This standard specifies the energy efficiency limits, energy efficiency limits, energy-saving evaluation values, and test methods of non directional self ballasted LED lamps for general lighting. This standard applies to non directional self ballasted LED lamps for general lighting purposes with a rated power of 2W-60 W, a rated voltage of 220 V, and a frequency of 50 Hz, without external optical lenses. The following normative references are essential for the application of this document. For dated references, only the dated version applies to this document. For undated references, the latest version (including all modification orders) applies to this document. GB/T 20145 Photobiological Safety of Lamps and Lamp Systems GB/T 24824 Test Methods for LED Modules for General Lighting GB/T 24906 Safety Requirements for Self ballasted LED Lamps above 50 V for General Lighting GB/T 24908 Performance Requirements for Self ballasted LED Lamps for General Lighting GB/T 24908 Terms and Definitions GB/T 24908 defines and the following terms and definitions apply to this document. 3.1 The initial luminous efficiency for non directional self ballasted LED lamps for general lighting services is the ratio of the initial luminous flux to the measured power of non directional self ballasted LED lamps for general lighting services. 3.2 The minimum allowable values of energy efficiency for non directional self ballasted LED lamps for general lighting services
Function of testing report:
1. Project bidding: Issue authoritative third-party CMA/CNAS qualification report
2. Online e-commerce platform entry: Quality inspection report recognized by major e-commerce platforms 3. Used as a sales report: issuing legally effective testing reports to make consumers more confident 4. Papers and research: Provide professional personalized testing needs 5. Judicial services: providing scientific, fair, and accurate testing data 6. Industrial problem diagnosis: Verify the troubleshooting and correction of industrial production problemsBaijian and testing process:
1. Telephone communication and confirmation of requirements
2. Recommend solutions and confirm quotations 3. Mail samples and arrange testing 4. Progress tracking and result feedback 5. Provide reports and after-sales service 6. If urgent or priority processing is requiredTesting and testing characteristics:
