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. |
