• SL04 is engineered for street and roadway lighting, including:

  • Urban streets and municipal roads

  • Highways and express roads

  • Parking lots and commercial areas

  • Residential and community roads

  • Campus and industrial park lighting
    It delivers uniform, energy-efficient illumination with professional road optics.

• Optics (Type I/II/III/IV/V) are chosen based on:

  • Road width

  • Pole height

  • Traffic flow direction
    → Narrower beams for long, straight highways; wider distributions for residential streets and intersections.

• Spacing should target even illuminance and meet local roadway standards, typically determined via roadway design calculations and photometric simulation so that light overlap and uniformity are achieved with minimal dark spots.

SL04 supports multiple control interfaces to suit smart city or energy-saving strategies:

• 0-10 V dimming

• DALI

• Photocell (on/off based on daylight)

• Motion sensors

• Zigbee (wireless control)
  This enables adaptive and networked control for glare reduction and energy optimization.

Yes – SL04 can retrofit existing HID or traditional street lights if:

• The existing pole/arm mount diameter is compatible

• The luminaire can be mounted or adapted with an arm/bracket to match the old fixtures

• Power and control interfaces (e.g., mains voltage and control wiring) are compatible or adapted
  Retrofitting usually involves confirming mounting fit, power supply compatibility, and aiming adjustments to match roadway light patterns.

To quote SL04 correctly, the following project data is essential:

• Road type and environment (urban/highway/residential)

• Roadway dimensions (width & length)

• Pole locations, heights & arm types

• Target illuminance standards or lux levels

• Control requirements (DALI/photocell/motion/Zigbee)

• Voltage or region constraints
  With those, ZC Lighting can produce a layout, optics selection, and pricing tailored to your project.
