Measuring the efficiency of the new Phillips leds

Today Roel from Phillips came and he helped us with the light measurements, with a spectral photometer. We could see the big difference between our chinese lamps and their lights. We proved that the efficiency of Phillips lamps is bigger than the others.

So take in to account that it's important if you don't have sunlight and you want your crops to grow fine it's necessary that you install proper lamps.
