LEC Bulb 315w Easy Garden CDM-932 - 3,300K

Ceramic-Discharge Metal-Halide (CDM) bulbs provide a light spectrum much closer to natural light than traditional HID systems. These bulbs generate a higher level of usable light (photosynthetically active radiation), and their power can be observed with the naked eye. The bulb operates with reduced power consumption and radiant heat. Its spectrum allows for the cultivation of a product of the highest quality. NOTE: The lamp should never be turned off within 2 minutes of being switched on, until it has been operating for at least 10 hours. If this occurs, you must wait 1 hour before turning the lamp on again.
