Key Steps to Retrofit Streetlights with LEDs:
LED retrofits lower energy bills, improve reliability, and support cleaner lighting solutions. Proper planning, compliance, and maintenance ensure long-term success.
Careful planning is essential to define the scope of your retrofit project, address potential challenges, and ensure the LED upgrades are both efficient and cost-effective. A solid plan helps you select the right systems and schedule installations with confidence.
Start by conducting a detailed inventory of your streetlights. Document the location and key attributes of each fixture, and consider using GIS mapping tools to streamline this process. This step is especially important since many utilities lack complete or accurate records of their assets. Once the inventory is complete, assess the condition of the fixtures and their mounting styles. This evaluation helps determine whether to opt for lamp replacement, retrofit kits, or complete luminaire replacement.
Here’s a breakdown of the retrofit options:
| Retrofit Option | Installation Effort | Cost Level | Best Use Case |
|---|---|---|---|
| Lamp Replacement (TLEDs) | Low | Low | Simple fixture upgrades |
| Retrofit Kit | Medium | Medium | Custom or ornate fixtures |
| Complete Luminaire Replacement | High | High | New construction or major overhauls |
For fixtures that are difficult to replace - like decorative post tops or specialized parking lot lights - LED retrofit kits are often the best solution. Retrofitting typically involves removing components such as sockets, tombstones, ballasts, and reflectors before installing the new LED kit.
Energy audits are key to understanding your current setup. These audits measure energy consumption, lamp wattages, operating hours, and maintenance costs. Light analysis, on the other hand, helps evaluate illumination levels and distribution patterns, identifying areas where lighting may be insufficient or excessive.
"We conduct comprehensive energy audits to model precise efficiency improvements. Through meticulous analysis, we develop detailed models to showcase the projected efficiency improvements, helping clients make informed decisions towards sustainable lighting solutions."
Using LED savings calculators and photometric studies, you can estimate potential energy savings and design optimal LED layouts. Many organizations report energy savings of 50–80% after switching to LED lighting. Additionally, these audits help establish key performance specifications, such as lumen output, color temperature, beam angle, and energy efficiency requirements. This information is essential for selecting components and creating a project timeline.
To ensure compliance and take advantage of financial incentives, review local building and electrical codes, lighting standards (such as those from IESNA), and permitting processes. Collaborating with local authorities is critical for meeting utility requirements, safety standards, and any city-specific regulations regarding light intensity, color, or fixture design.
Rebates and tax deductions, such as Section 179D, can significantly improve the financial outlook of your project. Federal programs may also provide additional funding for municipal retrofits. Companies like Luminate Lighting Group specialize in navigating these opportunities, assisting with prequalification, paperwork, and ensuring timely reimbursement.

Consider these key points when planning your schedule:
Lastly, define the project scope clearly and plan separately for design, fixture procurement, and labor to ensure smooth execution.
Once you’ve outlined your retrofit plan, the next step is selecting LED components that work seamlessly with your current infrastructure. Picking the right LED retrofit kit is a critical part of any streetlight upgrade. The right choice ensures compatibility with your existing setup, meets safety standards, and optimizes both performance and energy efficiency.
Start by identifying your fixture type. Whether you’re dealing with cobra head streetlights, acorn-style fixtures, or shoebox designs, each type requires specific mounting solutions and wiring configurations. For instance, cobra head retrofit kits often include mounting brackets and wiring harnesses designed to fit directly into the existing housing.
Choose a kit with the appropriate wattage equivalency. An LED kit should deliver the same - or better - lumen output at a lower wattage. For example, a 150W high-pressure sodium fixture can typically be replaced with a 50W LED module. Make sure the kit’s mounting options align with your fixture’s dimensions and socket type. Some kits allow for a simple swap with minimal rewiring, while others may require more significant electrical adjustments. Additionally, confirm that the existing housing can handle the new voltage requirements and dissipate heat effectively to ensure long-term reliability.
Once you’ve identified the right kit, gather all the components needed for a smooth installation.
