High Pressure Sodium Bulbs - Free Shipping
High Pressure Sodium Lamps operate by igniting sodium, mercury and xenon gases within a sealed ceramic arc tube. They emit light energy in the yellow-red-orange regions of the spectrum; the red spectrum stimulates flowering and fruit production. Many indoor gardeners switch to sodium lamps when it is time to induce flowering or fruiting of their plants. One year warranty.
