Product_description: ['-B Equipped with next generation, surface mount LEDs, innovative design create the new standard for illuminated magnifiers. Highest lumen output in a lighted magnifier Reduced glare, heat and energy consumption Multi-angle LEDs for shadowless lighting at a full range of focal lengths and heights User controlled LED groups shine desired level of light exactly where required Dimming software via convenient, reliable membrane switch Precision ground, optical grade glass, large lens, standard diopter lens. Low voltage power supplies are auto-switchable, plug in by simply switching the end power cord. Auto shut off at 4 hour intervals to prevent energy waste while users are away. High quality die cast aluminum shades and all steel arm components for ESD safety. EZ SWIVELÂ Die Cast knuckle allows for precision holding power at any angle. "Elite" arms are slim but have the greatest holding power of any arm of this type in the world. Virtually "maintenance zero". Voltage: to 4 V. Certifications: Energy Star compliant (each unit uses W maximum). Delivery information: Comes with 5 years or hours pro-rated LED warranty.', 'The O.C. White 82400-4 Green-Lite LED Magnifier has a 7" x 5 1/4" rectangular 4 diopter lens, a 43" reach and a table edge clamp fitting. Green-Lites employ next generation “surface mount” LEDs that produce more light with less glare, consume less power and last longer. The light output of the 8-watt LED array is comparable to a 150-watt halogen. The blended white light is easy on the eyes and the output level is adjustable – simply and precisely – for maximum operator comfort. Green-Lites products are auto-switchable, too, so they can be used worldwide simply by changing the end power cord.'] (Page 1)
