Using your 4W LED candle globe is easy. First, make sure the power is off before installing it. Connect it to a suitable power source within the 220 - 264V AC 50/60Hz range. If you want to use the dimming function, it's best to use a recommended trailing - edge dimmer. When using it with a sensor, just follow the sensor's installation instructions. As for maintenance, keep the globe clean by gently wiping it with a dry cloth. Avoid using abrasive materials that could scratch the diffuser. If you have any issues with the dimmer load, always consult a licensed electrician. And remember, this product comes with a 3 - year replacement warranty, so you can use it with confidence.
