Thank you for the clarification Happy. You pose a darn good question, where are those extra lumens coming from? If the BB bin has a color tint closer to green while the AD bin might be closer to red, that would explain the lumen difference and the CRi difference. Is there any indication in the part number that one is 50F (4 step) and the other 50H (2 step). There is also the possibility that they have different color tints AND that the BB bin is simply more efficient of an emitter.
