I just wanted to weigh in and offer my $0.02
After reading this thread I figured, eh why not give them a try.
I have a 180 mixed reef and am trying to swap over from a T5 to LED. The prospect of AI Hydra was looking to be $2,000-2,500 and Radions were out of the question for what I am willing to spend.
For $180 I figured the 150 was worth a try
I ordered one to see if I liked it, and I liked it a lot. It is a bit clunky to use without the controller. So I went ahead and ordered 2 more lights and the controller.
Game Changer!
You can set 6 lighting points and it transitions the light automatically by 1% at a time between the lighting points, so it is as smooth as can be.
I own several AI Hydra 16/32, and the drawbacks are that you cannot set each light channel independently, you can only control the “white” and “blue” levels. However, the general settings they offer are fairly similar to what I have on my AI lights. Seeing how similar these lights are in output for a fraction of the cost, I am not at all disappointed in the result. I will update in a few months, but so far I am very happy with it.
