Fluval Aquasky 2.0 Bluetooth LED Aquarium Light – 18W, 24–36" | RGB + 6500K White | App Controlled with Weather & 24-Hour Light Cycle | IP67 Waterproof | Wide 120 Degree Light Spread

Very good light. I have it on my 55 gal cichlids tank. I was weary of having to use an app on my phone to control it but it was very easy to install the app and easy to use . It has so much more settings of color and brightness than other cheaper lights. It even has various cloud cover settings and cool storm settings with lightening. Its cost more than other lights but it’s worth it if u like a lot of different variations.

This light is perfect. So many color options as well as customizable light intensity and color. It is super easy to use when you use the app and the timer feature is great. The light fits perfectly on top of a 29gal and the functionality goes beyond expectations.

Really pleased with the quality of light generated by the LEDs. It shines light into every corner of our 55 gallon tank. And the programability is a nice bonus.

This is my second purchase of the light and the first one lasted five years. The product was shipped in the original box without an outside box and it arrived with the end of the box loosely closed and it appeared that the box had been unpacked previously. The light seems to be in good working order at this time. The box was also slightly bent in the middle. The product seems to be unharmed.

My aquarium had algae overgrowth because of my old light putting out the wrong wavelengths and became reset after a power outage. This light was in its original box when it was shipped, not real happy about that part. The box was badly damaged and I had really hoped that the light wasn't damaged. So far it doesn't seem to be. And I absolutely love it. Not only it's easy because there's an app that is very easy to use and set up, although I am messing with the advanced features and that's user error on figuring that out. I don't like the lightning setting in theory it's a cute idea but in reality it just looks like it's going to shock my fish. I have a 55 gallon and I am able to finally get grass on the bottom and everything is flourishing. On top of that my algae is not continuing to grow! It gives a very nice beautiful light! It's really sleek and about half the width of my last one. It just looks so good on the tank and in the tank.

Best lights for the techies out there!Out of all the light systems I've tried, these are probably the most convenient and configurable of them all. I recently purchased a Fluval Flux tank. After playing seeing all the things you can do with the included light system, I made the plunge and replaced all five of my aquarium lights with Fluval lights.Pro's:*Easy/Highly configurable. You can set your lights and color any way you like or use the built-in presets.*Super bright! I've had to tweak my lights often to avoid algae growth, but my plants are going crazy.*The warranty is three years on their lights!Cons's:*The iPhone app is slightly quirky and could use some work. It's just not as polished as other smart lighting apps out there. I find certain features like export custom settings confusing. Not to mention you can only export to lights of the same type. If you have Grown Lights and Aquasky lights, you cannot import-export profiles across light types even if you want a similar effect on both.*I have an iPhone and Ipad. The lights seem to work best when you only use one device to configure them. I've had issues, particularly when I rename a light, the second device will lose connection with it, and you have to re-add the light back to the device.*You cannot group lights or configure similar lights together. I have two lights in my Fluval Flex tank. I have configured each one separately. It would be nice to group them and control them both at the same time. The app treats each light individually.*You only the ability to create one routine per light. It would be nice if you could configure different patterns per day of the week. For example, I have a tank in my bedroom and have the lights come on at 6:30 am on weekdays. I sleep in on the weekends and would prefer the lights to come on around 8 am. I've installed separate smart plugs (Kasa), that turn on the power to the units at 8 am on the weekends.*No integration with Alexa or other Smart light systems. My entire house runs on Smarthings; it would be awesome to update the app to integrate with 3rd party applications. I have two tanks in my living room; it would be awesome if I could tell Alexa to turn off the lights when I want to watch a movie. Depending on the Fluval model, I have to pull out the app or hit the button light itself.*Occasionally, the lights will ignore the routines. I've run into a few instances where the lights should be off based on my configuraiton, but are still on. When I open the app and connect to the light, it suddenly re-syncs and continues where the routine should be.I realize I have lots of Cons, but they are mostly issues with the app itself. Fluval has the basics right but could enhance the app a bit. The light units themselves are great, and the ability to program them on a smart app makes them best in class for the average hobbyist.

When I opened the packaging I was impressed by the overall look of the light, it is very slim and looks really nice. After installing the light and downloading the application software on Phone, blue tooth pairing was very easy. I did get a pop-up indicating that their was a firmware update available, downloaded & installed with no problems.The light is very easy to use and extremely flexible, it has three modes that are controlled from the phone applications, manual, automatic and pro. Manual Mode (picture No. 3) on/off functions, color settings and effects all manually selected. Automatic Mode (picture no. 4) is a preset automatic 24 hour cycle of the colors and level of colors. Pro Mode (picture no. 6) allows six time point settings, each time point setting has 4 colors with a slider bar to increase/decrease the percentage of the colors light. The time point settings and color percentages are easy to adjust and save, it also has a 24 hour preview feature that cycles your settings. the preview cycle only takes 24 seconds so you can see how the light will functions based on your settings.Previously I have been purchasing the $50 China cheapies for my aquariums which were only lasting 12 to 18 months and did not perform as stated in their specifications. The Fluval Aquasky LED Light completely fills my 55 Gallon Aquarium with light, comes with a three year warranty, IP67 Certified Water Proof and is U.L. Certified.I highly recommend the Fluval Aquasky LED Aquarium Light
