Hey,
No I don't think so, it is a constantly evolving thing though. Comparing the units from every year or so there is a considerable difference! I am no expert and this is just opinion but I think the cobs are really the thing I have been waiting for. I bought a few blackstar clones and have never really been happy with them, they are like smaller versions of the big Mars lights we have been talking about. I like the white light and spectrum they produce but I love the modular way that the "autocobs" are. That is real flexibility. I guess time will tell as far as how they produce. One thing for sure they will cost a lot less to run than my HID stuff! Here is a picture of my current setup with the cobs. Those are t5s in each corner, sunblasters with the nano reflectors.
