InterLux Super 400W HPS Grow Lamp - E39 Base - 400W

Red-Shifted Light for Indoor Flowering - 400W HPS

Flowering rooms need a light source whose output suits the flowering stage. This high pressure sodium lamp shifts its spectrum toward the red, which is why growers use HPS during flowering. It screws into a standard E39 socket, so it replaces a worn lamp without a fixture change.
