  • Do lenses designed to be made of PMMA work if made of polycarbonate and vice versa?

    Difference in the refractive indexes of PMMA and polycarbonate may cause the light pattern to change. The optical performance of lenses made of alternative materials should be simulated and evaluated case by case. For more information please contact 

    tech support


  • How can I measure the temperature of the lens / reflector in my lamp?

  • Why does a lens, reflector or base part deform or melt?

    Thermal management may not be sufficient or the parts aren’t clean enough and there is absorption in the high radiant flux area. Please follow the material’s maximum recommended service temperature.

  • Who do I contact if I have an inquiry regarding quality?

    Please contact our 

    quality department
