Zircon is a new concept in LED filter design that has been designed from the ground-up for exceptional performance with LED Lights.
Extensive testing shows that across many of the commonly available LED lamps on the market today, Zircon still delivers in excess of 85% efficiency up to 20 months after installation.*
* Test data based on 11hrs continuous illumination per day over 20 months at 1-2cm clearance between LED chip and Lens/Filter interface.
