High Pressure Sodium Lamp Lifetime

Dimming is limited to about 50 of full light output.

High pressure sodium lamp lifetime.

Two varieties of such lamps exist. Cri and reduced lamp efficacy. 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. While effective optical efficiency of led lights currently in the united states is about 621m.

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. 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.

High pressure sodium applications hps lamps unlike most metal halides do not require enclosure except to prevent moisture from accumulating on the lamp. 1 high power lamps 250w. 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. Set your store to see local availability add to cart.
