The EYE Hortilux Dual Arc 62800 bulb is a combination of the Hortilux Super HPS and the world class spectrum of Hortilux Blue in one lamp. The result of this combination is more compact plants and vigorous flower and fruit production without the need to purchase a Metal Halide and a HPS lamp separately. Dual Arc is the Best, all-in-one grow light. Use with Magnetic Core and Coil ballasts only.
