Site-measured / Simulated Lux Readings:
(1) 0.4 lux / 0.33 lux
(2) 0.4 lux / 0.33 lux
(3) 0.4 lux* / 0.42 lux
(4) 1.4 lux / 1.43 lux
(5) 1.3 lux / 1.23 lux
*This reading was recorded as 1.4 lux, which is inconsistent with both the drone photography lighting and the measured lux pattern of Unit #805. Therefore, the reading of 1.4 lux is assumed errant and substituted with the value of 0.4 lux.

Illuminance Impact at Peak Brightness (%)
Notes
1. Peak signage brightness of 300 cd/m², and visual comfort requirements per WeHo's Sunset Blvd Off-Site Signage Policy
2. The size, density, and layout of the signage's linear LED elements have been extrapolated from Gensler's architectural drawings and renderings available in this report from June 2021.
For this lighting study, the LED elements have been modeled at 1.0" wide and spaced at 2.375" center-to-center within the areas of highest density.
3. The Pendry West Hollywood Hotel at 8430 Sunset Blvd. was used as an active precedent for the look and feel of city-approved animated video content.
