The following glossary of terms will help you when selecting lamps in this section.
Within each product line, lamps are divided into families – within these families,
lamps are listed by wattage. The Product Description can be used as a quick
reference to each product’s attributes. Where Rated Life is stated we refer to the
industry standard definition of how many hours of operation 50% of
a given installation will exceed.

Volts:
Lamp data
is based on
operation at
rated voltage
Rated Life:
The point in time when
50% of installed lamps
are still burning
