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

How high are your ceilings? We designed the first Christie CounterAct fixture to support higher ceilings 22’/6.7m or higher. The second version we’ll launch later this year adds support for lower ceilings (lower than 22’/6.7m). Have questions? Just ask! Contact us »

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.

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