amp waterproof cd playing boxes. £1...
I combined the two.
Cut out the LS apertures, fitted a couple of switches, the result is below.
Red led's only, 10ma @ 12v, approx 100 hours life.
White led's only, 100 ma @ 12v, approx 10 hours life.
Both on, red led's dim, with my cheapo AA's
Obviously twice the duration with proper alkalines / nimh's.
Batteries, 8 x AA's in battery box, though the switches.
Total cost= £ not a lot, < £10
