75 Watt Post Top LED Retrofit | 9750 Lumens | E26 Base | 5000K

Product Overview

This 75 Watt Post Top LED Retrofit is designed for direct replacement of legacy HID lamps in post top fixtures, acorn globes, and decorative site luminaires. It delivers 9750 lumens at 5000K, providing high-output illumination for outdoor pedestrian areas and architectural sites. The E26 base and socket mounting allow for straightforward installation into existing fixtures without the need for extensive rewiring or fixture replacement.

Typical use cases include upgrading 250W metal halide lamps in municipal, campus, and park environments. The 360° beam angle ensures uniform light distribution in open areas, supporting both safety and visual comfort in pedestrian zones and decorative outdoor settings.

Core Performance and Output

This retrofit produces 9750 lumens at 75 watts, achieving an efficacy of 130 lumens per watt. The 5000K color temperature provides a neutral white light suitable for outdoor visibility and security. The 360° beam angle ensures even coverage in post top and globe fixtures, minimizing shadowing and dark spots in open areas.

At mounting heights typical for post top poles (10?16 feet), output is balanced for pathway, pedestrian, and site lighting. Excessive output may occur if installed at lower heights or in small enclosures, potentially causing glare. The retrofit is non-dimmable and operates on 100?277V circuits, supporting a wide range of site electrical conditions.

Adjustability and Control Options

This retrofit lamp is non-dimmable and does not include integrated controls. It is designed for on/off operation via standard circuit switching. There are no onboard sensors or networked control options.

Beam distribution is fixed at 360°, with no field-adjustable optics or shielding. Control strategies requiring dimming or occupancy response must be implemented at the circuit or fixture level, not within the lamp itself.

Longevity and Reliability

The rated lifespan is 50,000 hours, supported by a pure aluminum housing for thermal management and a polycarbonate lens for impact resistance. The lamp is designed for continuous operation in outdoor environments, with stable performance over time.

Reliability is enhanced by the use of quality driver components and a robust heat sink. The retrofit is suitable for year-round exterior use in post top and decorative fixtures, provided the fixture allows for adequate ventilation and is not fully enclosed beyond manufacturer recommendations.

Build Quality and Physical Characteristics

The lamp measures 5 inches in diameter and 10 inches in length, with a total weight of 3 lbs. The housing is constructed from pure aluminum for heat dissipation, paired with a polycarbonate lens for durability and light diffusion.

The E26 base supports direct socket installation. The retrofit is compatible with most open or vented post top fixtures designed for HID lamps. Fully enclosed fixtures may restrict airflow and are not recommended unless specifically rated for LED retrofits of this size and output.

Where This Product Fits Best

This retrofit is intended for outdoor decorative and pedestrian area lighting where legacy HID lamps are being replaced for improved efficiency and reduced maintenance. It is commonly used in:

• post top lighting
• decorative outdoor lighting
• pedestrian area lighting
• architectural site lighting
• park lighting
• campus lighting
• pathway lighting
• municipal decorative lighting

Environments include municipal parks, campus walkways, public plazas, and landscaped pedestrian corridors. The lamp is suitable for outdoor use in fixtures that provide adequate ventilation and weather protection. Not intended for use in hazardous, marine, or high-vibration environments.

Installation and Long-Term Use

Installation is performed by removing the existing HID lamp and installing the retrofit into the E26 socket. In most cases, the ballast must be bypassed to supply direct line voltage to the lamp. The lamp?s physical size requires confirmation of fit within the fixture envelope before installation.

Long-term operation is supported by robust thermal management and a sealed driver compartment. Routine inspection of fixture seals and electrical connections is recommended to maintain performance. Lamp replacement intervals are extended compared to HID, reducing maintenance cycles in outdoor environments.

How This Fixture Is Commonly Used

Retrofit lamps of this type are typically installed at mounting heights between 10 and 16 feet, spaced 20 to 40 feet apart depending on site layout and required light levels. They are used in both single-head and multi-head post top fixtures along walkways, plazas, and site perimeters.

Spacing and layout are determined by pole height, fixture style, and target illumination. Higher output can reduce the number of fixtures needed but may increase glare if not properly shielded or if installed at lower mounting heights.

Safety, Certifications, and Warranty

This product is UL certified. It is eligible for utility rebate programs where applicable. The lamp is designed for safe operation in outdoor environments when installed according to manufacturer instructions.

Warranty coverage is provided by LED Lighting Supply. Refer to the product documentation for warranty terms and claim procedures.

Frequently Asked Questions

Q: What is the recommended mounting height for this retrofit lamp?

A: Typical mounting heights range from 10 to 16 feet for post top and pedestrian area lighting.

Q: Does this lamp require ballast removal before installation?

A: Yes, the existing ballast should be bypassed to provide direct line voltage to the lamp.
