Aquarium Programmable LED Light, for 30~36in Long Full Spectrum Plant Fish Tank Light with LCD Setting Display, 7 Colors, Sunrise Sunset Moon and DIY Mode, for Novices Advanced Players

I want to give it 4.5 stars but that's not possible so I'll be nice. It's a great, powerful light, but that's all it has going for it. It's too powerful to leave at 100% and flush with the aquarium (how it comes unless you buy risers.) This causes algae in new tanks. You can only adjust lighting % temporality without going into custom mode. Their sunrise and sunset feature is horrible. Once again, it can't be changed without going into custom mode. It uses an hour and a half for both sunrise and sunset, slowly ramping up and down the lighting. This means if you set your light for 8 hours, you really only get 5 at max intensity. If you want 8 hours of light, you have to set the preset for 11 hours because of this. It's absolutely horrible in this way. If you don't want your light on for 11hours a day and causing algae issues than you just absolutely have to use custom mode. The custom mode is just annoying to deal with but it's the fact that it could just be SO much easier. Simply being asked if you want to use sunrise/sunset mode and being about to adjust the light intensity and have it stay there would be a good start. Overall, it's like Hygger got into the high end light business but forgot to we use them to grow plants. Overall, 4.5 out of 5. Maybe closer to a 4 if I wanted to be critical. A good light but the ease of use isn't nearly as good as it could be. Overly complicated to customize with horrible preset lighting settings and timers. All of which could have been avoided if thought out more.

Just set this up on my 20g long today and I love it! The automated timer feature was really important to me because my work schedule doesn't always allow for me to be home to manually control the light on a consistent schedule. I'm also looking to have a planted tank in the near future which this will come in handy for. One thing to be careful about when first turning this on is that the white light is set to maximum brightness which may frighten your fish if you're coming from a cheaper light that doesn't get very bright. When I first turned it on, it was set to the red light at low intensity, it took a few button presses to get through the other colors (also at low intensity) before I got to the white light and it was SO bright...I felt like I died and was at the pearly gates, and so did my betta, he had a mini freakout lol. I dont think either of us have ever seen the tank that bright. Wasn't a bad thing but definitely a shocker. I had to pull the intensity down from 100 to about 70. Had I known about this before I probably would've turned it on and cycled to the white light before I sat it on the tank. Other than that, I set up the day/night timer within 30 minutes...I was a bit confused about how to work all the buttons and how they controlled all the settings at first so I had to read the manual a few times, but every piece of technology has it's learning curve so not complaining! Excited to see how this works out, so far it's a great investment. My betta and his soon to be tank mates will be very happy!

My show tank, 2x2x5, is using 4 of these, the timer is good as the lights all cycle within seconds of each other. the light is keeping my plants on the bottom (and floating) alive. Because of the 5' length I could not fit long units and get the light I wanted, so I got a size I could put end to end. The Tank was originally for salt water and had dual metal halides, and they ran hot, 6 cooling fans in the hood, one off the ballasts was failing, so on prime day I ordered the 1st pair, using them on the side the ballast was dimming/dieing. With frequent power outages that decimated the marine creatures 3 years in a row, I converted to freshwater. The Fish looked better, the tank ran cooler, the plants lived, and energy usage went way down. That being successful I ordered 2 more (when the size came back in stock). Happy with the results. That said, why 4 stars? Well the 1st pair is awesome, it took a little while to get the feel of the controls and time settings, but once I had it they have been champs. The 2nd set not the same, one has a single green light in the row of blue when in night mode. Neither o the newer ones would do the SOP to reset, and when the cord is disconnected they lose their settings, though without the cord disconnect the remember time over short outages. A little more work, but they do what I want and would buy again (just hoping more like the original set). Last thing, the light is good for freshwater fish and plants, may even suffice for some marine uses, I would not recommend for use with corals unless it was a very shallow tank.

I have a 55 gallon tall tank. The light I had before was not bright enough to grow plants well on the bottom. This one is much, much brighter and should grow my plants better. The downfall of this light comes from the programing. I absolutely love the program, but my son has played with it and my moonlight phase is now green. I am sure I can fix it, but I will need to read the instructions and attempt to correct the issue. The instructions are a handful to read and printed in super small script, which makes it hard to follow. Overall, I love this light and will purchase another in the future for another tank.

Arrived quickly and well-packaged. Performs even better than I hoped. Love it!

I would recommend going with a more known and trusted brand. My first Hygger light lasted for about 15 months, before the light started blinking red, and then wouldn't turn on. I assumed I had gotten water in it somehow, so ordered another one. The 2nd light lasted about 4 months before doing the same. I reached out to Hygger support and got a response asking for a video. I sent a video of the issue and they said it was the power adapter and asked for my address to send a new one. - 2.5 weeks later I've gotten no further responses back from the customer support email thread despite me asking for a status update, and have not gotten a replacement adapter.

The light itself is high-quality, but the programming interface is a nightmare. The manual is vague, and the screen shows confusing flashing indicators that make it feel broken. I spent over an hour fighting with the DIY mode just to set a simple schedule. Now, I’m stuck playing a waiting game to see if my settings actually saved or if it’ll just fail tomorrow. Great hardware, but the built-in timer features are a massive headache to navigate.

This was a very good purchase for me. Love the convenient timer and ease of setup. I also really enjoy the automatic moonlight setting that comes on a bit after total lights out. There are intensity settings which I have at 80% and the plants are still flourishing. Has an attractive low profile and you can switch from 12hr to 24hr mode. It does get a bit warm to the touch so be careful. The connector between the light and the plug is a little sensitive but other than that, so far, great product.

Easy to program, fabulous colours, plants love it. Only concern is the plug and top feels very warm compared to previous model. Not cheap..

Es un buen producto, tengo plantas de bajos requerimientos en un acuario de 0.80 x 0.40 x 0.50(alto) y me ha funcionado muy bien. No es tan intuitivo programarla, revisen videos para que les sea de mayor facilidad. Tengo varios meses con el producto y cumple con lo que ofrece.

Materiales de buena calidad, pero se calienta demasiado y lo peor es que se desprograma el reloj si se va la luz (muy común últimamente) y debo programarla denuevo... Y ni siquiera se puede utilizar con un enchufe inteligente ya que cuando se conecta no se enciende

Para ser honesto es la primera lámpara que tengo de este tipo y de momento me ha funcionado muy bien sin presentar ningún problema en los 4 meses que tengo de adquirirla, solo hay que estar investigando las configuraciones por que de momento pueden ser algo confusas, el único detalle que le veo es que cuando la prendo al 100% de iluminación, se calienta en exceso por que siempre la tengo al 60% ó 50% y mis plantas han presentado mucha mejoría desde que adquirí la lámpara tomando en cuenta que de son de bajos requerimientos.

Esta padre la luz, tiene buena programacion y bastante luz. Sin embargo, comparando eso, con lo que se calienta la luminaria en si, y el cargador, creo que es una falla de seguridad en la casa, puede llegar a ocasionar incendios, cortos y demas. Regrese el articulo y compre otra luminaria de la misma marca, que ha salido buena.
