I’m working on making a US Incandescent light bulb compatible with 220v 50hz power so it can be used in China. The tungsten filament looks great and I’d like to keep the bulb (I don’t want to source a new bulb locally). Some google search indicates a solution simply by connecting a silicon diode (e.g. 1N4007) in series with the bulb to permanently dim it. Someone also pointed out that this would cause flicker problems. Anyone have any comments on the feasibility of this? Will the flicker be noticable? More importantly, is this procedure safe? Of course the “artistic” bulb will not be of heavy duty daily use, but are there any foreseeable problems?
