The mercury vapor ballast is a device that works with mercury vapor lamps. The arc in a high-pressure mercury vapor lamp (HPMV) produces lines of varying energy in the ultraviolet, blue and yellow portions of the spectrum. A mercury vapor lamp is a gas discharge lamp that uses an electric arc through vaporized mercury to produce light. no detectable UVC or non-terrestrial UVB (wavelengths below 290nm). no detectable UVC or non-terrestrial UVB (wavelengths below 290nm). The extensive use of the mercury vapor lamp depends entirely upon the versatility of the mercury vapor as regards pressure, temperature, voltage and other characteristics, each change resulting in a lamp of different spectral quality and efficiency. no detectable UVC or non-terrestrial UVB (wavelengths below 290nm). The 6035 Hg(Ar) Lamp is insensitive to temperature. The mercury vapor arc gives visible spectra of green, yellow and violet. ... Transmittance is measured at 254 nm for low-pressure or LPHO lamps and over a wider spectrum of wavelengths (200–300 nm) for medium-pressure lamps. Mercury vapor lamps used in fluorescence microscopy usually have life spans of 300 hours, and as they approach the end of their life span, at 200 hours, exhibit output fluctuations primarily as a result of “discharge point shift” caused by cathode fatigue. This spectrum has: typical features of a mercury vapour lamp: extremely discontinuous spectrum ("spikes") very unlike sunlight. H2. COM. Typical emitting species are noble gases like helium (He), neon (Ne), argon (Ar), krypton (Kr) and xenon (Xe) as well as metal vapors like sodium (Na), cesium (Cs), mercury (Hg) and cadmium (Cd). 99 LP lamps operate at about 40°C and have one useful disinfection output peak at 254nm. Allow a break of at least 10 minutes be-tween successive periods of operation. This spectrum has: typical features of a mercury vapour lamp: extremely discontinuous spectrum ("spikes") very unlike sunlight. The basic parts of a typical mercury lamp are shown in Figure 1. Mercury Vapor lamps feature low initial cost, but have higher operating costs than HPS or Metal Halide due to its lower efficiency. Spectrum - UV in more detail. Mercury-Vapor Lamp. OSRAM 80W MERCURY VAPOUR LAMP. The lamp gets its state of its operational stability. At low pressures the output is predominantly in the ultra-violet, but as pressure increases self-absorption here results in the visible green, yellow and violet lines becoming relatively stronger.
