With a distortion-free optical-grade glass lens and quiet electronic ballast to eliminate bulb flicker, this magnifying lamp is exceptional value.
Ideal for detailed work, the 5" 3-diopter lens focuses at a comfortable distance (3" to 9") and is encircled by a 22-watt fluorescent bulb that generates a cool, shadow-free light. Its spring balance mechanisms are fully enclosed and the arms extend up to 47". The lamp head is adjustable for viewing angle. It has an integral flip-up lens dust cover, and comes with a 2-1/2" capacity table-mounting clamp.
UL/CUL certified. A surprisingly good-quality lamp.
To let you use the lamp in a dog hole, stainless-steel bushings with a 3/4" or 20mm outside diameter are available separately. Both are 1-1/8" long with an inside diameter of 1/2". Bushings are made in Canada.
