Product Benefits
Retrofit Existing Streetlights for Smart City Applications
- Onboard auxiliary and DALI bus power supplies help allow for a standard luminaire to be retrofitted and converted to a Zhaga-D4i supported platform, ready for communication nodes and sensors
- A small aesthetic form factor means discreet deployment of DC power supplies, having minimal impact on a neighborhood
- Control devices protected with surge protection on the mains input as well as the DALI bus and auxiliary rail
- With power supplies delivering higher power output (+66%) than the minimum requirements of Zhaga-D4i, you can select from a larger range of connected control devices and sensors
- Pole and wall mount options not only support DALI luminaires to be retrofitted, but control devices can now be deployed where lighting control isn’t needed

Frequently Asked Questions About Zhaga-D4i Retrofits
How can existing DALI streetlights be upgraded for smart city applications?
Many municipalities and lighting operators are looking to add sensors, communication nodes, and connected lighting controls to existing street lighting infrastructure without replacing the entire luminaire. Retrofit solutions that provide both power and connectivity can help accelerate smart city deployments. TE Connectivity's LUMAWISE Endurance Power bridge helps transform standard DALI luminaires into Zhaga-D4i supported platforms with onboard auxiliary and DALI bus power supplies, supporting a wide range of connected control devices and sensors.
What power is required for Zhaga-D4i sensors and connected control devices?
As smart city applications continue to evolve, sensors and communication devices may require more power than the minimum levels defined within the Zhaga-D4i ecosystem. These limits, 2W for a Type A devices and 1W for a Type B, can be a challenge for feature rich control devices. TE Connectivity's LUMAWISE Endurance Power bridge offers a viable solution, delivering up to 6.5W on the auxiliary rail and up to 90mA on the DALI bus, exceeding minimum Zhaga-D4i power requirements and supporting a broader range of sensors and connected control devices.
How can connected control devices be protected in outdoor lighting installations?
Outdoor lighting infrastructure can be exposed to electrical surges, temperature extremes, and harsh environmental conditions. Protecting connected devices is important for maintaining long-term system performance. TE Connectivity's LUMAWISE Endurance Power bridge includes surge protection on the mains input, DALI bus, and auxiliary rail, with IP66 protection and an operating temperature range from -40°C to 70°C, supporting reliable outdoor deployments.
How do I add Zhaga-D4i functionality to an existing DALI streetlight?
Existing DALI streetlights can be enhanced for connected lighting applications using retrofit solutions that provide both auxiliary power and DALI bus power. This can help support Zhaga-D4i sensors, communication nodes, and control devices while avoiding the cost and disruption of replacing the luminaire. TE Connectivity's LUMAWISE Endurance Power bridge is designed to help enable this transition by converting standard DALI luminaires into Zhaga-D4i-ready platforms.
