Energy Star
(Requirements for light sources)

The inside of an integrating sphere is the key area with regard to capturing and reflecting radiated energy from a light source.  The coating or material that forms the inside of an integrating sphere must uniformly distribute radiated energy and remain stable over time.  Click here for more information.

The integrating sphere size you use will be based on the range of light sources to be tested.  The larger the sphere, the greater the range of sources that can be tested.  There are, however, tradeoffs. Click here for more information.

One of the key advantages of integrating spheres are their ability to collect the total output of a device under test.  Light sources with highly divergent beam patterns must be handled differently than those with narrow patterns.  Click here for more information.
