High Pressure Sodium Lamp Lifetime

1 high power lamps 250w.

High pressure sodium lamp lifetime.

The expected lifetime for high pressure sodium lights is longer than low pressure sodium lights. Two varieties of such lamps exist. Ballasts for discharge lamps. Dimming is limited to about 50 of full light output.

High pressure sodium lamps tend to produce a much whiter light but still with a characteristic orange pink cast. This makes hps lamps especially easy to use in many fixture types.

New color corrected versions producing a whiter light are now available but some efficiency is sacrificed for the improved color. A sodium vapor lamp is a gas discharge lamp that uses sodium in an excited state to produce light at a characteristic wavelength near 589 nm. Low pressure and high pressure low pressure sodium lamps are highly efficient electrical light sources but their yellow light restricts applications to outdoor lighting such as street lamps where they are widely used. High pressure sodium applications hps lamps unlike most metal halides do not require enclosure except to prevent moisture from accumulating on the lamp.

High pressure sodium lighting efficiency considering the loss of magnetic ballast lamps and optical channel utilization efficiency of the three factors if the overall efficiency by 0 55 meter the effective optical efficiency is about sodium 70 751m w. High pressure lights have a life expectancy of 16 000 to 24 000 hours while low pressure sodium lights should run for 12 000 to 18 000 hours. While effective optical efficiency of led lights currently in the united states is about 621m. Free delivery with 45 order.
