Nettet20. jan. 2024 · #5. Capacitor and led driver. In the LED driver controller, a plastic (plastic) capacitor is used to store electrical energy for the use of the bulb. If the bulb is used frequently, these capacitors can last up to a year. However, due to factors such as bulb temperature and ambient temperature, they may have a shorter lifespan than theoretically. NettetTo work out how much LED tape you can run off an LED power supply, simply divide the wattage of your LED strip driver (for example, 100w) by the wattage per metre of your LED tape (e.g. 4.8w p/m). This gives you the total length of LED tape, in metres, that your LED power supply can drive. So in this example…. 100w divided by 4.8w = 20.83m.
