enLight® HID Retrofit Kit

The new enLight® HID Retrofit Kit is a combination of the enLight® entelli-Ballast™ and the enLight® DOLFin® Pro for installation into relatively new lanterns to make them up to twice as power efficient and make HID lamps (SON or Metal Halide) last 2-3 times longer. Instead of throwing perfectly good lighting fixtures into a skip, the HID Retrofit Kit gives lanterns a new, much more efficient extended lease of life.

The HID Retrofit Kit is easily retrofitted into most lanterns and will typically take just 20 minutes to complete, Simply remove the existing control gear and fasten the entelli-Ballast™ in place using the clips provided. The DOLFin®Pro can be mounted on the top of the lantern via a 20mm hole and comes pre-wired with an RS485 cable that fastens to the socket on the entelli-Ballast™ (it is keyed to ensure it cannot be connected incorrectly) and that provides the power and connectivity for the DOLFin®Pro itself.

HID Retrofit Kit features:

  • Achieve >50% improvement in energy consumption from existing lanterns
  • Significantly reduces maintenance costs due to 2-3 times increase in lamp life

Seamless integration with the enLight lighting platform

All enSense sensors are designed to enhance the capability of the enLight platform. Many of the sensors can be pre-mounted in any of the enLight lantern family but they can also be connected and mounted below the lantern itself (such as the air quality or microclimate sensors) or in the lamp post to monitor water table level in the base of the column or tamper detection of the access panel. Larger sensors, such as the traffic sensor, can be mounted on the post below the lantern but can derive their power and connectivity from the lantern via a simple cable connection. Away from the lamp post, wireless enSense devices (coming late 2017) can connect to the network via the enLight DOLFin® Pro for their data feed to be sent on to the enLight enGauge API.

Cost effective smart city deployment

By deploying the enLight platform on lamp posts across the city, town or campus, a whole host of smart applications can be realised by utilising the network created by the augmented lighting. Multiple wireless technologies do not need to be funded and the inherent value of the street light estate increases as it allows resource reduction or increased efficiency projects to be deployed, without the major capital cost of their own networks. The enSense sensors are fully compatible with the enLight enCore™ Management System or via other management platforms through the enLight enGauge™ API.
