Dolan-Jenner's Fiber-Lite® MH-100 Metal Halide illuminator elevates illumination to a new level. It delivers more than two times the light output of a standard 150W Quartz-Halogen Illuminator. It is designed to produce a brilliant white light with true color rendering and balance. Features include 5300K color temperature, 20 to 100% intensity control via manual iris, low housing temperature, and removable UV/IR cut filter. With the UV/IR cut filter removed, the full UV-NIR metal halide lamp spectrum can be utilized. Additionally, built-in external filter holder and available tempered filters (35mm dia. x 2.5mm thick) allow modification of the illuminator's spectral output. Optimize the light output by using fibers with a core diameter of 3/8" to ½".
