Great googly moogly! That's no torch, it's a space station.
It doesn't make a lot of sense, mind… The output is low, which combined with the battery life makes me assume that the cells just can't power the 7 emitters properly. The draw on a P7 is usually in the 2.8A region so it doesn't look like there's any way these are getting even half that.
I guess they could take the same body and do a 3-emitter unit, basically 3 torches in one instead of this silly thing. It'd probably beat the output for that matter.
