HLQ 235

HLQ 235 transmits UV-A and UV-B while blocking the deep, high energy wavelengths that cause ozone generation and pose the greatest exposure risks.
Special applications for HLQ 235 are anti-bacterial and other lamps where UV transmittance in the germicidal range is required, but where deeper UV radiation or ozone generation is undesirable.
  • HLQ 235 ~ 30 ppm OH*
