GENERAL SERVICE LAMPS
Governor’s Office of Energy

In August 2020, the Director of the Governor’s Oce of Energy adopted regulation R100-19 pursuant to
Nevada Revised Statute (NRS) chapter 701.260 as amended under Assembly Bill 54 (2019). The regulation sets
a minimum standard of energy eciency of 45 lumens per watt of electricity consumed that must be produced
by General Service Lamps sold in Nevada on and after January 1, 2021.
WHAT ARE GENERAL SERVICE LAMPS?
General Service Lamps (GSLs) refer to lighting applications traditionally served by general service
incandescent lamps (GSILs), also known as "A-type" bulbs. The majority of lighting in a residence is covered
under the new standard and denitions, including:
• General Service Incandescent Lamps (GSILs)
• Compact Fluorescent Lamps (CFLs)
• General Service LED Lamps
• General Service Organic LED Lamps
• Reector Lamps
Traditional incandescent
bulbs waste a
lot of energy as
heat to create
light. They last
about one year, on
average.
Improved halogen
incandescent
bulbs use up
to 30 percent
less energy than
traditional light
bulbs and can
last three times as
long.
Curly compact
fluorescent
bulbs use up
to 75 percent
less energy than
traditional bulbs
and can last for
10 years. But they
can be slow to
brighten and have a
colder light quality.
LED bulbs use up to 85
percent less
energy than
traditional
bulbs and can
last for 25 years,
without some of
the drawbacks of
compact
fluorescents.
COMMONLY FOUND GSLs COVERED UNDER CHANGES
WHERE ARE GENERAL SERVICE LAMPS
USED?
These are the most commonly used lightbulbs, and
they are generally pear-shaped. The majority of
lighting found in a residence are considered GSLs, and
some common uses are table side lamps and daily-use
light xtures.
WHY DID THE REQUIREMENTS CHANGE?
As lightbulb eciency improves and energy ecient
lightbulbs become more aordable, GSLs with
eciency below 45 lumens per watt are increasingly
rare. According to a report published by the Appliance
Standards Awareness Project (ASAP), replacing
inecient lightbulbs could result in household savings
of $81 each year.

WHAT ARE THE TECHNICAL SPECIFICATIONS OF A GENERAL SERVICE LAMP?
“General service lamp” means a lamp that:
• has a medium, candelabra or intermediate screw base
• is able to operate at a voltage of 12 volts or 24 volts, at or between 100 to 130 volts, at or between 220 to
240 volts, or of 277 volts for integrated lamps, or is able to operate at any voltage for nonintegrated lamps
• has an initial lumen output of greater than or equal to 310 lumens (or 232 lumens for modied spectrum
general service incandescent lamps) and less than or equal to 3,300 lumens
• is not a light xture
• is not an LED downlight retrot kit
• is used in general lighting applications
