What’s up my overgrow growers! I am bring a good news!
Mars Hydro are now offering our COB led grow lights “Buy ONE Get ONE FREE” promotion! Last around 1 week, if we sold out earlier, it might ends sooner. 
Yes, you are right, not buy one light, send one pair of yoyo or a pair of glasses, but buy one COB light, you get two COB light, that means, spend the same amont of money, you get two lights. If you don’t need that much light, get a friend to buy together, and you will just pay around 120USD for each light. :hippy::hippy: Nothing like this before, and might not happen in future. :headbanger::headbanger::headbanger:
If you DIY the light, what might cost ? ?
A Cree CXB 3590, around 50USD/pc
Meanwell driver: around 30USD/pc
Heatsink: around 30USD/pc
The suppliment Cree and Osram chips: 20USD total
Shipping: 20~30USD total if within your country
Only these, you will need to pay at least around 150~160USD in total
Plus: no ETL certificate, no complete design and some other small components, and handling fees.Because Mars hydro also are losing money to do this promotion, just to make our support growers happy.
