It says it is a 400 watt equivalent but only produces 18,000 lumens... a 400 watt HPS produces 50,000-60,000 lumens... I'm not so sure about these claims
Yeah thats true but the thing is the plant doesnt grow due to lumens. Thats a measurement of light thats only really applicable to how humans perceive light. Plants have a different standard to energy they need to grow and thats PAR and the true measurement of the lights need to be measured with a PPF meter.
