ASL23 LED Street Light: Efficient, Serviceable Lighting for Road Projects

Designed Around Practical Road Lighting Requirements

For contractors, lighting designers, and project buyers, a luminaire's value depends on how well it fits the installation. Energy performance matters, but so do optical selection, mounting flexibility, component access, and control compatibility.

The ASL23 LED street light combines these considerations in a product series intended for project-based specification. Its appeal is not one parameter alone, but the combination of features that can help match the luminaire to a particular road or outdoor site.

ASL23 LED Street Light: Key Features at a Glance

The following features are taken from the ASL23 product brochure. Final project requirements should be checked against the selected model and its supporting documentation.

High Efficacy Matters—But Useful Road Illumination Matters More

The ASL23 brochure lists luminous efficacy of up to 200 lm/W. Luminous efficacy describes how much light a luminaire produces per watt of electrical input, making it an important starting point for energy-performance comparisons.

However, a higher lm/W figure does not automatically mean better illumination on the road. Light falling outside the intended area may add little value to the project. The selected luminaire must also provide suitable distribution, uniformity, and glare performance.

Compare the Exact Proposed Configuration

For a meaningful assessment, request test data that matches:

• The rated power and driver setting.
• The LED package and colour temperature.
• The colour rendering specification.
• The lens and optical assembly.

Optical Options for Different Road Layouts

The ASL23 brochure lists Type I, Type II and Type III distributions. These options allow designers to consider different ways of directing light along and across the target area.

Selecting an optic requires more than knowing the road category. Pole height, spacing, setback, road width, and mounting arrangement all influence the result. A narrow access road and a wider industrial estate road may need different distributions even when their luminaires operate at the same wattage.

Verify the Layout with Matching Photometric Data

Before placing a project order, use an IES or LDT photometric file matching the proposed configuration in a lighting calculation. DIALux or comparable software can help assess whether the layout meets the applicable project criteria, such as those based on EN 13201 or local requirements.

Outdoor Protection with Maintenance in Mind

Road luminaires face dust, rain, vibration, and temperature changes. The ASL23 brochure specifies IP66 ingress protection and IK10 impact protection, together with a die-cast aluminium body and anti-corrosion powder coating.

Neither rating alone establishes suitability for every coastal, chemical, or highly corrosive location. For demanding sites, confirm coating requirements, operating-temperature limits, and relevant corrosion-test documentation.

Tool-Free Driver-Compartment Access

Maintenance access is a practical part of long-term product selection. The ASL23 provides tool-free access to the driver compartment, and the brochure shows an anti-fall retaining rope. These details are useful when planning component access and servicing at height.

Tool-free access does not mean every repair is tool-free. Electrical isolation, safe access equipment, and qualified maintenance procedures remain necessary.

Adjustable Installation and Control Configuration

Mounting Adjustment from −15° to +10°

The ASL23 supports horizontal and vertical mounting arrangements, with adjustment from −15° to +10° in 5° steps. This provides flexibility when aligning the luminaire with the proposed lighting layout.

The final angle should follow the approved calculation. Additional tilt can change glare, spill light, and illumination on the road.

Photocell, NEMA and Zhaga Options

The brochure shows photocell, NEMA socket and Zhaga socket options. These are relevant when specifying automatic switching or connected lighting equipment, but a socket alone does not establish control functionality.

Before ordering, confirm:

• The socket variant and electrical configuration.
• The driver control interface.
• Controller compatibility and power requirements.
• The required switching, dimming, or monitoring functions.

Do not assume that a socket option automatically includes DALI, D4i, wireless connectivity, or a lighting-management platform. These functions require configuration-specific confirmation.

Specify the ASL23 Around Your Project

The ASL23 is worth considering for road lighting projects that need high catalog-rated efficacy, outdoor enclosure protection, and accessible electrical components.

To help select a suitable configuration, share the following information with Alite Lighting:

• Site geometry: Road width, pole height, spacing, and mounting arrangement.
• Lighting criteria: Applicable standards and project performance requirements.
• Light quality: Preferred colour temperature and colour rendering.
• Electrical requirements: Supply voltage and surge-protection requirements.
• Controls: Photocell, dimming, or connected-control requirements.
• Environment: Temperature conditions and coastal or corrosive exposure.

Before approval, request the matching product specification, photometric file, relevant test documentation, and lighting calculation for the proposed configuration.
