Sol-Digital HPS 400W

The Sol-Digital 400w HPS lamp is a dual-spectrum lamp that is good for both the vegetative growth stage and for flowering plants. The lamp produces a high level of photosynthetically active radiation (PAR). This is light in the right spectral regions to provide the energy your plants need to form sugar from water and CO2 in the surrounding atmosphere.

These lamps also have improved stability even if the ballast is dimmed over varying output effects. Can be used on both magnetic and digital ballasts.
