I love these lights. I have used it for 4 runs now, and my results get better as I am learning, so, had I had the experience on run one that I have after run 4, my original yield would have almost doubled so, it certainly was not the TS1000 that hindered my first run resulting in 122g from 3 autos. Anyhow, the TS1000 is a great light, love the dimming feature which is useful for the first week to 10 days, getting the vegging started, and then full power, faultlessly, throughout on a 20/4 on/off program. I really do think I should invest in a TS2000 now, for better coverage in my 80X80 tent.
