315w CDM 4000k Bulb
4000k is used for the Veg/Growth stage of your plant growth.
Very powerful lights that offer your plants a high level of useable plant light for maximum growth.
Creates a much broader light spectrum than standard bulbs such as MH and HPS.
These bulbs are compatible with any 315w reflector, and can only be used with standard reflectors with the use of an e40 CDM adapter.
