Hygger Auto On Off 18-24 Inch LED Aquarium Light Extendable Dimable 7 Colors Full Spectrum Light Fixture for Freshwater Planted Tank Build in Timer Sunrise Sunset

Only problem is that the user manual is too concise to understand the settings. Otherwise this is the best light I ever used in my 20 + years of this hobby.

Firstly, the delivery is great! It came earlier than expected. The product's build is good. The complaints by reviewers about the control panel being sensitive to touch is real. Just have to learn to get to use to it. Overall, it is a good product from my unboxing it and trying out the modes and settings. The standard mode should be adequate. Just ensure the time settings of Day-ON and Day-OFF that work for you.

Been using this light for about 2 months. Very bright and I actually only use it at 50% as I have no plants to grow. In the automated setting you can not dim the light and I found it over powering. I "DIY" mode though you can set the intensities of each stage of the timings. There are 8 total diy setting modes you can program in that let you set on/off times with intensities. 1 through 6 give a nice clear white light, 7 and 8 give you blue. All 8 modes can be run dimmer mode. During power outage it will remember your settings but you will need to re set tge time. A bit of a pain but also eliminates need for a battery backup in the light. As long as I have no issues in future I am extremely happy with it. From my understanding the manufacturer is also very good at making issues right which is some peace if mind as well. I bought the 48 to 55 inch verson and at that price you are actually getting a very good light at a very reasonable price compared to other options. It may be a little more expensive than the real bargain brands but the programming function alone makes it well worth it. I've bought a second one now for another aquarium.

Excellent Aquarium lights! I use these for my vivariums & they work spectacularly. I did a lot of research before buying these lights & the hygger brand was highly recommended & I can see why. They have many customization options, & my favorite is the DIY cycle so you can set brightness/color/time for the entire day. The only gripe I have (which is a common gripe I read online) is that the instructions are confusing & it can be hard to set up until you figure out what to do. But once I knew how to operate the lights they have been great & my plants are thriving. I definitely recommend these lights for an aquarium/vivarium setup.

I have two now and I’m probably going to get more for my other tanks as well! I also just bought the clips for them so that’ll be even cooler. I like the timer aspect and the screen. I’ve dropped it in water and still works perfectly. I feel the settings are fairly simple and straight forward. Overall great light lights my tank well and grows my plants too! I can’t wait to get more.

First professional light i have purchased outside of the light that came with the aquarium. Once installed and configured the light output into the tank was amazing. Even the wife was impressed. lol. The outside casing gets a bit hot to the touch. The color and on and off timer settings, remain after short power outage but are easy to reset up if need be.
