WebJul 30, 2015 · LEDs have a characteristic delay when turning them on which may be more than you're used to from a lifetime of incandescent bulbs. Swap the LEDs from one position to another, and the problem should move with the bulb. Replace the LED with the equivalent incandescent (temporarily) and it should go away entirely. WebNov 26, 2024 · For this much voltage, if this was the voltage across that device, then the power across that, power dissipated would be 50 watts. But clearly, in this example, the voltage across the bulb is not 10 volts, we can see it's 5 volts. So the power dissipated in this bulb won't be 50 watt, in fact we can guess it's gonna be lower than that.
