I really excited! The biggest change I saw before lights out was the spectrum, that picture looks kinda blue, but these are nowhere near the electro Windex color I had going on beforeI couldn't believe the change in my tank after replacing my vipars. Turns out, I had a bunch of weird hotspots as well. My replacement light has way better spectrum & coverage & is more even in general. Corals really responded well to the change. I'm sure you'll see the same
