Neat Chinese LED lamps part 2.

I took the circuit board out of the smallest unit to see how it compares to the others, and also drew out the schematic.
I changed the capacitor in one of the lamps to make it dimmer too. A bit too dim actually, but the only cap I had handy was a 220nF one.
With the cover off the largest lamp rises in temperature on the aluminium core PCB to around 60 degrees centigrade above ambient after a period of use.
