Congratulations to your new light! I'm sure you will like it. Superior lights can be easily identified: They do not need fans (which only wastes energy, produces additional heat and noise and can and will break sooner or later). This means the manufacturer cannot use cheap, ineffective electronics and LED chips, so you get high end stuff like the Meanwell driver. Your MarsHydro will feel like a toy in some days. Of course the Quantum Boards are much more expensive, but they are worth every cent. I will follow this diary even more closely now, because Quantum Boards were amongst the lights I considered purchasing myself. Main reason to go with the Sanlights was the flexibility of multiple small ones and the feature of having the drivers outside of the tent.
