How dare you suggest he do his own homework... Can't you just tell him what the best light is without knowing his budget or size space he's trying to cover.Pick any light, read the specs on it. Then research what those specs mean. Then research which lights offer the highest spec in your price range. That’s how I break everything down. The world is a fraction of a second away with a Google search. Find the rabbit hole. Then enjoy your journey down it. Understanding what makes a light good to me is better than knowing a list of good lights.
Nice...I was looking at the 420...elected to go smaller so I don't have an excuse to buy another, larger tent. Went with an HLG to keep the 3x3I just bought a roi-e680 with the master controller, it's a very nice light.
