Very nice lights
I bought these to replace my failing AI Prime HD and absolutely love it. I love the way they look, they are affordable, shimmering. The light spread is super even and my corals are doing great. The app is pretty easy to learn as well. Once you set up a program the lights aren't always using WiFi or anything super techy, Just Bluetooth.

Good lights, horrible app
The app is very confusing and inconsistent. The lights change color when connecting. The blue slider and white sliders are miscolored (blue = white light, backwards) and the red slider doesn’t appear to do anything. One light turned off based on the schedule, the other remained lit overnight. You can’t control the two lights separately.I’m hoping I can dig in more and get what I need out of them, but it’s looking like a return so far.

Nice Lights
Very nice lights. Only wish the mount set up could be a bit more clearer and pictured better on the instructions. Ability to control the lights via app is a +plus for me! The other cool thing I love is the smooth day/night transitions. I'm quite surprised about the lack of reviews this lights have but in my personal opinion, I can't complain; satisfied.

Came Broken
When I unboxed it I noticed it was broken. The screw that goes into the light was broken inside of the light. I can’t use it now since i can’t hold up the light at all.

Works Great
It seems to work amazing. My fish seem to be very happy with it. It’s very easy to use. It required some assembly but not a big deal and it came with all the tools. I would definitely recommend my tank is a 30 gallon tank.

Cheaply made.
Light bracket broken when I received it. Can’t attach to T bar. Cheap material. Lights are cool looking. After one day the unit stopped working. Being sent a replacement, will update thereafter

High quality product with excellent customer support
I am very happy with this quality and sturdy product. I tired many different types of so-call " high quality " aquarium light ( those cheap Made in C ) but all broke within few months if not weeks. I use Cetus 2 SS for my 22 gallon fresh water planted tank. My plant, shrimps and the fishes all love it. I have also emailed their support team to see if there is any QR code for fresh water setting and they immediately reply with the relevant QR code and the detail instruction on how to modify it in order to make it fresh water friendly. Made in Taiwan is just so much better.
