The Phantom Dual CMh System is a highly versatile system that allows you to run a single 315W lamp or both at the same time for 630W of high-PAR CMh light. The dual reflectors can be used in the standard position or rotated 90 degrees downward to give a low-profile hanging configuration that is ideal for tight spaces. Four angled reflector positions can also be set, if desired. The reflectors feature multifaceted 95% reflective European hammertone aluminum, giving excellent light uniformity and diffusion.
