To be honest,I have never heard of the Migro Cobs so I’ve just had a look through their website. I like the versatility of the mounting bracket and I’m sure they work well as a grow light (similar technology) but they are considerably more money. I don’t know if they would be that much better (if at all) than the Autocobs from cobshop.net. What I do know is that from the Autocob owners here on AFN, I have heard very good reviews. For me, they will cut my lighting power bill in half and provide a better light over my blurples. At the price and quality, I don’t believe I could go wrong.
