VIVOSUN 600 Watt High Pressure Sodium HPS Grow Light Bulb. High PAR Enhanced Red and Orange Spectrums. 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. 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.
VIVOSUN single ended HPS bulbs must use E39 lamp base fixtures. VIVOSUN provides you with the premium hydroponics equipment and services. It is our commitment to be the best indoor gardening and hydroponic store that you can trust.
