The range in output was similar to the range in output seen in standard 40 W to 90 W halogen PAR38 lamps. Energy efficiency regulations have effectively stopped the production of halogen PAR38 lamps drawing between 100 and 250 W, so the performance range is largely the same for currently available halogen and LED PAR38 lamps. Lumen output is slightly less than the 25 W selfballasted CMH benchmark. Higher output metal halide lamps—70 to 150 W or more—are also available, although they require dedicated ballasts and igniters. They are generally used in different applications, such as exterior floodlighting or high ceiling applications.
