High Pressure Sodium (HPS) lamps produce a strong red-orange spectrum, which is ideal for flowering plants. Some HPS lamps such as the Son Agro have 30% more blue than a typical HPS lamp, and Hortilux bulbs have 25% more blue. There also is the Hortilux Dual Arc lamp which contains a 400 MH and a 600 HPS in the same lamp for the ultimate full spectrum experience.
