The recently introduced 600 Watt HPI-T Metal Halide light is designed to work with a wide range of sodium lighting ballasts, such as the ballasts supplied by Esoteric Hydroponics. Metal halide lights are typically used to create a simulated autumn. High pressure sodium lamps are sufficient as general purpose hydroponic lighting, although metal halides are more efficient towards the end of the growing cycle. If you can only afford one type of light, get high pressure sodium - but ensure that the hardware interoperates with metal halide lamps.

Please note that the 600W Metal Halide lamp is too large to be used with the 600W water cooled lighting. Please ask Esoteric Hydroponics staff about 600 Watt lighting, especially the new 600 Watt Metal Halide [MH] bulbs.
