High pressure sodium lamp lifetime.

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. Free delivery with 45 order. High pressure sodium lamps tend to produce a much whiter light but still with a characteristic orange pink cast.

While effective optical efficiency of led lights currently in the united states is about 621m. Vivosun 2 pack 400 watt high pressure sodium hps grow light bulb lamp high par enhanced red and orange spectrums cct 2100k ultra bright 55 000 lumens 4 4 out of 5 stars 443 24 85 24. Hydro crunch 1000 watt double ended hps high pressure sodium de grow lamp model d911009000 40 25 40 25. Two varieties of such lamps exist.

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. New color corrected versions producing a whiter light are now available but some efficiency is sacrificed for the improved color. The expected lifetime for high pressure sodium lights is longer than low pressure sodium lights.

1 high power lamps 250w. This makes hps lamps especially easy to use in many fixture types. Cri and reduced lamp efficacy. 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.
