I currently have a China 110kh 1000w ballast and it’s messing with my ec monitor, it’s not a huge deal as I just compensate in my head for it. I’m running it remotely, and I know that’s not the best but it’s how I’m set up. I have come to the conclusion I just need something better. Besides the RF interference, I swear my light is dimming and doing stupid shit, hard to tell, bright is bright, you can see it on the wall reflections though, almost like someone is playing with the dimmer (which seems to work half the time) I have eye balled phantoms and am curious as why I’m seeing vivosun 1k ballasts rated up there. Anyone using something they love for a 1k DE? Took a search around but not much recent talk on it that I saw. This ballast I’m using is mid priced, thought I would be ok. I’m down for a low frequency ballast as well, just need a strong one regardless, flower time is coming. 110-240 either or, I’m equipped.
