Grow Light, Grow Light Bulb, HPS Bulb, MH Bulb -For Commercial applications: Sinowell high-pressure sodium lamps were developed primarily for their energy efficiency. Mercury and sodium vapors in the ceramic arc tube produce a yellow/orange light with extremely high LPW performance and exceptionally long service life (up to 40, 000 hours). High-pressure sodium lamps render colors poorly, which tends to limit their use to outdoor and industrial applications where high efficacy and long life are priorities.-For Hydroponics: These lamps are red/orange in the spectrum. They are the best lamps available for secondary or supplementary lighting (used in conjunction with natural sunlight or metal halide lighting). This type of light promotes flowering, budding, and fruiting in plants. It is ideal for Greenhouses growing applications.