A complete LED retrofit typically includes the following key elements:
It’s crucial to select components that meet established safety and performance certifications. This not only ensures compliance with local regulations but also makes you eligible for rebates and other incentives. Look for products with the following certifications:
In addition to certifications, municipal codes may impose specific requirements. These could include maintaining a color temperature range (typically 3,000K to 4,000K for streetlights), ensuring proper cutoff angles to minimize light pollution, and achieving uniform photometric performance. Meeting these standards not only simplifies maintenance but also streamlines warranty claims.
Warranty coverage is another important consideration. Most LED modules and drivers come with warranties ranging from 5 to 10 years, helping to reduce maintenance costs over time.

Once you've carefully planned and selected the right components, follow this detailed guide to safely install energy-efficient LED retrofit assemblies for reliable, long-term performance.
Safety should always be the top priority when handling electrical work, especially with streetlights that run on higher voltages. Start by disconnecting power at the breaker panel and following lockout/tagout procedures. Use an insulated tester to confirm there's no voltage present.
Equip yourself with the necessary personal protective equipment (PPE), such as insulated gloves, safety glasses, and a hard hat. If you're working on streetlights, you'll also need proper access tools like ladders or bucket trucks rated for the height of the fixtures.
Gather essential tools, including insulated screwdrivers, wire strippers, socket wrenches, and weatherproof connectors. Keeping your tools organized and within easy reach will make the process much smoother and safer.
Once safety measures are in place, you can proceed to remove the old components.
If the fixture has been in use recently, allow it to cool completely before starting - high-pressure sodium and metal halide lamps can retain significant heat. Carefully remove the fixture cover or lens and place it in a safe spot to avoid damage. Label all wires during removal to make reconnection easier later.
Begin by disconnecting and removing the old lamp, followed by the ballast and any related wiring. Take photos or notes to document the original wiring setup for reference.
Remove any reflectors or optical components that won't be compatible with the new LED retrofit kit. Some kits are designed to work with existing reflectors, while others come with their own optical systems.
Dispose of the removed components responsibly, especially ballasts, which may contain hazardous materials. Be sure to follow local disposal regulations. Keeping a detailed record of the removal process is helpful for maintenance and compliance purposes.
Follow the manufacturer's instructions to mount the LED retrofit kit securely. Most kits use spring arms, clips, or mounting brackets designed to fit snugly into the existing fixture housing. Proper alignment of the LED assembly is crucial for even light distribution - misalignment can lead to dark spots or uneven illumination.
Match the wire colors and use UL-listed, weatherproof connectors to secure all connections. Ensure all wire splices are insulated and sealed with waterproof tape or gel-filled connectors to protect against moisture and corrosion.
Connect the LED driver to the power supply, checking that all connections are tight and secure. Loose connections can cause flickering, performance issues, or premature failure. Use UL-listed connectors and weatherproof junction boxes where needed.
To maintain the fixture's weatherproof rating, install any required gaskets or seals. Apply gaskets or silicone sealant around any openings in the fixture to prevent water from seeping in. Moisture is a leading cause of LED failures, particularly in outdoor applications like streetlights.
For example, the City of Arlington, Texas, successfully completed a large-scale LED streetlight retrofit project, achieving energy and operational cost savings of 40–60%. Their success was largely due to meticulous attention to installation details, including proper weatherproofing and thorough documentation of each retrofit.
With the LED assemblies securely in place, you’re ready to move on to testing and verification.
Once the LED retrofit assemblies are installed, it's time to confirm that everything is functioning properly. Restore power at the breaker and check for power at the fixture. Turn on the LED streetlight and ensure it illuminates correctly. Look for even light output across the area and watch for any flickering, which could indicate connection problems or an issue with the LED driver.
If your retrofit includes features like photocells or dimmers, test them to ensure they respond appropriately to changes in light conditions.
Document important details such as the fixture identification number, LED kit model, installation date, and any warranty information. Taking photos of the completed installation can also be helpful for future reference.
If the system includes smart controls or monitoring features, test their functionality as well. Many modern LED streetlight systems offer wireless connectivity for remote monitoring and control, so verify these capabilities during the testing phase.
