Truth about HPS

Truth about HPS

HPS Bulbs use various gases to produce the spectrum ranges in its wheelhouse. Sodium, Mercury, and Xenon are the main gases within these bulbs. Sodium by itself produces a mostly yellow spectrum range, which is why HPS are extremely heavy in this range of wasted light. It is then mixed with impurities to produce other colors of the PAR range such as Mercury, which is responsible for the limited Blue range in HPS bulbs.
High Pressure Sodium Light Contain a small amount of toxic mercury. The mercury inside the bulbs is a hazardous materials that can present a waste disposal issue at the end of light’s life. Broken bulbs release a small amount of toxic mercury as a gas and the rest is contained in the glass itself.
