Low Pressure Mercury Lamp Price

The spectrum of the lamp is continuous from near ultraviolet to far ultraviolet.

Low pressure mercury lamp price.

They are available in lengths from the very small at 150 mm to up to 2400 mm. Right around 1900 the mercury arc rectifier was developed this luminous device was very important for power conversion. The low pressure uv lamps also called germicidal lamps exploit uvc light to get the rapid sterilization of bacteria molds fungi viruses and microorganisms both in air and in water in this category of lamps about 40 of electricity is converted directly into uvc radiation with monochromatic emission at 254 nm for germicidal applications and at 185 nm for the oxidation of surfaces. In low pressure mercury vapor lamps only the lines at 184 nm and 254 nm are present.

Fused silica is used in the manufacturing to keep the 184 nm light from being absorbed. When used with the heraeus c430 power supply the line output is much higher than and the stability comparable to that of a deuterium lamp. Nyc subways were still using original mercury arc rectifiers to convert ac to dc power up until the end of the 20th century. Ots cst 5000 exposure lamp uv lamp 5000w ultra high pressure capillary mercury lamp exposure lamp ultra high pressure capillary mercury mercury lamp is a water cooled and instant on lamp type.

The power ratings are from 4 watt to 125 watts. Mercury vapor lamps feature low initial cost but have higher operating costs than hps or metal halide due to its lower efficiency. Rather than a cold spot the lamp s amalgam spot on pellet regulates mercury vapor pressure during operation and yields up to three times the uvc output of a standard low pressure mercury lamp of the same length. The lamps can be constructed to emit primarily in the uv a around 400 nm or uv c around.

Low pressure mercury fluorescent lamps are commonly called tube lights. In medium pressure mercury vapor lamps the lines from 200 600 nm are present. The average life of tube lights is about 5000 hours and also they are very cheap hence they are very popular. Our companies provide high quality spot amalgam and pellet amalgam lamps in standard and custom configurations.

These early low pressure lamps used a lot of mercury today s lamps use a tiny amount of mercury. Our low pressure pellet amalgam lamps function with equal efficiency in both horizontal and vertical operations. Other lines which total 20 of the output are at 313 365 404 and 435 nm. Amalgam lamps use a mercury amalgam mix to control mercury vapor pressure.

Mercury lamps get dimmer over time and rarely burn out so it is wise to replace them and restore light level. Hg2 low pressure mercury lamps from heraeus noblelight have a highly stable output predominantly at the 253 7 nm mercury line.
