Lens colour is a design decision on this platform, not a finish. The S4-711-V-VAD-HPW, marked O2H/V/WVAD/HP, uses a white multi-die LED and on High is certified C-6-16 covering 1206.3 cubic metres, where the red part at identical current manages C-3-14 and 461.8 cubic metres.
Worth reading twice: the white lens doubles permitted mounting height from 3 m to 6 m and, all for the same 16 mA. Over a tall open volume that usually cuts the device count, with no change to loop load per unit.

Specifications from 4188-1073 issue 3.
Compatibility
Same mounting requirement as any S-Quad visual alarm: an IP21 plate under the base, available as the combined S4-701 or as S4-705 plates over existing S4-700 bases. The C-6-16 figure above is only reachable on the High setting, which an Enhanced Loop Card at the Vigilon Plus panel makes available; a Nano loop cannot offer it. If the specification calls for red, the equivalent is S4-711-V-VAD-HPR.
Installation
Mount and wire as the rest of the range, but confirm mounting height first. Anything sited above 3 m depends on the High setting for its certified coverage, making the intensity written into the panel part of the compliance case.
