120 Watt LED Street Light | 19200 Lumens | 5000K | 100V-277V | Type 3 | Photocell Optional

Product Overview

This 120 Watt LED Cobra Head Street Light is designed for pole-mounted exterior lighting on public and private roadways. It delivers 19,200 lumens at 5000K, with selectable color temperatures available. The fixture is engineered for Type 3 roadway distribution and supports mounting heights typical of municipal, campus, and subdivision street lighting. The housing is constructed from aluminum alloy with a tempered glass lens, suitable for long-term outdoor use in demanding environments.

Commonly used as a direct replacement for 400W metal halide cobra head fixtures, this unit operates on 100V-277V and is compatible with standard pole arms. The fixture is IP66 and IK09 rated, with ETL certification, and offers an optional photocell for dusk-to-dawn operation.

Core Performance and Output

This fixture outputs 19,200 lumens at 120 watts, providing 160 lumens per watt efficiency. The standard Type 3 optic delivers a lateral distribution pattern suited for roadways and street corridors, with optional Type 2, 4, and 5 optics available for alternate site layouts. The fixture supports 1-10V dimming for adaptive control.

Performance is optimized for mounting heights between 18 and 30 feet. Excessive output may occur at lower mounting heights, resulting in increased glare or over-lighting in pedestrian areas. Uniformity may decrease if pole spacing exceeds typical roadway standards.

Adjustability and Control Options

The fixture supports 1-10V dimming for integration with external lighting controls or adaptive systems. An optional photocell can be installed for automatic dusk-to-dawn operation. The fixture is compatible with standard pole arms and can be oriented for optimal roadway coverage.

Optical distribution can be specified at order, with Type 3 as standard and Types 2, 4, and 5 available for alternate site requirements. No field-adjustable beam pattern is provided.

Longevity and Reliability

The LED system is rated for 131,000 hours (L70), supporting long maintenance intervals in municipal and private roadway environments. The fixture includes surge protection rated at 5kV line-line and 10kV line-earth, suitable for areas with frequent electrical disturbances.

IP66 ingress protection and IK09 impact resistance support reliable operation in exposed outdoor locations, including areas subject to wind-driven rain and incidental impact.

Build Quality and Physical Characteristics

The fixture housing is constructed from aluminum alloy with a black finish. The lens is tempered glass with a polycarbonate overlay for additional impact resistance. The unit measures 24 x 11 x 6.1 inches and weighs 14.5 lbs, supporting standard pole arm mounting.

EPA rating is 2, suitable for most municipal and campus pole installations. The fixture is designed for 50/60 Hz operation and is compatible with 100V-277V electrical systems.

Where This Product Fits Best

This cobra head LED street light is intended for exterior pole-mounted lighting in public and private roadway environments. It is suitable for municipal streets, neighborhood roads, campus roadways, and parking lot perimeters where Type 3 distribution is required.

• street lighting
• roadway lighting
• municipal lighting
• neighborhood lighting
• campus roadway lighting
• private road lighting
• subdivision lighting
• parking lot perimeter lighting

Environmental suitability includes wet locations, areas with moderate wind exposure, and sites requiring impact resistance. Not intended for marine or hazardous environments.

Installation and Long-Term Use

The fixture mounts to standard pole arms using the integrated slipfitter. Installation requires access to 100V-277V power and may include wiring for dimming or photocell control. The 14.5 lb weight is compatible with most existing pole structures rated for similar EPA and load.

Routine maintenance is limited to periodic cleaning of the lens and inspection of electrical connections. The long LED lifespan and robust housing reduce the need for frequent service. Surge protection supports reliable operation in areas with unstable power.

How This Fixture Is Commonly Used

Typical mounting heights range from 18 to 30 feet, with pole spacing determined by roadway width and required light levels. Fixtures are often installed on municipal streets, campus roads, and subdivision entries, with layouts following standard roadway lighting design practices.

Spacing and fixture count depend on pole height, desired uniformity, and site geometry. Higher output can reduce the number of fixtures needed but may increase glare if not properly spaced or shielded.

Safety, Certifications, and Warranty

This fixture is ETL certified and rebate eligible. It is rated IP66 for water and dust ingress and IK09 for impact resistance. Surge protection is included as standard. Warranty coverage is provided by LED Lighting Supply; refer to documentation for terms and duration.
