This cleverly designed lamp has a weighted base with wheels, making it easily mobile for use at a table or while sitting in a chair. The lamp uses a daylight bulb for clarity, color matching and eye comfort. Plus, it has a second flexible arm with a high quality acrylic magnifier, 5" in diameter, and magnifying 1.75X (3 diopter). Both the lamp and magnifier arms are flexible and can be moved into any position. The lamp includes an 18-watt low heat Daylight tube bulb (100-watt tungsten equivalent).
