versus what
and that 11% is RELATIVE efficiency
so lets just say your OG setup is 50% efficient at chip level, it would be 50* 1.11= 55.5%, not 50+11=61
I dont understand why cree has become stagnant on their products.they used to be at the forefront of leds and had record after record for efficiency. Now companies like citizen keep improving to the point where there isnt any reason to buy cree cobs other than for their binning of high end cobs. They have extremely good efficiency in the DD bins. Only problem is that i dont believe they make those in anything other than 5000k-6500kcree seems to have abandoned the cob market for the most part.
even in CXBs heyday citi was better (the -058s at least). since gen5 048-1818 has been above cxb and thats been out for almost 2 years
