High-Efficiency Magnifying Lamp - Giant 7" x 6" Lens - Powerful 5-Diopter
<BR><BR>As we age, our eyes naturally lose some of their ability to focus close-in. A teenager can focus on objects as close as 3" but by age 50 that distance can increase to 18" - VERY frustrating when it limits your work or hobby. This premium-grade lamp is a simple and effective solution for seeing almost anything bigger, better and brighter. 36" triple-joint arm has unique internal cantilever system (not external springs like lesser lamps) that lets you adjust without loosening/tightening knobs - perfectly balanced to hold position (can be locked in position if necessary). Heavy-duty die-cast aluminum clamp with no-mark pad, nickel-plated steel screw fits surfaces to 2-1/2"-thick; easy to move remove and takes up just 2" of desk space. Extra-large 7.5" x 6.2" glass lens with 5-diopter (2.25X) magnification lets you see fine detail clearly but still has a practical focal range (distance of text or object from lens) of up to 7". Two 9-watt fluorescent daylight-spectrum bulbs illuminate work area without the heat build-up of incandescent or halogen. Bulbs have 5000-hr rated life inexpensive easy to replace. Conveniently-placed power switch on top of lamp head so it's easy to reach flip-up dust cover protects lens. Overall length 48", weight 11 lbs; 72" 18AWG UL-listed power cord.<BR>
