How are these lights holding up for you? Samething here, saw them advertised on CL $499 for 650 watts seems like a crazy good deal. How's the manufacturing look? Still holding up and running correctly?
.
To be frank with you, these lights are really awesome!
I finished building out my first real room and just bought 16 more of the 650-Si model. Of course, as soon as I bought them, they released two new models, which I wasn't told anything about but whatever. I'm super happy with these lights.
I've been averaging 2.5lbs a light on 4x4 tables in coco using Jacks nutrients.

Just pulled my first harvest after 8 weeks 5 days two pounds out of four plants not bad. Especially considering I underfed them and burned them slightly with a experiment putting the light at 1050 setting. Using the controller with it gives you dawn and dusk settings which I like. I get to the garden when the lamp is at 50% and it's easier to work for 15 to 30 minutes with it dimmed.

During flower do you have it cranked to 100? Curious, just started four seedlings under my new e680
I start my plants in the flower Tent at 700 setting 30" off the canopy, after a couple of weeks I have raised the level 5% every 3 days and lower the light to 22". Having it higher gives you a better perimeter light dispersion.
