AQQA Aquarium Light,Full Spectrum LED Fish Tank Lights,12"-54" Adjustable Multi-Color White Blue Red Green LEDs with Extendable Brackets,14W-31W for Freshwater Plants (14W (12"-18"))

So dumb of a design that it doesn't matter how good the lighting is. Every time you turn these off, and back on, they change settings. So you can't get consistent lighting with a normal light timer, which for me makes them ridiculous and useless! Edit (hold on, there is a fix)The other downside is the voltage transformer is built into the control switch. So WHEN the transformer goes bad (and they all do in time) you can't just replace and or upgrade the transformer. Also the controller/transformer gets hotter than most, and in my experience with hundreds of LED lights it makes me question it's durability and it's ability to last. but the price is so good...The ProsThe Color rendition is great! Better than a lot of very expensive lights. 2 out of the 3 setting are VERY VERY GOOD. The best of any budget Aquarium LED I've ever seen. (personally I think the green LED's don't help much and they seem to wash out some of the more eye pleasing colors. I will block the greens in some tanks with some electrical tape on the outer lens cover)Lighting intensity is also very good. I'm sure like most cheap LED's these will dim some with time because the fixture gets hot and heat tends to be hard on LED's. These find of things to be expected with cheaper lighting so not a big deal.Conclusion If they remembered the last setting I would have giving them 5 stars for the price. Edit; I change the rating to 5 stars because the fix.THE FIX!For not remembering sittings.Get a advance digital timer. (I use the BN-LINK 7 Day Heavy Duty Digital Programmable Timer)Sync the light setting. It will requires some math. The right timer can be programed to cycle on your lights 3 times within three minutes. So that way, you get the same lighting every day. You can also cycle for desired different lighting throughout the day.So with the right timer it makes it a 5 STAR low price lighting system.

I bought 2 of these 36 inch lights to go over my 6 foot, 125 gallon aquarium. They are a great value. They are bright. Unfortunately, just outside the return window, 1 works well still and the other light started flickering, but settling to be on for a few weeks. Now it does not work in the full spectrum settings, only the white light setting. I have been using these since mid January, 2022. The one light started being faulty in April 2022. They also seem to be fussy about which of the 3 settings they are on. I can't really find a consistent pattern to get them to cycle through the settings, even on the light that does work. *EDIT AQQA replaced my intermittent light with no questions asked. Very prompt and courteous service.

The light is perfect for beginners for start up salt tanks. I like the different light modes but it doesn’t have the built in black light for coral. As this light will do for now, I know I will be purchasing a little pricier light once my tank becomes fully established. I have a 60 gallon with the length of 48” and let me just say yes the light reaches but barely. I almost considered removing the legs and resting the light on the lid. I do wish the length of the light itself was as longer tho.

I'm extremely happy with this product. I'm using it with a 20 gallon breeder tank. It's adequately bright and the function button is easy to use. The black casing matches my tank trim and looks great. My plants have been growing well since I added the light. The price on this was great too.

This light worked great for about a month, then all the color modes other than the regular white light stopped working. That was fine for me since I only used the white light anyway, but it was a little disappointing.Fast forward 9 months later, the light stopped working all together. Now, LEDs should last years so I figured something happened to the cord or the switch got fried, so I took the cord and switch apart and tested the components with a multi meter, everything worked which meant the issue was in the light itself. When I tried to take apart the light itself (I did like this light while it worked, so I wasn't ready to give up on it yet), I discovered all of the screws holding the fixture itself together came pre-stripped, so there was no easy way to get it open to examine the diodes themselves.As I mentioned above, LEDs should last years. The fact that this light only made it a few months indicates either a) low-grade materials, b) really poor workmanship, or c) both (most likely from what I saw).I will not be buying this light again and I would not recommend it to anyone.

Worked perfect on my 10 gal aquariumLooks good the collars come out perfect and easy to install

The media could not be loaded. Update!! 7/28/22: Causes algae! Lots of Algae!!First light:The description states the light will accommodate up to a 30 inch long aquarium, has 3 light settings and a timer.The 30 inch light measures at only 22 inches long without the extension bars attached. After putting them both on, it barely fits the tank. The extension bars are thin like a wire hanger and not sturdy enough to hold it level which is why I attached mine above the tank.Brightness is really nice and bright. The first set is all colors: red, blue, green and white. Second is only white and the third is only colors. No single color options.Timer doesn't exist on my light. It should but it doesn't.Second light:Same description as above except it says it accommodates up to a 36 inch long tank.Only measures 30 inches. After extension bars were added it was just like the other one, very flimsy and barely reached 36.All other info is the same as above.FINAL THOUGHTS- Not bad but could've been WAY better. I would not buy these again only because there are other options for a few more dollars and you get what you pay for. I'll update the post if they go kaput!!

Very powerful at a very low price. Should be good for a 5 to10 gallon planted tank
