The R-90M "Munchkin" is the smallest 8-point adjustable ring light in existence. The "Munchkin's" simultaneous pinpointing of light is achieved as the 8 light sources are precision mounted in unique "gliding" carriers, providing the uniformity of a single convergency point.

R-90M's significantly smaller size, simultaneous light pinpointing and non-reflective black anodized coating enable users to adjust light output to match their specific applications. Light output is brilliant, cool and perfectly balanced.

The "Munchkin's" patented glide system is activated via a side-mounted, milled edge thumb wheel. This simultaneously adjusts all (8) point light sources from 0-90°. R-90M is effective over the full 360° range with a temperature operating range of -40°F to +600°F.

The precision system's 8-point light sources are the highly polished terminations of the systems's optical glass fibers. The R-90M "Munchkin" also offers darkfield capability.
