Square room size (length x width) = 25 ft. Web the device’s coverage area is dependent on the strobe’s intensity, measured by the listed candela (cd) rating or the luminance flux per solid angle omitted by the strobe. However, many designers leave the selection of strobe lights up to the installation company. The code states that “any design that provides a minimum of 0.4036 lumens/m2 (0.0375 lumens/ft2) of illumination at any point within the covered area as calculated for the maximum distance from.
