Not news, particularly not with the corn-cob lamp.

These have been out for some time 2013/4 with corn cob it is quite plain what is going one and good idea to high light again. As for GU10 he says it's a bridge rectifier but does not show part number or anything else to support that. The switch mode droppers would look similar. 16 x 3 = 48 volt he does not say how many watt if a standard 380 mW LED times 16 so around 6 Watt. So that's 23 watt that 1/4 resistor needs to sink. I don't think so.
Clearly that chip is much more than a simple bridge rectifier. There may be danger but since he has clearly made a mistake with the circuitry who knows?
That resistor I read as Orange Blue Yellow so 360k ohms so may watts = 0.147 or 147 mW there is no way this resistor is dropping the voltage to the lamp?
