50–320W Adjustable-Mount LED Street Light
The R.327X LED street light uses a separate pole-mounting connection for horizontal or vertical installation, with a 0–15° adjustment range to help align the luminaire with the road layout.
Three die-cast aluminum housing sizes cover 50–320W for motorways, urban roads and pedestrian routes. IP66 protection, separate optical and electrical compartments, and a tool-free top-opening cover support outdoor installation and service access.

Adjustable Mounting & Product Design
Horizontal or Vertical Mounting with 0–15° Adjustment
The independent pole connection allows the luminaire to be mounted horizontally or vertically. Its 0–15° adjustment range helps installers set the light to the intended angle for the road.Choose the mounting orientation together with the pole arrangement and optical distribution. The model comparison above lists dimensions for both installation positions.
Tool-Free Access to a Separate Electrical Compartment
The top-opening electrical compartment can be opened by hand without tools. The light source and electrical components occupy separate compartments, helping keep their heat sources apart.A cover-opening power-off connector is available as an option. Specify it when selecting the service-access and protection configuration for the project.
Smooth Die-Cast Housing for Outdoor Use
The housing and pole connection are made from die-cast aluminum alloy. The smooth exterior is designed to limit dirt buildup and reduce wind resistance around the luminaire.Tempered glass protects the optical surface, and the complete luminaire carries an IP66 protection rating. Exposed fasteners are stainless steel; curved tempered glass is available as an option.
Optional Control Interfaces and Surge Protection
Select constant-on operation or 0–10V dimming to suit the project. NEMA or Zhaga interfaces, photocell accessories and intelligent control accessories are available for compatible configurations.Optional protective accessories include an anti-falling steel cable and surge protectors rated at 10kV, 15kV, 20kV or 40kV. Confirm the driver, interface and control requirements when requesting a quotation.

Where to Use the 50–320W Adjustable-Mount LED Street Light
The R.327X series provides horizontal or vertical mounting with 0–15° adjustment. Choose the mounting position, housing size and optical distribution together for the road geometry.
Urban Streets and Main Roads
For road-lighting layouts that require the luminaire position to be aligned with the carriageway. Review the mounting angle alongside the selected distribution and pole spacing.
Pedestrian and Local Access Roads
Evaluate the smaller housing and available lower-wattage configurations for narrower routes. Check illumination and glare rather than selecting a model by wattage alone.
Rural Road and Existing-Pole Upgrades
For road renewal projects with different pole-arm arrangements. Confirm horizontal or vertical installation, connection dimensions and the intended adjustment angle.
Bridges and Elevated Routes
For proposals where installation orientation and access to the electrical compartment need careful planning. Confirm mounting, wind and vibration requirements for the project.
Application images illustrate typical settings. Final selection depends on the lighting calculation, mounting conditions and confirmed product configuration.
