No experience with those. I did purchase a GrowLightScience Progrow1800 670w light. It sells for 420 bucks. It's a fantastic light. I ran 5 autos in 3 gallon pots using coco and perlite... using floraflex FullTilt nutes. With the light at 80% 540w.. this yielded me 24oz. It is a fantastic light for 420 dollars. I highly recommend it if you can find it.
Great customer service. The led driver failed, the over nighted a replacement it also failed they over nigted another replacement driver and turns out it was my electric outlet and the surge protector I was using. I switched outlets and got a new surge protector and it's worked flawlessly.
For 420 bucks your getting 670 true watts and even coverage it's truly hard to beat.
