ANSI (American National Standards Institute)
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.
Glossary of Terms:
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.
