To elaborate lol. I've been running on two 100w SF lights since July. They are decent starting lights. I just got my Mars TSW2000 and it is awesome, I unboxed that yesterday and got it all set up. I love that I can put my controls and/or drivers outside of the tent. The functionality of the dimming on each is the same, but it cannot be separately mounted with the SF. I did also just get the HLG 100R as well, just put that one up today. Another solid choice, though it is not dimmable. It is super light weight though, which is nice.
I ended up putting the HLG in my 2x2, and moving the two SF in with the Mars light in my 4x4, cause why not lol.
