VIVOSUN 400 Watt High Pressure Sodium HPS Grow Light BulbYour #1 Choice for Indoor Grow

VIVOSUN HPS grow light bulb can produce a very balanced and efficient spectrum for plant growth. VIVOSUN HPS lamps have higher luminous efficiency than ordinary bulbs, and they have stronger penetrating power and long service life. It emits a red and orange spectrum that is among the most energy-efficient sources of indoor lighting and extends the growing season. It can be used through the vegetative, flowering and fruiting stages, and the yellow spectral output makes them optimal for flowering.

  • Please be aware that grow light bulb is a consumable product. Regardless of HPS, MH, LED, Fluorescent or the incandescent light bulb, the fact that the total lumen (brightness) will decrease in time.
  • For an optimized growing condition, it is strongly recommended to change your grow light bulb after 12 months of continuous use.
  • Note: The trigger voltage of our ballast is 7000V, and output frequency is 100K. If your ballast cannot reach the standard, then our bulb cannot be lighted up.

HPS bulb compatible with electronic and magnetic ballasts

  • VIVOSUN dimmable electronic digital ballast is the best choice for high pressure sodium grow light lamps.
  • The dimmable setting of ballast should be the same watts as the bulb when starting, or your bulb may not be lighted up. The extra setting is to adjust the brightness (lumen) of the bulb. Different lumens have different effect on the plants.
  • The ballast can't ignite lamps when it is hot. When reigniting the lamp after shutting down, please wait several minutes to give time for the lamp to cool down.
