The Ushio SMR-850/D2 EmArc® lighting technology is the culmination of a dedicated effort to bring together the inherent advantages of a number of gas discharge sources into a single light source. The technology equates to a critical blending of rare gas and metal additives to derive, in a single source, many of the key properties and benefits of stand alone Xenon, Metal Halide and Mercury lamps.

EmArc® light sources are a series of highly efficient, Enhanced Metal Arc, DC gas discharge lamps designed for use in medical, scientific, industrial and entertainment settings. EmArc® lamps are a progressive step ahead in lighting technology possessing features that offer advantages to an array of uses for imaging, fiber optic and other important optical applications.

EmArc® lamps have geometric designs which enable alignment in dichroic visible light or UV specific coated reflectors facilitating use in numerous applications like lighting for minimally invasive surgery, curing of light sensitive resins and adhesives and, dental whitening procedures. EmArc® versatility enables its use in a number of entertainment applications including searchlights, followspots, special effects and automated fixtures.
