Professional quality - CE certified (international safety compliance standard). Multi-function - Can be used as a light only, magnifier only, or as a lighted magnifier. Ideal for medical, dental, cosmetology, skin care, small-parts manufacturing and other applications. Superb illumination - Lamp head contains an efficient, 8” diameter, replaceable, 22-watt fluorescent bulb; keeps unwanted heat to a minimum while providing excellent light and clarity. Diffused bulb-cover prevents accidental contact with bulb and spreads the light evenly across your work service. Excellent magnification - High-clarity magnifying lens is approximately 5" diameter (4-3/4” actual), and contains an inset, 7/8” diameter, high-power lens. The primary lens is 5-diopter (2.25x power with a focal length of up to 10”), and the inset lens is 8-diopter (3x power with a focal length of up to 3”). Folding lens cover - Hinged lens cover protects the lens from dust / scratches while not in use, and blocks reflected light when the unit is used as a lamp only. Versatile - 360 degree swiveling head (180°each direction) and the 39" rotating, retracting arm allow for precise positioning. Adjustable tension knobs and position-locks guarantee the placement is maintained. Adjustable working height from 36" - 72”. Steady - Five rugged, weighted-steel legs form the 28” wide base and provide best-of-class stability; swiveling, easy-roll casters / wheels ensure easy mobility. (Minor assembly of base required). Includes: CE-certified magnification lamp with weighted, rolling base. Attached power-cord, 7.5’ long (USA standard 3-prong grounded plug). Assembly wrench and complete hardware package.
