High-pressure sodium (HPS) -- a high-intensity discharge lamp
that uses sodium under high pressure as the primary light-producing element.
Fluorescent and other high-intensity discharge lamps
may also be brought to the collections.
The report does not include analysis of any other type of lighting system, such as high-intensity discharge lamps
or incandescent bulbs.
IIHS focused on the issue as automakers shift to LED or high-intensity discharge lamps
for headlights instead of traditional halogen lamps, and use new technology for curve-adaptive headlights that turn based on the direction of the wheels.
Two-dimensional streaming flows in high-intensity discharge lamps

Previously, the facility used 400-Watt high-intensity discharge lamps
, which were upgraded to the Digital Lumens 10,000-lumen intelligent LED fixtures with integrated occupancy sensors in every fixture.
Lamp technology changed over the years from fluorescent T12 to T8 and high-intensity discharge lamps
to more efficient types of HID (ceramic metal halide for example).
Tibbetts: All fluorescent and most high-intensity discharge lamps
contain a small amount of mercury, a naturally occurring element necessary for the energy-saving attributes of these lamps.
There are limited numbers of complete LED headlamp systems on the road, as most are paired with high-intensity discharge lamps
According to the Commission, savings under the first measure for fluorescent lamps, high-intensity discharge lamps
and related ballasts and luminaires could be up to 15% of the equipment's current usage.
The system uses powerful, high-intensity discharge lamps
to flood the inspection zone with light.
