They are releasing a new dimmable version they will allow the t5’s to be run on two separate channels and it appears that there is only one cord for the entire fixture!! Both channels will be able to be ran independently through a controller.I love the Aquatic T5 Hybrid. So far so good and the fact that you can hook up with radions, hydras, ai primes and kessils is a plus! The only thing I didn't like was the power wire for T5s are on opposite ends of the fixture, but I was able to get an extension cord to make up for it.
