If you start to change the current to an LED bulb the non-dimmable driver will try to compensate and keep the current steady. This will eventually overwork the LED driver and it will fail. Dimmable drivers, on the other hand, are made to handle drops in current. birds eye maple cutting boards

WebScience. Traditional incandescent lights don't care. In fact you will get very similar brightness if you give them 120 volts AC, and 120 DC. LEDs are a completely different story. A single LED typically wants somewhere around 2 volts DC across it (how much voltage it wants depends on its colour), and the amount of current it wants through it ... WebJul 7, 2024 · The "16V" AC transformer will give that voltage when passing its rated current (bell current). If your lamp draws less current then the voltage will almost certainly be somewhat higher, say 18V (rms). Given that an indicator LED drops ~ 1.8V - 3V (depending on its colour), that leaves at least about 15V rms to be dropped across a current ...
