Low pressure mercury fluorescent lamps are commonly called tube lights.
Low pressure mercury lamp price.
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.
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.
Mercury lamps get dimmer over time and rarely burn out so it is wise to replace them and restore light level.
The average life of tube lights is about 5000 hours and also they are very cheap hence they are very popular.
The lamps can be constructed to emit primarily in the uv a around 400 nm or uv c around.
The clear mercury bulb has a bluish green appearance and the deluxe white has a higher color rendering.
Hg2 low pressure mercury lamps from heraeus noblelight have a highly stable output predominantly at the 253 7 nm mercury line.
Amalgam lamps yield up to three times the uvc output over standard lamps of the same length.
The power ratings are from 4 watt to 125 watts.
Amalgam lamps use a mercury amalgam mix to control mercury vapor pressure.
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.
Other lines which total 20 of the output are at 313 365 404 and 435 nm.
Nyc subways were still using original mercury arc rectifiers to convert ac to dc power up until the end of the 20th century.
Right around 1900 the mercury arc rectifier was developed this luminous device was very important for power conversion.
Mercury vapor lamps feature low initial cost but have higher operating costs than hps or metal halide due to its lower efficiency.
The main peak is between 310nm and 480nm and it.
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 spectrum of the lamp is continuous from near ultraviolet to far ultraviolet.
They are available in lengths from the very small at 150 mm to up to 2400 mm.
In low pressure mercury vapor lamps only the lines at 184 nm and 254 nm are present.
