The LM-30 DESKBRIGHT 300 Magnifier from Carson features a 4.3" main lens with 2x magnification, as well as a smaller 5x magnification spot lens for very fine print and details. A flexible goose neck allows you to position the magnifier where you need it, and four LED lights with a diffusive cover illuminate your subject. These light diffusers eliminate LED hot spots and evenly distribute the light, and the magnifier's aspheric lens provides a large viewing area while greatly reducing edge to edge distortion. The LM-30 is ideally suited as a reading aid for books, magazines, and newspapers, and this versatile hands-free magnifier works well for crafts, model building, soldering, jewelry design, needlepoint, sewing, quilting, coin and stamp collecting, and more. The light runs on AC power via a USB Type-C cable and wall adapter, but can also run on three AA batteries.
