Using your Meira Table Lamp is easy. First, make sure to fully charge the lamp for about 3.5 hours using the built - in USB port before the first use. Once charged, it can last up to 7 hours at maximum brightness. To adjust the light, simply touch the touch - sensor dimmer. It's super convenient! When it comes to maintenance, always remember to unplug the lamp before cleaning. You can use a soft, dry cloth to gently wipe the lamp and the shade. Avoid using any chemicals or household cleaners because they can damage the finish of the lamp. Assembly is required, so take your time to put it together according to the instructions. Also, be aware that the lamp contains DEHP and lead, which have health risks related to cancer, development, and reproduction, so handle it with care.
