Hey, brothers
Some of our items are having a ‘buy one get one free’ promo, today is the last day. Don’t miss it if you are interested 
The chip of Cree 128 is Cree, each led has a reflector cup, thus it can max the light performance. 2 Cree 128 can cover a 4*4ft grow space very well.
ECO120 is the most effective one, epistar chip, 2*4ft coverage each !
COB uses Cree and Osram chip, two together can nicely cover a 2*3ft grow space, the main feature of it is no fan, and white spectrum .
Pro120 is similar to Cree 128, they both can cover a 2*4ft in flower. The difference is that Pro 120 chip is Epistar not Cree~~~
Btw, use our coupon ‘MarsHydro420’ can save an extra~~~
