Our LED Retrofit Kits include conversion options for HID, metal halide, high-pressure sodium, and fluorescent fixtures. Product types include high bay, shoebox, parking lot, wall pack, street light, canopy, strip light, troffer, and tube-style retrofit options. Kits replace lamps, ballasts, and related internal components while retaining suitable existing fixture housings. Available models vary by wattage, lumen output, beam angle, color temperature, voltage, driver type, dimming, controls compatibility, mounting method, and fixture compatibility. Voltage configurations include 120V, 277V, 347V, and 480V. Some models support occupancy sensors, photocells, time clocks, dimming, or building controls. Products carry UL, ETL, or CSA safety listings depending on the model, and many are DLC or DLC Premium listed.
Common applications for these retrofit kits include warehouses, manufacturing areas, industrial spaces, shops, gymnasiums, parking lots, streets, exterior walls, security areas, and other existing commercial lighting installations. High bay kits are used in high-ceiling spaces, while shoebox and parking lot kits convert pole-mounted fixtures. Wall pack kits replace internal components in existing exterior wall-mounted housings. Fluorescent retrofit options cover linear fixtures, strip lights, troffers, and tube-style conversions. These kits can retain existing poles, brackets, ceiling mounts, fixture locations, and housings when those components remain in use.
What Are LED Lighting Retrofit Kits?
LED lighting retrofit kits are designed to upgrade existing HID, metal halide, high-pressure sodium, or fluorescent fixtures without replacing the entire fixture housing. Instead of removing the full fixture, a retrofit kit replaces the lamp, ballast, and related internal components with LED technology when the existing housing is suitable for reuse. Retrofit kits can be a practical option for commercial, industrial, warehouse, parking lot, street, canopy, wall pack, high bay, shoebox, and other existing fixture types. They allow many facilities to improve energy efficiency, reduce lamp and ballast maintenance, and modernize older lighting while keeping existing poles, housings, mounts, or ceiling infrastructure in place.
Selection and Installation Note: Product specifications, wattage, lumen output, beam angle, color temperature, voltage, driver type, dimming, controls compatibility, fixture compatibility, thermal performance, mounting method, certifications, and warranty coverage vary by model. Confirm the selected product specification before ordering. For LED retrofit kit installations, fixture modifications, ballast removal, direct wiring, high-voltage systems, outdoor fixtures, or code-sensitive applications, verify requirements with the facility team, local inspector, project specifier, or a licensed electrical professional.
Different Types of LED Retrofit Kits
LED retrofit kits are available for many older lighting systems. The right kit depends on the existing fixture housing, lamp type, ballast, mounting method, voltage, thermal space, and the light distribution needed after conversion.
| Retrofit Kit Type | Common Use |
|---|---|
| Metal halide retrofit kits | Used to convert older HID fixtures in warehouses, parking lots, gyms, industrial spaces, and exterior area lighting. |
| High-pressure sodium retrofit kits | Used to upgrade older street, area, security, and outdoor fixtures where improved light quality and efficiency are desired. |
| High bay retrofit kits | Used in warehouses, manufacturing areas, shops, gyms, and other high-ceiling spaces where existing fixture housings can be reused. |
| Shoebox and parking lot retrofit kits | Used to upgrade older pole-mounted parking lot fixtures while keeping the existing fixture housing or pole infrastructure. |
| Wall pack retrofit kits | Used to convert older exterior wall packs where the housing remains in usable condition. |
| Fluorescent retrofit options | Used for linear fluorescent fixtures, strip lights, troffers, and tube-style conversions depending on fixture type and wiring method. |
When LED Retrofit Kits Make Sense
Retrofit kits are most useful when the existing fixture housing, mounting hardware, wiring access, and fixture location are still suitable. They can be a good option when a facility wants to improve lighting performance without replacing poles, brackets, ceiling mounts, or exterior fixture housings.
- Existing housings are still in good condition: The fixture body, mounting hardware, lenses, gaskets, and wiring access should be suitable for reuse.
- Fixture replacement would be difficult or expensive: Retrofit kits can reduce disruption where fixture housings are hard to remove or mounted high above the work area.
- The site has many similar fixtures: Facilities with large fixture counts may benefit from a repeatable retrofit approach.
- You want to keep existing poles or mounts: Retrofit kits can often work with existing pole-mounted or ceiling-mounted infrastructure when properly specified.
- You want to remove HID lamps and ballasts: Many retrofit kits eliminate older lamps, ballasts, capacitors, and ignitors from the fixture.
