The very first thing to notice about the Cree 100W light is that it uses COB technology. This stands for Chip-On-Board and it uses 9 diodes or more to produce a massive amount of light in a small unit. Not only that, but the lumens output is much higher than a standard unit due to the multiple diodes being used in the area.

Despite the massive amount of power and light, the cooling fan keeps the unit at a very comfortable 77F (or 25C). This means it will only be slightly warm to the touch. Not only that, but the fan is incredibly quiet, ensuring that you can grow your plants in peace.

Just hang it from the included hook, turn the switch on and go on with your day. The LED light will look after your plants and ensure that they grow big and strong.

Overall, this unit is small, but it gives you a massive amount of power and it can be installed anywhere. Its light weight and advanced lighting ensures that this is one of the best 100W LED grow lights available for home users.
