LEC 315W Easy Garden CDM-930 Bulb - 3,000K

Ceramic-Discharge Metal-Halide (CDM) bulbs provide a light spectrum much closer to natural light than traditional HID systems. This bulb generates a higher level of usable light (photosynthetically active radiation) and its 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 the highest quality product. NOTE: The lamp should never be turned off within 2 minutes of being switched on, until it has been running for at least 10 hours. If this occurs, you must wait 1 hour before turning the lamp back on.
