Q1: How does the light switch work? (Do the two lights work independently from each other)

A: This lamp has a toggle switch on the base. The two lights work independently from each other.

Q2: What is an LED bulb?

A: LEDs are tiny light bulbs that fit easily into an electrical circuit. But unlike ordinary incandescent bulbs, they don't have a filament that will burn out, and they don't get especially hot. They do dozens of different jobs and are found in all kinds of devices. Among other things, they form the numbers on digital clocks, transmit information from remote controls, light up watches and tell you when your appliances are turned on. Collected together, they can form images on a jumbo television screen or illuminate a traffic light.

Q3: What is the wattage?

A: This lamp uses 20 LED's (Light Emitting Diode) on each shade. Each bulb is 2 watts. With the 20 combined it will eminate 40 watts. Replacement bulbs can be found at a local hardware store.
