I just did a test recently....2 4x4 tents. 1 400w hps, 1 extreme flower 180w. Strain was thc bomb. The results were surprising. The 11 band makes a big difference. The ext led did a damn good job. I set up a flood and drain table recently (using sun leaves rocks), currently running some blueberry trainwreck under 600w hps, but I plan on swapping up my lights, buying another extreme diamond 200 and putting both above the f & d table. Enough to perform better than a 600w hps, while supporting less heat, less water evaporation, lower profile, and it'll look crazy technological, lol. The new 11 band with better angle lenses are legit for smaller spaces/home grows. Imo can now perform at the level of hid lights if used properly.
