The only visible part is a flush mounted LED light assembly, with a visible diameter of just 40mm. The battery and control gear are housed in a remote pod with plug in connector for the mains supply. A spring clip fixing arrangement provides quick and simple installation of the LED luminaire body. For simplicity, the green status LED is incorporated into the luminaire body, enabling maintenance personnel to carry out mandatory checks without requiring access to the remote module. For applications with limited access, an adaptor plate is available which allows the remote gear pod to pass through the luminaire fixing hole. The high power, high efficiency LED light source provides uniform illumination ideal for coverage of open areas.
