Every piece of this Professional Worklight was designed with quality in mind. Aluminum radial fins surround the base of the bulb to dissipate heat away from the socket area and switch... extending the life of the bulb, socket, switch, and making it cool enough to touch and rotate! The light housing can rotate up to 540 degrees so you don't strain the "stay put" 24" flexible arm. (Some lights I've tested don't even rotate and bind up the arm!) The light mounts to any surface with the wood or metal screws included (on the side, top, even upside down!), or use the C-clamp for simple bench top applications, all with a precision quick-release. The optional Weighted Base model has two quick release mounting studs and includes all mounting hardware listed above. The large, removable 2X magnifier has a spot 4X magnifier to enlarge all the details. Use with a 100 Watt bulb and improve your work area today with great lighting and magnification!
