This is an excellent magnifying lamp. Its array has 56 LEDs with a color temperature akin to daylight (6500 kelvin), making it well suited for task lighting.
The 5" 1.75X optical-grade glass lens focuses at a comfortable distance (3" to 9") for detailed work. Its spring balance mechanisms are fully enclosed and the lamp has a maximum overall extension of 47".
The lamp head is adjustable for viewing angle, has an integral flip-up lens dust cover and comes with a 2 1/2" capacity table-mounting clamp. The LEDs are rated to last 50,000 hours, equivalent to 5 hours per day for 27 years. UL/CUL certified.
To let you mount the lamp in a dog hole, stainless-steel bushings with a 3/4" or 20mm outside diameter are available separately.
