get a step down transformer whose output is equal to the voltage of your bulb
only the iMac and the mac Pro
240v
both
Answer for USA, Canada and countries running a 60 Hz supply service.If we assume that the resistance of the light is R then the amps drawn by the 100 Volt light is 100 divided by R; and the amps for the 240 volt light is 240 divided by R. Therefore, at 240 volts the light will draw 2.4 time the current it would draw at 100 volts and will likely burn out the bulb immediately. Correction: The answer above assumes the R of both lamps is the same. Most likely they are not.A 100W lamp designed for and supplied with 100V draws 1A with an R of 100ohms.A 100W lamp designed for and supplied with 240V draws 0.42A with an R of 571.43ohms.The Rs do not change. I assume the circuit has not changed so it is a 100V circuit.If you place the 100V across the 571.43ohms you get a current of 0.175A.The lamp designed for 240V, when placed on a 100V circuit, would not glow and would not burn out.Going the other way and placing 240V across the lamp designed for 100v you get a current of 2.4A. Since it is designed for only 1A it would most likely burn out.All this is very technical and to the questioner I apologize. The answer is:NO, YOU CANNOT REPLACE A 100V LIGHT BULB WITH A 240V LIGHT BULB.As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.Before you do any work yourself,on electrical circuits, equipment or appliances,always use a test meter to ensure the circuit is, in fact, de-energized.IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.
i am quite sure these adapters have a "resister"of sorts (voltage regulator) in them which holds back any voltage above say 100v. So they are still runnig internaly at 100v even when plugged into 240v outlet
There will be no problems as the Mac laptops are designed to work internationally with a line voltage ranging from 100V to 240V.
yes.
PL mean Plug in - Light Bulb, the most comment application is CFL (Compact Fluorescent Lamp) which require assistance components to make it work or light up, different to incandescent light bulb, it can light up by just itself direct connect to our home electricity ac 100v to ac 240v.

if i have a breaker that has a 120/240v and my dryer has a 240v plug can i change the receptacle to a 240v
