I just watched a review from Mr. Salt Water Tank about the controller for the AI lights. This is probably an older review but I think the controller works with the Hydra as well. Have they fixed the problem he reported? He said there are no batteries in the controller so it must be plugged in all the time. If for some reason the controller loses power or is unplugged, the lights stay stuck in whatever mode they were in at the time until you return power to the controller. So, if you were on vacation and the power went out while your lights are on at full power, they would stay that way until you caught it and fixed it. Is this true, or have they fixed that? Check out the link below. He covers this at the 3:40 mark.

Also, can these lights be run in series? If you buy three, can they all be run off of one controller? Thanks in advance.
