Finally the lighting solution revolution has arrived. Following a three year period of research and testing The MINIMAX 150 micro-processor ballast has now completed trial testing, qualifying the Minimax 150 for CE registration. Fully tested and registered the Minimax 150 is now ready for the market.

Running at less than 0.65 amp we feel that this little unit will revolutionize indoor grow lighting. No longer do we have to compromise with CFL bulbs or LED panels. The MINIMAX 150 operates with either Metal Halide (blue vegetative) or, High Pressure Sodium bulbs (red flowering)...

Why Lumens don’t mean anything to plants

Light Measurement for Horticultural Applications Why is the lumen useless for horticultural applications? The answer to that lies in the definition of the lumen. What does it measure? The lumen is a SI unit that measures light according to how effective it is at stimulating human visual response.

Let's look at some definitions: Lumens are a measure of radiant flux (watts), but with the wavelength restriction. In the real world, very few light sources are monochromatic at 555nm, so to assign lumen ratings to lamps, it is necessary to weigh the light emitted at other wavelengths. This is calculated by...