When Full Fixture Replacement May Be Better
Retrofit kits are not always the best choice. If the existing fixture is damaged, corroded, poorly sealed, too small for heat management, or no longer appropriate for the space, a new LED fixture may be a better long-term option.
| Existing Condition | Better Option to Consider |
|---|---|
| Damaged or corroded housing | Consider a new LED fixture instead of reusing a failing fixture body. |
| Poor gasket or water intrusion | Outdoor fixtures with water damage may need full replacement to restore proper environmental protection. |
| Limited internal space | Some housings may not have enough room for the LED engine, driver, heat sink, or wiring. |
| Wrong distribution pattern | If the old fixture housing no longer provides the needed light pattern, a new fixture may perform better. |
| Old or unsafe wiring | Electrical conditions should be reviewed before any retrofit. Fixture replacement or rewiring may be required. |
Benefits of LED Lighting Retrofit Kits
- Reuse existing infrastructure: Retrofit kits can allow facilities to keep existing housings, poles, brackets, ceiling mounts, or fixture locations when suitable.
- Energy efficiency: LED retrofit kits can reduce energy use compared with older HID, metal halide, high-pressure sodium, or fluorescent systems, with actual savings depending on wattage, controls, operating hours, and existing conditions.
- Reduced maintenance: LED conversions can eliminate routine lamp and ballast replacement common with older lighting systems.
- Instant-on operation: LED retrofit kits reach usable output quickly compared with HID lamps that require warm-up or restrike time.
- Improved light quality: LED options are available in different color temperatures and beam patterns to better match the application.
- Controls compatibility: Some retrofit kits support dimming, occupancy sensors, photocells, time clocks, or building controls depending on the model and installation.
- Lower disposal complexity: LED retrofit kits do not contain mercury like fluorescent lamps, though removed HID or fluorescent lamps and ballasts should still be handled according to applicable disposal requirements.
How to Choose the Right LED Retrofit Kit
Choosing a retrofit kit starts with the existing fixture, not just the old wattage. The housing size, mounting method, voltage, available space, thermal conditions, and desired light distribution all affect which kit will work.
| Selection Factor | What to Confirm |
|---|---|
| Existing fixture type | Confirm whether the fixture is a high bay, wall pack, shoebox, canopy, street light, flood light, troffer, strip fixture, or another housing type. |
| Existing lamp and ballast | Confirm whether the old system is metal halide, high-pressure sodium, fluorescent, or another source, and identify existing ballast components. |
| Internal fixture space | Confirm the housing has enough room for the retrofit kit, driver, heat sink, wiring, and any mounting hardware. |
| Thermal management | LED kits need proper heat dissipation. Enclosed or poorly ventilated housings should be checked for thermal suitability. |
| Voltage | Confirm input voltage and driver compatibility, including 120V, 277V, 347V, 480V, or other project-specific requirements. |
| Lumen output | Compare delivered light output, not just wattage. Old HID lamps may have lost substantial output before replacement. |
| Beam angle or distribution | Choose optics that match the application. A high bay, parking lot, wall pack, and canopy fixture may need different distributions. |
| Controls | Confirm dimming, photocell, occupancy sensor, time clock, or building automation compatibility before ordering. |
Retrofit Kit Installation and Compatibility
LED retrofit kits should be installed by a qualified electrician. Most kits require removing or disconnecting older lamp and ballast components, mounting the LED engine or module, securing the driver, wiring the fixture, and confirming grounding and controls.
- Disconnect and verify power before installation.
- Confirm the existing fixture housing is suitable for reuse.
- Remove or disconnect HID, fluorescent, ballast, capacitor, ignitor, or other components as required by the kit instructions.
- Confirm the LED kit fits inside the housing with proper clearance and heat management.
- Verify voltage, grounding, wiring method, and controls compatibility.
- Confirm lenses, gaskets, doors, and covers close properly after installation.
- Label modified fixtures where required by product instructions or local requirements.
Common LED Retrofit Kit Mistakes
- Choosing only by old wattage: Old wattage does not tell you fixture output, distribution, lumen depreciation, or what the space needs now.
- Ignoring fixture condition: Damaged, corroded, or leaking housings should not automatically be reused.
- Skipping thermal review: LED drivers and modules need proper heat management inside the existing housing.
- Assuming every kit fits every fixture: Internal space, mounting method, door clearance, and wiring access vary by fixture.
- Not confirming voltage: Retrofit kits must match the building voltage and electrical system.
- Forgetting controls: Photocells, sensors, time clocks, and dimming systems should be confirmed before ordering.
- Keeping failing components: Old ballasts, capacitors, ignitors, sockets, wiring, or lenses may need replacement or removal depending on the kit.
- Using the wrong distribution: A retrofit kit that fits physically may still produce the wrong beam pattern for the application.
