This is the only table lamp with a light beam that widens or narrows to provide daylight-simulating illumination for hobbies or ambient lighting. Its light beam adjusts to 711 different diameters between 3 1/2" and 19". At maximum zoom, the 3 1/2"-diameter beam produces more than 10,000 LUX (2 1/2X brighter than a typical lamp) that’s ideal for illuminating fine details of crafts, and the 19" beam provides optimal light for reading or ambient illumination. Light is produced by one 50,000-rated LED that generates clarity-enhancing, crisp white illumination that simulates natural daylight to help reduce eyestrain. An adjustable 12" gooseneck can be raised, lowered, or twisted for optimal light projection. Nickel finish. Plugs into AC. 23" H x 6 1/2" Diam. (2 3/4 lbs.)
