The cabin floor accent lights are installed around the contour of each cabin floor duct and provide ambient illumination.
Floor accent light controls are on/off.
The accent lights are controlled from the GCP and the VIP PCU.
Reading and Table Lights
The reading lights and table lights at each seat position are controlled from the adjacent PCUs, scroll-wheel control panels
(shown in Figure 51), and other quick access switch panels (shown in Figure 52). The reading lights as a group can be
controlled from the GCP and the VIP PCU. The table lights as a group can be controlled from the GCP and the VIP PCU.
All reading lights are interfaced with the ground service bus and can be operated using ground service power.
Two reading lights in each PSU provide direct light for the seats. Each reading light is spherically adjustable. Reading light
function controls are on/off.
A table light in the center of each PSU provides light for dining, reading, and writing. Table light function controls are step
dimmable (0/33/66/100%).
