We stock a range of quality 400 watt hps and mh grow lights which includes ballasts, bulbs, reflectors and heat shields. HID (HPS and MH) lights are often used by growers because they provide excellent results in both vegetation growth as well as in flowering. Growers can easily produce commercial grade yields when using HPS lights. In terms of coverage area's - as a rough guide each 400 watt hps light will give a coverage area of about 0.8-0.9 meters.
