Question 1

What is the 3G vibration rating LED street light?

Accepted Answer

A street light meeting the 3G vibration rating means it can withstand 3G vibration testing conducted according to the American National Standards Institute's ANSI C136.31 standard. This test involves 100,000 cycles in each of the X, Y, and Z planes at an acceleration of 3g (approximately 29.4 m/s²). This rating is primarily intended for luminaires installed on bridges and tunnels, simulating the vibrations generated by wind and traffic to ensure the luminaire can withstand these forces upon installation, guaranteeing safety and proper functionality. Other common street light ratings include 1.5G, 2.0G, and 3.8G.

Question 2

What are the other ANSI standards for lighting?

Accepted Answer

In addition to the vibration test standard ANSI C136.31, ANSI (American National Standards Institute) has also developed numerous lighting standards. These include ANSI/IES LM-79, ANSI/IES LM-80, ANSI/IES TM-21, ANSI/IES RP-8-22, ANSI/IES RP-6-20, ANSI C136.41, and ANSI C136.10. For example, LM79 tests the photoelectric parameters of lamps, LM80 measures lumen maintenance of LED chips, TM21 measures lumen maintenance of LED luminaires, RP-8-22 and RP-6-20 address road and sports court lighting, respectively, and ANSI C136.41 and ANSI C136.10 address NEMA sockets for streetlights.

Question 3

What’s the relationship between ANSI and NEMA?

Accepted Answer

ANSI (American National Standards Institute) is a non-profit organization responsible for managing and coordinating standards development in the United States. ANSI recognizes standards-setting organizations across various industries, such as NEMA and IESNA. NEMA stands for the National Electrical Manufacturers Association, while IESNA stands for the Illuminating Engineering Society of North America. NEMA has developed standards such as ANSI C136.41 and ANSI C136.10, which refer to NEMA sockets for LED road lights; IESNA has developed standards such as LM-79 and LM-80, which cover the lumen maintenance of LED lights.
