Envirogrow CFL product details:
Envirogrow compact fluorescent lamps are self ballasted low energy grow lamps that are available in a blue spectrum (great for propagation or vegetative growth) or red spectrum for supplemental flowering lighting. Envirogrow CFL's run much cooler than high powered sodium and metal halide lamps.
Envirogrow CFL's will fit in any
E40 lamp holder. Alternatively you can screw Envirogrow CFL's into a reflector and for best results you should use the
Sunmate CFL reflector which is custom designed to handle these bulbs. The sunmate is extra deep to handle the large size of the Envirogrow CFL's and the lamp holder is reinforced so as not to bend or break with the extra weight.
