The Esquire LED Desk Lamp is an updated version of the classic bankers lamp. It is a nine watt full-spectrum modern LED desk lamp made from satin steel that adjusts with locking keys at the shade and the bottom of the two curved rods supporting the shade. The benefits of full-spectrum lighting are cleaner, glare-free light, brighter lumen output and no hazardous material, i.e., mercury. The wide, shallow metal shade has an acrylic shield that protects the three LED chips. Esquire LED Desk Lamps feature a full-range rotary dimmer switch on the base. CRI: 90; Color Temp: 4000K; 550 Lumens.
