A standard
mercury vapor lamp has 60 to 70 percent of its output below 340, and the black acts as a sponge.
Although the total spectral output of such a lamp is very similar to that of a standard
mercury vapor lamp, the spectral bands actually shift toward longer wavelength.
Fifty-three percent of the patients treated by ophthalmologists had used bed/booth devices, 17 percent had used reflective bulbs, 11 percent used
mercury vapor lamps, and 20 percent used unspecified UV devices.
Thus, a standard camera rated for incandescent light will have considerably less sensitivity when observing a scene lighted by
mercury vapor lamps.
Emerging lighting technologies - technology Electronic ballast based, Pulse start, Substrate materials, Laser lift-off, Temporary bonding, Binning, Surface texturing, Phosphor composition and deposition, High Pressure
Mercury Vapor Lamps, Low Pressure
Mercury Vapor Lamps, Tungsten photonic lattice, and others
UV LED lamps are alternatives to the
mercury vapor lamps that have been around for more than 130 years.
Through that work, the company generates a variety of hazardous wastes, including paint and solvent wastes, used oil, and used fluorescent and
mercury vapor lamps, according to the EPA
93 for the
mercury vapor lamps (Ravi and others 1993).
Additionally, the manufacture of general-purpose
mercury vapor lamps will be banned after January 1, 2016.
If you want even more functionality than the traditional PLC power supply provides, you may choose a new 27-step unit capable of up to 600w and running either Metal Halide or
Mercury Vapor lamps.
Generally, high-pressure sodium lamps are considered the most efficient with instant restrike capability; metal halide lamps provide the best color rendering for dramatic highlights and sports lighting; and
mercury vapor lamps, with very long lives, are preferred for landscape and sign lighting.
Many outdoor lighting security systems depend on
mercury vapor lamps.
