is the duration of the illumination settable?
Previous reply says 4 AA and another reply says 4 months but the replies do say it's for a different make.
Any idea about battery life & type ?
4 AA Batteries in the ones I have. Different make but very similar. Use Duracell and they will last for ages. Mount them as in picture and you get a downward facing light and other way up for a brighter more room filling light.
how many batteries does it need?
