Using your Pedro LED Magnifying Glass Desk Lamp is a breeze. Just touch the switch on the lamp body to turn it on or off. You can also adjust the brightness using the 3 - way dimmer according to your needs. If you need to fix the lamp in a certain position, use the included clamp. When it comes to maintenance, keep the lamp clean by wiping it with a dry cloth regularly. Avoid using harsh chemicals as they may damage the lamp's finish. Since it's an LED lamp, there's no need to replace bulbs often, but make sure not to exceed the maximum bulb wattage of 7W. Always ensure the lamp is unplugged before any cleaning or adjustment to avoid electric shock.
