Quanta Pro's are no joke and you get a lot for the money. They're basic on/off, so no dimming, but honestly, it's not necessary at all. As
@Smite mentioned, their spectrum, blending and number of diodes far exceed the closet competition's lights. If I would go all LED again, it would be a mix of Quanta Pro's, Kessil and Reefi Uno's. I think the ATI Straton is killer fixture, but no LED fixture is worth that much money, no matter how much you think you're saving with energy. It's a shame that there's no single fixture out there that does what the old school fixtures (mh/T5) do. You would think by now, that someone would figure out how to get it done, but they're all doing pretty much the same thing or sticking to their guns thinking they are good enough or worse, leading the pack.
Why can't they give us coverage, spectrum and shimmer, all in one package? I do like the GHL Mitra's, but their software is the most ancient tech out there design by Commodore 64. I'm still using old school tech like
@Smite, mh/quanta pro and couldn't be happier.
