It's not clear from the photo if it uses a reflector. A low powered LED light like this typically use a cheap optic molded into the clear lens. If the focused beam is too weak and doesn't have enough spill light for decent ambient lighting (and remember, I'm comparing this to the light output from a candle, not a lantern), then there's a decent chance that the lens can be unscrewed and the bare LED exposed for more omnidirectional lighting. More harsh on the eyes, though.

I'm a fan of Pak-Lites but they don't let me use up those odd-man-out single D cells I often find myself left with. But to use up those 9V cells that we pull from the smoke detector when they start chirping? Now you're talking.
