• Two-and-a-half times greater light output than other magnifiers

These magnifiers feature a 22-watt T5-C fluorescent light source that generates 3500 lux at focal distance (2.5 times more light output than standard round-lensed magnifiers). Such powerful illumination is supported by a high-frequency electronic ballast which minimizes heat emission and provides flicker-free operation. With die-cast aluminum housing, KFM-HO magnifiers are ideally suited for heavy-duty application, especially those that require the optimal combination of illumination and magnification. Models feature a 5" diameter optical glass lens, either 3-diopter (1.75X) or 5-diopter (2.25X). Secondary add-on lenses in 4, 8, or 10-diopter magnifications are also available. The 4 and 8-diopter lenses slide into position underneath the cover via a sturdy lens holder, while the 10-diopter accessory lens is attached to the top of the magnifier via a swing-away lens mount. The triple-jointed counter-balanced, concealed spring-arm allows for infinite positioning and may be ordered in 30" or 45" lengths, with clamp-on or weighted base. An adjustable neck supports the head which can move vertically and horizontally to provide total flexibility. Once adjusted, there are no knobs to tighten. Perfect balance is maintained by tempered steel springs. KFM-HO lenses are mounted in an aluminum housing that is non-corrosive and durable. The inside is finished in white to optimize and evenly distribute light. Color: Light Gray.
