I think the cree replacement is only swapping the white LED's as there are still blue and violet 3W's. $190/26 XPG's = $7.30 per XPG R3.. and you don't get the replaced semiled's$5.94 more per 3w LED assuming also that they leave the 30w Semileds alone.
Looks like they didn't cost adjust for the replaced 3w Semileds
On the RC forum, someone stated that the two 30w are also changed out to four 15w.I think the cree replacement is only swapping the white LED's as there are still blue and violet 3W's. $190/26 XPG's = $7.30 per XPG R3.. and you don't get the replaced semiled's
I paid about 6.25 per XPG from a groupbuy, and mine are the better R5's too!
I think either they miscalculated or they simply don't want to make any modifications
It may be the difference between having 2 30W LED's on each 160 and having 4 on the 230 maybe? That 93 Cube is 30 inches wide so with the two fixtures about 8.5" apart it puts each pair of 30W LED's about 11 inches apart. On the 230 the 4 30W Chips are a lot closer to each other. I guess it is possible at least??I like the color of the tank with 2 160W but the bigger tank with the 230W looks a bit too yellow. I wonder why that is since they both use the same 30W white and similar white to blue ratio.
