Sodium Mercury Vapor Light

An amalgam of metallic sodium and mercury lies at the coolest part of the lamp and provides the sodium and mercury vapor that is needed to draw an arc.

Sodium mercury vapor light.

The mercury vapor lamp would behave on a high pressure sodium ballast so i screwed it in the socket the lamp started up red and warmed up to a cool white color as expected howeven a minute after reaching full brightness the arc extinguishes i ve observed this closely and the lamp cycles on the 70 watt hps ballast why is this so. I rated the fixture and the seller excellent. I would definitely purchase it again. I ll cover other hid lighting technologies including sodium and metal halide next week.

High pressure sodium lamps render colors poorly which tends to limit their use to outdoor and industrial applications where high efficacy and long life are priorities. This fixture came complete with minor assembly. Mercury vapour lamp is quite suitable for lighting applications. Will it make any difference with the bulb type.

Maintaining a vacuum is difficult oxygen and other gasses can seep in over time. The sodium vapor strikes an arc over 240 c. Yes and no i think they have the large base but a sodium will not work in a mercury vapor but a mercury vapor will work in a sodium fixture i put up a sodium light i did not really want the orange light and all my other mv are white so i put a mv bulb in a sodium fixture been working every since. Light is produced when electric current is passed through mercury vapor in a sealed glass bulb.

The higher the lamp power the higher will be the amalgam temperature. This is because most of the light emitted from a sodium vapour lamp is concentrated in the yellow part of the visible spectrum around 580 590 nm. I bought a fixture that has a mercury vapor bulb but i prefer to use a high pressure sodium bulb. All of the new fixtures give off a yellow light and i like the bright white.

This is because the mercury vapour lamp can feed almost the entire visible region 380 780 nm of the human visual system. The mercury helps add a blue spectrum light to the pure yellow of the sodium.

Mercury and sodium vapors in the ceramic arc tube produce a yellow orange light with extremely high lpw performance and exceptionally long service life up to 40 000 hours.

After my mercury vapor light of 30 years failed i looked for a replacement fixture but not find one locally.

The temperature of the amalgam is determined to a great extent by lamp power. Feit electric 70 watt ed17 shape clear high pressure sodium e26 medium base hid light bulb 1 bulb model lu70 med hdrp view the hid light bulbs 20 97 20 97.
