Mars II Led Grow Light 400
- Product Review (submitted on March 8, 2017):
Haven't started growing yet but mine arrived today and I'm impressed. Some of the labels English isn't the greatest but my model now has a switch for each light intensity. Each intensity runs one fan rather than both all the time so can be quieter as well as more efficient. I ran the light in a 2x2x4 tent for several hours with a 4in fan at it's lowest setting and there was no noticeable heat even directly in top of the unit, it was basically cool to the touch. Now I may have to find a way to to heat my tent because the lights are so cool!
Can't wait to start growing!
