Venture High Pressure Sodium


SKU: N/A Category:


Venture High Pressure Sodium (HPS) lamps promotes flower onset and production and is, therefore, more suited to the flowering/fruiting phase.

Proper lighting is a key ingredient in promoting robust, healthy growth as well as meeting the needs of various plant growth phases through optimized spectral outputs. Specifically tailored for the hydroponic and horticultural industries.


HPS bulbs are the most efficient bulbs that are commonly used by the hobby gardener. They are high in the red and yellow parts of the spectrum and low in the blue, this imitates the fall sun. Because of this spectrum some plants that are grown with HPS lights only can grow elongated and rather leggy, while many other plants are not effected by the light spectrum. For plants that normally bud and flower in the fall this is usually the light of choice because the light spectrum promotes flower production.

HPS bulbs are made out of a translucent ceramic arc tube containing a mixture of sodium, mercury and xenon gas. This arc tube is suspended in a outer glass shield (bulb). HPS bulbs range in power from 35w to 1000w, with the 250w, 400w, 600w and 1000w being the most popular for indoor horticulture.

HPS bulbs should be changed out after about 24 months. The bulbs slowly lose their brightness over time and to maintain good light quality the bulbs must be changed before the end of their rated life.

250W  HPS Venture = 30 000 Lumens

400W  HPS Venture = 45 000 Lumens

600W  HPS Venture = 90 000 Lumens

Ballast is required to fire lamp

Remember: When handling grow lamps to ensure you don’t leave fingerprints on the glass as this will impair the performance of the lamp. It is best to use a cloth when handling grow lamps.
