HPA Series — UV-A Medium-pressure Metal Halide LampsHPA UV-A Medium-pressure Metal Halide Lamp
The HPA series is a medium-pressure metal halide discharge lamp optimized for the UV-A band (315 – 400 nm) and a core light source for copying and photochemical processes. The lamp is made from ozone-free quartz and precisely tuned with specific metal halide additives for high radiant efficiency and arc stability.
