Product arrived in sturdy packaging inside and out. I have been using an S360 for just over a year and have obtained optimal results per watt. I ordered the S900 because I am expanding my grow area. The combined footprint of the S360 and S900 will cover it. I have no doubt that the S900 will provide the same optimal results throughout the growth cycle. The IR diodes are a unique feature not found on many grow lights, and (based on my experience with the S360) they do, in fact, enhance resin production.
