O.C. White 42400 Green-Lite LED Magnifier has a round 6 Inch 4 diopter lens, a 43 Inch 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 8W LED array is comparable to a 150W 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. - Equipped with next generation, surface mount LED's, these innovative designs create the new standard for illuminated magnifiers. The specialized design of our Green-Lite Ultraviolet/Visible LED inspection lamp combines two fixtures into one! This fixture can be used in Combination mode, Ultraviolet only, and White light only.
