The high ceilings in the room require multiple fixtures to be installed at each fixture position in order to achieve the target UV power.

We created this Christie CounterAct Calculator solely for the convenience of interested persons to generate a rough assessment of the number of fixtures that may be required in a given space in accordance with current Threshold Limit Values (TLVs) for far-UVC 222nm light as established by American Conference of Governmental Industrial Hygienists (ACGIH) and International Electrotechnical Commission (IEC) standard IEC 62471 Ed. 1.0 b:2006 – Photobiological Safety Of Lamps And Lamp Systems. It is fully the installer and/or end-customer's responsibility to calculate and verify the performance of these fixtures operating as a complete system once installed to ensure proper installation and operational specifications. Product images as shown are for illustration purposes only. Actual product may vary due to product enhancement.

Christie strongly recommends that CounterAct devices be installed by professionals properly trained to work with UVC fixtures.
