This 100mm x 75mm rectangular stand magnifier has a 3x 8D lens and a bright white light. Stand magnifiers are also called fixed focus magnifiers, because they have a structure that allows you to lay them flat on the reading material. You do not lift them from the reading material but look down into them. In this position, they have maximum focus. Stand magnifiers have flashlight-stye handles which hold the batteries. This magnifier uses three Double A batteries. The LED light, switches, and battery compartment parts have a lifetime warranty. This is a good magnifier for someone who just needs a little extra light and magnification, as they read mail, newspapers, or look at photo albums. For a small additional price, Contrast Yellow is available as well as an even brighter, Halo LED in White, Yellow, Plum, and Blue.
