Available in blue spectrum (6400K) for vegetative growth and red spectrum (2700K) for flowering, these lamps have inbuilt ballasts and a standard E40 screw fitting allowing the 125W version to be used with any reflector apart from the Diamond.
The 250W model is larger and as such requires either the High Output CFL Reflector or the CFL Pro Reflector. Both sizes of lamp can also be used with a simple four metre lamp lead.
As with all CFL lights, one of the key benefits (and key to success) is positioning them close to the plants, around 4 to 10 centimetres is the ideal distance, as the heat emissions are significantly lower than HID lamps.
If you are looking to use CFLs as an additional light source, its worth hanging them from a lamp lead to add some blue spectrum light as most plants respond well to this.
