Changes to Lighting Global testing: Transition to IEC 62257-9-5:2018 (ed.4)

In June 2018 the International Electrotechnical Commission (IEC) published a new edition of the test methods used for testing solar products, IEC 62257-9-5:2018 (also written as IEC 62257-9-5 ed. 4). It will take our program and the associated test labs some time to phase in use of this new document. This memo describes the associated … Read More

Human Health: LED Lighting, Insects, and Wavelength

This article examines the issue of insects attracted to lights in the nighttime environment and the risk to people from insects carrying diseases. A review of the current understanding is given, along with possible ways to reduce attraction, in the context of LEDs used in off-grid lighting products.  

Outdoor Cable Policy

The Lighting Global Quality Standards for Solar Home System Kits include a requirement that “Any outdoor cables must be outdoor-rated and UV-resistant.” This requirement goes beyond the Quality Standards for pico-products (off-grid products with peak power ratings less than 10 -15 W) and is based on the assumption that larger solar home system kits are … Read More

Product Support Expiration Policy

Results from the Quality Test Method (QTM) and Accelerated Verification Method (AVM) testing are used to determine if a product meets the Quality Standards. Test results are valid for two years. Their expiration date is typically set for the last day of the month, two years from the original test report date. Occasionally, there are … Read More

Policy for Renewing Test Results

Quality Test Method (QTM) tests are valid for a period of two years from the original test report date. To ensure continued support for another two-year period, these results must be renewed or updated, with the cost of testing borne by the manufacturer. To ensure continued support for another two-year period, these results must be renewed … Read More

Testing Similar Products Policy

Manufacturers often offer product models that are essentially variations of an existing product. In such cases, the Lighting Global Quality Assurance Program offers manufacturers the option of using full test results for at least one product, and targeted testing for the variant products. This option is provided as a service to manufacturers to help reduce … Read More

Product Sampling Policy

Goals and Rationale The Quality Testing Methodology (QTM) institutionalized through IEC/TS 62257-9-5 provides valuable third party information on product performance and quality to stakeholders across the value and decision chain in the off-grid lighting market. Proper sample procurement – the first step in the testing process – is critical for maintaining the fairness and credibility … Read More

Performance Reporting Requirements

This document provides guidelines for performance reporting requirements for all products that meet the Lighting Global Quality Standards. The performance reporting framework provides buyers throughout the supply chain with standardized information about key metrics to make purchasing decisions, while allowing manufacturers and suppliers the flexibility to provide this information in innovative and product-specific ways.
