These standards are accredited by ANSI, which is a private non-profit organization that oversees 

the development of voluntary consensus standards for products, services, processes, systems, and 

personnel in the United States. The organization also coordinates U.S. standards with international 

standards so American products can be used globally. 

Candela – A unit of measurement of the intensity of light that is, power emitted by a light source  

in a particular direction.  

Lux – The unit of luminous flux in the International System, equal to the amount of light given out 

through a solid angle by a source of one candela intensity radiating equally in all directions. 

Lumen – A unit of measurement of the amount of brightness that comes from a light source. 

Lumens define “luminous flux,” which is energy within the range of frequencies we perceive as light.

IP (Ingress Protection) – Ingress Protection (IP) ratings specify the environmental protection the 

enclosure provides. The IP rating normally has two numbers (IPXX). The first number represents 

protection from solid objects or materials (dust) where the second number represents protection 

from liquids (water). With the IP rating IP 54, 5 describes the level of protection from solid objects 

and 4 describes the level of protection from liquids.
