SmartNight HID
CMS Capable stand alone dimming ballasts for HID lamps

45/50/60/70/90/100/140/150W The SmartNight ballast is a stand alone HID ballast designed for street and road lighting applications which only have one switched supply available to the lantern, switching to centralised around midnight. The ballast will switch on at full power and dim to 75% or 50% light output at a pre-determind time. Smartnight ballasts are WiMAC compatible so it’s easy to install LeafNut, at any time, and make further carbon reductions and energy savings.

SwitchedDim HPIDD
CMS dimming ballasts for HID lamps

The SwitchedDim range of ballasts are a stand alone HID ballast designed for street, road lighting and indoor applications.

Switched Supply Operation – The ballast switches on at full power and dims to a predetermined level when the switched supply is absent. The ballast will then quickly return to full 100% output when switched supply is present. Reduced Energy Consumption – A standard SwitchedDim ballast saves 30% of power when dimmed. Presence Detection – The lamp will quickly return to 100% when motion is detected.
