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.
