VAD coverage (with multiplication factors applied)

VAD coverage depends on factors such as ambient light and viewing angle (direct or indirect). The table below summarises how the coverage of the BF457A/CX/W increases or decreases based on these factors. To use the table, calculate the lux level of the area requiring coverage, determine whether the viewing angle will be direct or indirect then read off the coverage in the relevant column. For further information refer to our VAD System Design Guide, downloadable from the Documentation tab below.

Lux level in area requiring coverage Ceiling Mounted Direct Viewing Ceiling Mounted Indirect Viewing
000-101 lux 8.3m H x 22.4m W 3.9m H x 10.4m W
101-200 lux 7.2m H x 19.2m H 3.6m H x 9.6m W
201-300 lux 5.7m H x 15.2m W 3.0m H x 8.0m W
301-400 lux 4.2m H x 11.2m W 2.4m H x 6.4m W
401-500 lux 3.3m H x 8.8m W 1.8m H x 4.8m W
501-600 lux 2.7m H x 7.2m W 1.5m H x 4.0m W
