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.
Tenders are invited for The contract will cover pick-up, transportation, and recycling of used fluorescent lamps and used high-intensity discharge lamps
(high pressure sodium, mercury vapor and metal halide), ballasts, computer monitors and components, and other similar item
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
. Phys Fluids.
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.
