  • Great light, 24h cycle is awesome!
Size: 30"- 36"
**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 lost On 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. ... show more

  • Nearly perfect for me
Size: 24"- 30"
hygger HG-978 Operating Instructions ("translated") I love this product. I got a smaller version for my 10G tank a year ago, and used that on my 20G"tall" tank as well. This larger one does more, and that's great! You have options. The bad news is, the instructions are somewhat difficult to understand. Like many things made in different parts of the world, sometimes the English instructions need some study to figure out what they really mean. It happens, and doesn't make it any less of a great product, IMO. So, after some study and experimentation, I was able to condense the basics of this light. There are three ways to use it. The first is to simply turn it on, select a color (it has a bunch), set the intensity level, and turn it off when you want to. Basically a "manual" light. One feature here... you can select a "Color Changing Loop" when you pick a color, and it will cycle through all the colors like one of those old Christmas tree back lights , if you remember those... Anyway... The second way to use it is to set a Timer. This light has a 6, 10, or 12 hour Timer setting. It will be "ON" for the selected amount of time from the time you set the Timer. There will be a 15-minute ramp up and ramp down in intensity at the beginning and end of the time selected. So, you select the color, the intensity, and the amount of "ON" time you want, starting NOW, and there it is. Using the light this way, I'd use a 12-hour cycle @ 75% intensity and shutting down about an hour or two after sunset, so I'd have to set the timer around 9AM this time of year to do that, and fiddle with it a few times a year to account for day length. Finally, there is a 24/7 preprogrammed setting. You have no control over the color or intensity or anything else other than figuring out the instructions! The instructions have to do with time. With this automatic setting, the goal is to have it finish at 22:30 or 10:30PM, according to the manual. Now, you only need to do this once... but what you need to do is look at the clock on the wall NOW, and select the starting point either closest to what your local time is right now, or one to "fool" the system into finishing earlier or later than 10:30. The time selections are 0800, 1000, 1200, 1500(3PM), 1800(6PM), and 2200(10PM). The idea is that if you are setting this light up and it's around noon, select the 1200 setting and it will now cycle without any further input. Off and into the night light at 10:30, and beginning the dawn routine at 8AM. That's it! I set mine at 0700 and selected the 8AM setting. The lights are running in night mode at 9:30PM rather than 10:30PM. So, you can offset or "fool" the system to shift the cycle around the clock a bit. A couple of things about this setting... It seems to never get brighter when you first set it up. VERY SLOW ramp-up and down. It actually takes an hour or so to ramp up to 100% intensity. Nice, really... but I thought it wasn't doing anything at first. And the same to ramp down. The only issue I may have with this setting is if I get too much green algae. That's my sign in my planted aquarium that there's too much light. There's no control on this setting other than time-shifting. I'd like to be able to set an upper limit on intensity. So, depending on my needs for the plants and balancing the algae issue, I may end up using the timer versus the 24/7 setting. That jury is still out. Excellent product! Now, if only someone made one exactly like this one only with a USB port and completely programmable! ::hint! hint!:: *********** After a week or so of using this light, I've settled on the timer function as my default. I set the timer to start at 9AM and go to 9PM. Because I am always up long before 9AM, the timer mode allows me to turn on the light earlier without disturbing the OFF time of 9PM. Also, before 9PM, I can step down the light so that when I turn it on at 7AM or whatever, it's pretty dim, and then I can go from there until feeding time an hour after lights on. More manual, but I'm a control freak, which I think you have to be a bit to keep fishy friends. ... show more

  • Great quality.
Size: 48"- 54"
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. ... show more

  • Pretty good affordable light
Size: 30"- 36"
I like this light. It has warm white light, blue light or red light options. It has a "daylight cycle" which I've used when away from home for multiple days, although that cycle seems to allow the light to be on for a long time for a 24 hr period. It also has a timer option which is where my main criticism lies. There are three timer options: 6hr, 10hr, 12hr. Most people with a planted tank will tell you that 8 hours is ideal to prevent excessive algae growth. So why isnt there an 8 hour timer option?? I end up having to use the 6hr option and then turn it on again for two hours and then remember to turn it off. It's a nice light and the plants seem to like it but the no 8hr option on the timer is annoying. ... show more
