We haven't seen many blackstar ion grows around these parts. blackstars were pretty popular back in 2011-2012 but were never considered to be top of the line, more like a one of the better bargain buys, not using name brand chips and having mediocre build quality. After that, they came out with the chrome series, which i heard both positive and negative reviews about, but was still considered an upgrade and improvement over the previous generation blackstars. This is the next evolution of their chrome series. I would like to get confirmation as to what CREEs they are using, asking for model/bin information.
It's just the 10w's they are saying are CREEs. And I'm pretty sure those are the 4 leds spaced between the 4 clusters. The others in the clusters, what they call 6w's, are unconfirmed. That is something I'd want to look into as well before buying.
Other than that, I'm sure it will work just fine. Might require being repaired at some point in the future, but it looks pretty modular so they may even send replacement parts and instructions to do a home-fix which is a good thing. A lot of companies with the cluster layouts do the same thing. It also means it could be upgraded too in the future as better leds are available.
It just comes down to a matter of whether or not you feel like it's a good deal for the money. I'd suggest shopping around a bit, look at other online journals and seeing what they use and their results are, calling some companies up to get a feel for who you are giving your money, and then make your decision as to whether this is the light you want and the people you want getting your money.
Good luck.
