NEMA Enclosure Types The National Electrical Manufacturers Association (NEMA) is a US Manufacturers Organization which actively promotes standardized product specifications for electrical apparatus. While NEMA does not actually test products, it establishes the performance criteria for enclosures intended for specific environments. NEMA standards describe each type of enclosure in general and functional terms, and specifically omits reference to construction details. In other words, NEMA specifies what an enclosure [...]

FAILURE, RELIABILITY, AND LIFETIME “Reliability” and “lifetime” are not synonyms. They are two separate and equally useful values reported by a component or subsystem manufacturer. A “failure” is an event which ends the life of a specific product or component, but may need definition if that end is not immediately evident, as is the case with lumen depreciation. Usually a luminaire or lamp design will encompass a number [...]

Who can perform testing? LM-80-08 testing should be performed by EPA recognized Laboratories. Only [...]

LM-79 is a procedure of photometric testing for LED luminaires. It’s an IESNA document that the photometric laboratories must follow to test the LED luminaires. Basically it tells you how the luminaire must be tested and what information must be included in the photometric report. A photometric report according to LM-79 will contain the luminaire’s photometric data (lumens, vertical distribution of the lumens, color temperature…) and electric data (power, [...]
