240V solar lead acid LED head torch. (With schematic.)

This is by far the chunkiest head torch I've taken apart. While the concept of solar recharging while on your head is interesting, it's so awkward that I think you'd probably want to take it off immediately after use.
It does work. It provides a good wash of light and a slightly too narrow beam for close work. I'm also pretty sure the battery will run the LEDs for a good length of time at a gradually reducing intensity as the battery discharges. The 3 ohm resistor does hint at running the LEDs at around a watt for either the COB or beam.

I'll be keeping the little solar panel, battery, LEDs and reflector. But other than that this light is just a bit too bulky to use versus a compact lithium powered unit.

I'd estimate the power factor as being in the region of 0.016 because it's deriving a 4V supply from 240V via a phase shift. If being charged at apparent power the unit would meter at 14W instead of less than half a watt real power.
