Metrolight- Positive - Efficient Building Systems As a developer of energy-efficient, networked lighting control systems that enable up to 70% energy savings, Metrolight is well-positioned to serve both the incumbent high-intensity discharge lamp
and the emerging LED market for industrial and street lighting applications.
Intertek examined and tested the UNIDIM ballasts, and found them to be in compliance with UL-1029, 1994 Edition, the standard for high-intensity discharge lamp
Two-dimensional streaming flows in high-intensity discharge lamps
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).
There are limited numbers of complete LED headlamp systems on the road, as most are paired with high-intensity discharge lamps
For headlamp applications, one solution could be more widespread use of high-intensity discharge lamps
, since they need a higher voltage anyway.
The issue centers around the fact that fluorescent and high-intensity discharge lamps
contain a small quantity of mercury.
Quantitative x-ray absorption imaging with a broadband source: Application to high-intensity discharge lamps
While mercury switches have virtually disappeared from convenience lighting applications in cars, the use of mercury is increasing in applications such as high-intensity discharge lamps
and backlighting applications in instrument panels.
5 Europe High-intensity Discharge Lamps
Market to 2020
High-Intensity Discharge lamps
include High Pressure-Sodium, Mercury Vapor, and Metal Halide lamps.
At present, energy savings based on conventional lighting technologies include compact fluorescent lamps (CFLs) with integrated electronics, advanced linear fluorescent lamps, halogen energy-saving lamps (HES) and high-intensity discharge lamps
, together with advanced control gear and light management systems.
