I just received the 550 V2 to test against a Hortilux 1000W HPS in a side-by-side. Unfortunately, I didn't receive it in time for the 2/1 flip so I'll be doing in in April.
In the meantime, I stuck it in my veg tent and it is pretty slick. Really low profile, BRIGHT white light, and it runs really cool compared to the HPS.
