Overview
The 4ft Magnetic LED Retrofit Kit offers a flexible, energy-efficient solution for upgrading fluorescent troffers and linear strip fixtures. Designed to replace 32W T8 fluorescent tubes, the kit features two magnetic light bars that securely attach to existing fixtures for quick, tool-free installation. Using the provided screws, the bars can also be mounted to non-metallic surfaces. The included driver allows for selectable wattage (36W, 50W, 60W) and CCT (3000K, 4000K, 5000K), enabling precise customization of light output. With a frosted lens that ensures uniform 110° light distribution, this retrofit maintains the appearance of fluorescent lighting while delivering superior energy savings. Ideal for offices, schools, and healthcare facilities.

A product that bears an ETL-Certified label has been evaluated by a Nationally Recognized Testing Laboratory (NRTL) and meets national product safety standards. An ETL certification is accepted in the U.S. and in Canada.
Class 2
Class 2 power supplies must meet the National Electric Code (NEC) and Underwriters Laboratories (UL 1310) standards for wiring requirements and power limitations of AC/DC power supplies to minimize shock or fire risks. All Class 2 power supplies must meet the NEC overcurrent protection and wiring sizing regulations. They must be constructed with ‘In-Wall’ rated wiring for permanent installation inside walls or floors, where they may be surrounded by insulation. These wiring requirements help prevent cracking or melting of the wire, which could cause a fire hazard. These power supplies must have a maximum power capacity of 100 VA and cannot exceed a 30 VAC or 60 VDC output, minimizing the risk of electric shock or overheating from excessive currents.
The DesignLights Consortium® (DLC®) partners with energy-efficiency groups and utility companies to establish a set of standards for commercial LED light fixtures. The product is tested and must meet quality, energy-efficiency, and performance requirements to be added to the DLC's Qualified Products List. For more information, click here.

Certifications/Compliance
Certifications/Compliance
Standards and certifications comprise a vast number of companies and compliances that serve specific purposes—primarily addressing safety, environmental impact and energy efficiency, and sanitation. They are divided into categories for each product type and certification type to allow for very specific qualifications related to each product. When this system is being used as intended, it gives consumers, installers, suppliers, and anyone else that may be involved confidence that the product is safe and will work well in their application. The most common UL and ETL certifications relate to safety and installation, although they do also provide some sanitation-related certifications (using NSF standards). Another common certification body is the DLC, which specializes in certifying the performance of a light—mainly related to environmental impact and electrical efficiency.

Current Draw
Current Draw
Current draw is calculated using the following formula: W/V = A, where W = the amount of power your light needs (wattage), V is the electrical system voltage (e.g., 120V AC), and A = amps. An ampere or amp (A) is the standard unit for electrical current. A milliamp (mA) equals one-thousandth of an amp, or 1000 mA is equivalent to 1 A.
Choosing LED fixtures with the correct amperage ensures safe and proper operation, preventing damage or injury. We recommend having all electrical components and fixtures installed by a certified professional electrician or lighting technician in compliance with all relevant standards and regulations. |
