Sill Lighting’s range of 003 metal halide projectors have been used in a lighting scheme designed by Arup’s lighting designers for the California Academy of Sciences in San Francisco.
The high power projectors installed above the glass ‘bolla’ housing the rainforest exhibit provide the life support lighting that supplements the daylight that enters through the skylights in the concrete structure of the outer, living roof.
Positioned in the confined space between the concrete roof and the 90-foot diameter glass dome, they illuminate through the glass onto the rainforest canopy, with its spiralling path that leads visitors through the close-up rainforest experience. Arup specified 140 one and two kilowatt 003 series high power projectors from Sill, designed for the Osram HQI-TS lamp, as the light source has a high Photosynthetic Active Radiation (PAR) efficiency, making them the closest to daylight.
