So, what is it? (Or was her electrician maybe off base?)

Thanks guys,

Jeff

I did a quick Google search and found this:
http://www.energy.ca.gov/2005publica...6_Lighting.pdf


It talks about "luminaires" and "occupant sensors". Is "luminaire"
Californiaese for "light bulb"? Sounds like it is a code requirement.
California is the place with overloaded elec. demands in hot weather,
right?


From further down in the same document:

*******************

A luminaire is the lighting industry’s term for light fixture. A
luminaire consists of the housing, power supply (ballast), lamp,
reflector, and in some cases a lens. A lamp is the lighting industry’s
term for a light bulb. Luminaires can be designed to be recessed into
the ceiling, suspended by a rod or chain, or surface mounted
on the wall or ceiling.

A high efficacy luminaire is one that contains only high efficacy lamps
and must not contain a conventional (medium) screw-based socket.
Typically, high efficacy luminaires contain, pin-based sockets, like
compact or linear fluorescent lamp sockets, though other types such as
screw sockets specifically rated for high intensity discharge lamps
(like metal halide lamps) may also be eligible for exterior use.

Luminaires with modular components that allow conversion between
screw-based and pin-based sockets without changing the luminaire housing
or wiring shall not be considered high efficacy luminaires. These
requirements prevent low efficacy lamps being retrofitted in high
efficacy luminaires. Also, compact fluorescent luminaires with
permanently installed ballasts that are capable of operating a range of
lamp wattages, the highest operating input wattage of the rated
lamp/ballast combination must be use for determining the luminaire wattage.

There are two qualifying requirements for a high efficacy luminai
that the lumens per watt for the lamp be above a specified threshold and
that electronic ballasts be used in certain applications.

So, I guess the guy who decided to put those motion detectors in our
office building's bathrooms over ten years ago was way ahead of his
time. G
