• Blue and red spectrums available for vegetative growth and flowering respectively

125 Watt Blue CFL Lamp - 6400 Kelvin

125 Watt Red CFL Lamp - 2700 Kelvin

How to Use

As useful additions, we offer a standard CFL Lead and Lampholder (an E40 lampholder attached to a mains cord - no reflector) and the CFL Reflector (a version of the BAY6 Reflector that includes a mains lead and E40 lampholder). If you simply want to use CFL lamps as a supplementary light source, then the CFL Lead & Lampholder is a good choice, whilst either our CFL BAY6 Reflector or Sun Mate Grow CFL Reflector are better options if these lamps are to be used as the primary light source.

Could you give me an idea of how much less these cost to operate compared to a ballasted HPS?
A 125W Eco Light will consume 1/2 the power that a 250W HPS will. However, on a Watt for Watt basis, the HPS is more efficient, as it produces more lumens per Watt. A 250W HPS lamp will produce 33000 lumens, whereas 2 x 125W Eco lights will produce 24000 lumens.
