Did you know that APL Engineered Materials, Sunmaster’s sister company located in Urbana, IL, designs and produces the majority of the world’s chemicals used within ceramic and quartz metal halide lamps? APL’s team of physicists incorporates proprietary processes to manufacture extremely small amounts of chemicals. These chemical compounds are comprised of precise ratios of elements such as Sodium, Scandium, Indium and Thalium. The compounds are formed into small ‘pills’ which are injected within HID lamps to broaden and specifically tailor their spectrum.

Sunmaster leverages APL’s expertise and know-how on an ongoing basis to develop lamps specifically engineered for various stages of plant growth.
