Application
Metal halide ultraviolet sleeve tube for plant grow lamp.
Product Feature
A doped transparent quartz tube, which has a softening point about 50℃lower than conventional transparent quartz tube, absorbs UV-A / B / C, filters out almost all ultraviolet rays, and has a very low level of OH control ( can be less than 2 ppm). And Extend lamp life.
Product Type
PQ 321 ,standard UV block quartz tube
