50 Watt LED Street Light | 8000 Lumens | 5000K | 100V-277V | Type 3 | Photocell Optional

Product Overview

This 50 Watt LED Cobra Head Street Light is designed for street, roadway, and municipal area lighting. It delivers 8000 lumens at 5000K, with selectable color temperatures available. The fixture operates on 100V-277V and is compatible with standard pole mounting. Typical installations include neighborhood streets, municipal roadways, and campus road networks, often as a direct replacement for 150W metal halide fixtures.

The fixture features a Type 3 distribution as standard, with optional Type 2, 4, or 5 optics. A photocell option is available for dusk-to-dawn operation. The housing is constructed from aluminum alloy with a tempered glass lens and polycarbonate optics, suitable for outdoor environments requiring robust, weather-resistant lighting.

Core Performance and Output

This fixture outputs 8000 lumens at 50 watts, providing 160 lumens per watt efficiency. The Type 3 beam pattern is suited for roadway and street lighting, offering broad lateral coverage. Color temperature options include 3000K, 4000K, and 5000K, with a CRI of 70+ for general outdoor visibility.

Electrical performance is stable across 100V-277V input, with 1-10V dimming capability. The fixture is designed to replace 150W metal halide units, supporting mounting heights typically between 12 and 20 feet. Excessive output may occur at lower mounting heights, and uniformity can be reduced if spacing exceeds recommended pole distances for the selected optic.

Adjustability and Control Options

The fixture supports 1-10V dimming for integration with external controls or adaptive lighting systems. A photocell option is available for automatic dusk-to-dawn operation, reducing manual intervention for on/off scheduling. Optic selection (Type 2, 3, 4, or 5) allows adaptation to specific roadway or perimeter layouts.

Color temperature can be specified at order, but is not field-selectable. No onboard motion sensor is included. The fixture is compatible with standard pole arms and mounting hardware for cobra head luminaires.

Longevity and Reliability

L70 rated life is 131,000 hours, supporting long-term deployment with minimal maintenance. The fixture includes surge protection rated at 4kV line-line and 6kV line-earth, suitable for outdoor electrical environments.

IP66 ingress protection and IK09 impact resistance support reliable operation in exposed locations, including areas subject to wind-driven rain and incidental contact. The fixture is ETL listed and rebate eligible.

Build Quality and Physical Characteristics

The housing is constructed from aluminum alloy with a black finish. The lens is tempered glass with polycarbonate optics for impact resistance. The fixture measures 21 x 10 x 6.1 inches and weighs 12.5 lbs, supporting standard pole mounting.

EPA rating is 1.6, suitable for most single-fixture pole installations in low to moderate wind zones. The fixture is designed for outdoor use, with all components sealed against dust and water ingress.

Where This Product Fits Best

This cobra head LED fixture is intended for outdoor roadway and area lighting in municipal, campus, and private environments. It is commonly deployed on local streets, neighborhood roads, and perimeter drives where moderate output and controlled distribution are required.

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

Environmental characteristics include full weather resistance (IP66), impact protection (IK09), and suitability for pole mounting in outdoor locations. The fixture is not intended for high-mast or high-output roadway applications.

Installation and Long-Term Use

The fixture mounts to standard pole arms using industry-standard hardware for cobra head luminaires. Weight and EPA are compatible with most existing poles rated for single fixtures in the 12?20 foot mounting height range. Installation requires line voltage (100V-277V) and can accommodate photocell wiring if dusk-to-dawn operation is specified.

Routine maintenance is minimal due to the sealed housing and long LED life. Lens cleaning and periodic inspection of mounting hardware are recommended. Surge protection is integrated, but additional protection may be required in areas with frequent electrical disturbances.

How This Fixture Is Commonly Used

Typical mounting heights range from 12 to 20 feet, depending on pole spacing and required light levels. Fixtures are often spaced 2 to 3 mounting heights apart for uniform roadway coverage. Type 3 optics are standard for street and roadway applications, with alternate optics used for perimeter or irregular layouts.

Higher output per fixture can reduce the total fixture count but may increase glare if mounting height is too low or pole spacing is excessive. Photocell control is commonly used for automatic operation in municipal and campus settings.

Safety, Certifications, and Warranty

This fixture is ETL listed. It is IP66 rated for water and dust ingress and IK09 rated for impact resistance. Surge protection is included as standard. The product is rebate eligible where applicable.

Warranty coverage is provided by LED Lighting Supply. Refer to documentation for terms and conditions.
