hyggerAdvanced LED Aquarium Light with Timer, 24/7 Lighting Cycle & DIY Mode, Full Spectrum Fish Tank Light for 12-17 in Freshwater Planted Tank

I am very happy with this light. The amount of light and features with this light at an affordable price has made this my new favorite. It is a very bright light with a simple 4 button control. Preprogrammed with different light color options, a 24/7 daylight option (which I love), light intensity control, and a basic timer that does 4,10 or 12 hrs of light. For the price that is a great amount of light options. I love the low profile it has on the tank almost like it's not even there. The written directions were hard for me to follow when it came to setting the timer options (in all fairness that could just be me), but with a quick Google search I found a video and setting is actually quite easy. It is sturdy and well built. I will be buying this light again because there is no such thing as to many tanks.

Have been using this product for quite some time now. It sit atop a 65 gallon rectangle aquarium. The light shines beautifully through from top to bottom adding plenty of light for all your aquarium decor and fish. The 24 hour light setting is a perfect added touch. Emulating the daily light cycle in life. If for any reason it becomes unplugged or you lose power, simply set the timer to the nearest hour indicator to get back on track. It will cycle through orange, white, blue and over night eventually turn completely off until “sunrise” for the next morning. Good quality, great value for money, functionality, and fits the tank perfectly.

**Update 3: Putting this at the top - I'm at a little over 2 years with my 3 lights and they are all going strong. I love them, my plants grow great, and all my aquariums are doing great. These will be my go-to lights for any future builds.**I'm just getting my setup together, but I've been playing with this light for the last 2 days. I'll update this review with any issues once I get my tank setup and planted.The good:-Bright full spectrum light-Super slim-Lightweight-Stays VERY cool to the touch-24h mode is great, and unlike what I've read about the timer on some other Hygger products it does turn fully off. (I haven't tried the 6/10/12 hour timers yet as I don't plan on using them)The bad:-Directions are pretty confusing, especially when it comes to how the 24hr timers work-I don't love the slide-out legs for mounting, but they do the job-RGB Modes are neat, but probably useless to most-No memory if power is lostOn the 24h mode. You can kind of see how it works in the video for the product, but here are some details/info.-The daylight cycle takes approximately 16.5 hours from start to finish.-Day light starts at a dim orange and slowly works up to full bright for the late morning through afternoonish, then starts winding down.-The last ~30mins are blue only LEDs that slowly fade out to off.The 24h button is probably the most confusing part of the directions. It has 8:00 / 10:00 / 12:00 / 15:00 / 18:00 / 22:00 settings. This is for setting where in the light cycle the current time of day is. As an example if I power up the light and want to start the 24h cycle, and its 10:00am I set it to the 10:00 button. If it was 3:00pm I would set it to 15:00, etc. Now the cycle will start at 6am and end at 22:30 (10:30pm). There is a little time math involved if you want to set a different start time, say 7:00 am instead of 6:00am. But this time schedule is perfect for my use.Overall I am very excited to get my setup complete and see how it looks with this light.**UPDATE** This light continues to be awesome! I've had it running for about 3 weeks and my plants are taking off! The "sunrise" is beautiful as well. My one and only complaint so far is that the plastic that covers the LEDs isn't secured in any way and will rattle occasionally from my wavemakers/filter. Should be an easy fix tho.**UPDATE 2** I'm rapidly approaching a year with this light and now have 3 sizes running on 3 different tanks. (10g, 29g tall, 40g breeder) All are working great still. The total light time is a little high (16.5 hours) but none of my tanks are out of control with algea growth. All of my plants are doing great! I'm planning a couple more aquariums this winter and will definitely buy this light for them.

The light I replaced was an older Hygger light. It worked ok, wasn't full spectrum but enough to grow low tech plants. It had a manual dimmer and brightness function. I had to babysit this through the day. I then saw this newer version, but kept using my older one. Flash forward to a month or so ago. I got tired of manually operating my light, so I upgraded. I am so glad I did.I only use the 24/7 function on this light because it's great and does what I need it to do. The set color combinations are excellent and it shows off the colors in my tank and my livestock. Towards the late night hours when the lights become predominantly blue, my night owls come out and I can actually enjoy seeing them in action. Best of all, it shuts itself off and then back on in the morning! I have to say with this upgraded light compared to the older model, my plants are growing bigger, healthier and look happier.Now for the lower cost of this light compared to others, there are some caveats... the 24/7 light feature is set as is. You can't change the time length, light intensity or colors. It's set in stone. You have to live with it. The only thing you can adjust, and through trickery, is the on and off time. The attached controller has set times on how to do this. So for example, if you want to set the light to stay on an hour later, the controller has 8 am, I would hit the 8 am setting at my current 9 am. If you want the light to go off an hour earlier, than you would set it an hour earlier than what the controller says. This however will still offset the ON time +/- whatever time you choose. Also the instructions and this listing says the set stock time of lights off is 22:30 but in actuality, the light does not turn off for another 20 minutes. 22:30 sets it to the final stage before shut off. The controller unfortunately does not have memory. If you experience power failure or cut power to the light, then you have to manually set your light timing again.. it's a little of a pain trying to remember the instructions or having to wait for the proper offset time (if needed).The legs on this unit.. you only get the short option. I really wanted my light higher from the top of my tank. The old Hygger had the option of 2 different set of legs. One was a little bit higher. I had to rig something up to do that, but it's still not really where I wanted it to be.Even with those caveats, the 24/7 feature works great for me, but I can see it not working for everyone. Especially if you don't have a planted tank. The length of lighting might be too much and might be an issue for me if I didn't have floating plants to block/absorb some of the light. However currently, this automated light has made my life much easier and gives me more enjoyment from my tank looking at all the vibrant colors.
