Insane how much these lights went up! I purchased the 32 Watt for $129 on 7/18/2023 and now the same light is $179 on 9/13/2023. I was thinking of purchasing more of the fluval lights, but that's a $50 price increase in two months! The light itself is a good light, I like the features, including the bluetooth phone app. But, I'll watch it for a bit, maybe this is some kind of temporary price bump for the holiday rush ahead. I can buy hygger lights for under the price increase of $50 from Fluval. Gee Willikers

29 Gallon tank with low to med light plants seem to work well- thought I needed 2 lights but so far seems fine with 1

Happy with these lights overall. I bought four of the 32 watt lights for my 90 gallon / 340 liter tank (48"x18"x24"). It's a deep tank with a cross bar, so I opted for four shorter lights vs. longer. First picture shows how I've configured them on the tank.

My biggest issue is with the app. I love being able to control all my lights via one app. The only issue is that the the slider bar that is used to set the light schedule times in "Pro"mode is awful. I carefully slide until I get to the desired time like 09:00, then when I lift my finger it shifts to 09:02 or 08:58. It's minor, but when setting 4 separate lights, I prefer to have them all change at the same time. I finally found a workaround by taking a screenshot of the factory light settings, then deleting and recreating the time markers. When you create a new time marker, the time can be set using a different selector tool that's much easier to use. The good news is that once you get one light set, you can use "Save As" then export it to your other lights, so now I have all four lights on identical schedules.

The "Auto" mode is much easier to configure, but only allows four times to be set while "Pro" offers 10. I like the "Pro" because it allows me to set a "low intensity" period in the middle of the day where the lights are dimmed for a while.

One other thing that isn't really an issue (just surprised me) was the size of the power supplies (see last two pictures). Based on the label, it looks like these can get pretty hot. So far, even after a full day of operation mine are just warm not actually hot, but it's something I'll keep an eye on.

The sunrise/sunset and moonlight features are a great addition to the tank. My plants are growing extremely well. Be aware that a power outage will make you have to reprogram the timer settings, but since I have the settings on the app, it just reloads what you have saved. You will have to reload it if the power goes out, as the light will default to "on". A little expensive, but it works great!

This light is the best! I love the app and that I can control & program the lights from my phone. I tried an different brand of light prior to this unit and wish I'd saved my money and bought this first. This unit is a little more expensive but we'll worth it!
