Optolite Sirius

LED Hi-mast Light

The Optolite Sirius is designed for applications where a high mounting height of 30-40 metres is required such as tower cranes, ports, parking lots and sports stadiums.
Beam angles of 25°, 60° and 90° are available to suit individual applications.
Powers from 150W to 500W are possible.
The fitting uses copper heat-pipe technology to rapidly transfer the heat generated by the LEDs to the massive finned cooling plates.
The Sirius gives cool operation and very high reliability needed in situations where access for maintenance is difficult.
