Leitz Wetzlar SM LUX POL / LM LUX / Dialux 170 High Power Light


This LED illuminator replaces the original Leitz Wetzlar SM LUX POL / LM LUX / Dialux 170 light source. Provides a whiter, brighter light than the original, while consuming 90% less energy and generating 90% less heat. Intensity control is continuous from 0-100%. Problems with heat damaged bulb sockets, connector and power supply failure are all eliminated. Never change bulbs again. Don’t waste money on a new microscope because of a bad illuminator. Your “old” microscope probably has better optics and mechanics than a new one. You can keep your perfectly good microscope working for a fraction of the price of an inferior new one. Bring your Leitz Wetzlar microscope up to date. Replace the old SM LUX POL / LM LUX / Dialux 170 microscope light with a new Nanodyne LED system. All Nanodyne illuminator systems include the power supply and required cables. Everything required for the illuminator is included. Your new Nanodyne illuminator will add decades of useful life to your microscope.

This illuminator is also compatible to LM LUX and Dialux 170. If your lamp port has same aluminum adapter as shown in the product photos, this illuminator fits to your microscope. Please see product photos.

This light is twice as bright as our standard replacement for the original Leitz Wetzlar SM LUX POL / LM LUX / Dialux 170 light. If you found the original light to be drastically inadequate this is probably the one you want. If you found the original to be acceptably bright, or even somewhat inadequate, our standard unit will meet your needs at lower cost.
