This is a powerful light. I have 2 smart 8s in a 4x8 , 60-80% is all you need. If you are shopping best bang for the buck . You can stop shopping. MedicGrow is the best

I laid my hps lights to rest and ordered these bad boys and boy o boy best choice I ever made for my ladies!! Fast shipping I received my lights 7 days after ordering. Beautiful design very solid light. I was shocked how big and heavy these lights are in comparison to my basic1000w hps vivosun light lol, not complaining one bit just saying. My first time cutting the LEDs on just to see them lit up made me go HOLY. S@#T!!! Lol it's literally like having a heatless sun in ur possession, PLENTY OF LIGHT. Like I said no heat at all u can literally touch the diodes, but not for long just for a second or two they are kinda warm just holding them lol. The screen display and the veg/flower button is a nice touch. The timer has a sunrise and sunset program built into it meaning when you turn the timer on the lights go dim then eventually gets brighter over time and then dims back down then off for sunset, cool touch excellent piece of technology I can't say enough nice things about it so far, it's like going from a flip phone to a iPhone 13. I will return in two months to write another review after my next grow is finished to tell you guys how much more these lights improved my harvest compared to my hps, I have very high hopes.
