hygger 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.

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.

Overall I’d definitely recommend this light. My tank has an outer width of exactly 30” and the light fits perfectly. I bought the 30-36” model so the light covers all of the tank. In the photo the light is at 60% power, which has been a good balance of brightness while not giving off heat (light is just barely warm) or causing too much algae growth. I have it on a UPS so even if I lose power the timer doesn’t reset. Worth the extra $50. My only gripe is the programming. The default mode has a smooth transition between brightness levels, but you can’t pick a max brightness. 100% brightness is way too bright during the day and I don’t want the blue light to be on at 100% brightness all night either! If there was an option to set max brightness in the default mode that would be an easy 5 stars. The manual programming is also not my favorite. 8 options is nice, but you can really only set time and the last 2 slots are locked to the blue color. That means despite the light being programmable you can never program it to use the red, green, purple or teal light! That’s silly to me. Also, programming using 12hrs seemed very buggy to me so I switched the time to 24hr and haven’t had a problem since.

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

The sunrise sunset function has a glitch that turns the lights off before the set time. The DIY mode does not work at all. I went through the programing as shown and everything looks fine until you finalize the last off time and the light goes to some very dim setting and the Day-L (ON) keeps flashing, so clearly a glitch in DIY mode as well. Manual mode work fine. This light would be great and I would give a 5 star if the functions I purchased this light for worked. I purchased 2 of these lights of two different sizes and they both do the exact same thing. Look through the reviews, I'm not the only one.

I've had aquariums off and on for about 40 years and this is the absolute best light I've found. No more worries about too much light or not enough light. I'm trying to go all natural in this tank and found these lights perfect. They have a great moonlight setting! After 6 hours of that it goes completely black. The light has a great warmup and cool down feature where the light gradually either comes on or goes moonlight which is the blue. Sorry for the reflection of the light and window in the pictures but I wanted to get a view of the colors. Overall great product!

So this product gets 2 stars because the light itself is bright and nice. But the rest is horrible. The panel is not intuitive, but you can find a tutorial to help you walk through the config. If you unplug it, it wipes the config and you have to do it again. If you turn the light on before the programmed start time, it will NOT turn off at the programmed off time. Learned that the hard way. Sometimes the panel buttons just don't work, so you have to unplug it and plug it back in to get them to work. Sometimes you dim the light, but the light does not actually dim. You again have to unplug it and plug it back in to get it to work. I highly suggest avoiding this light and getting something similar with no programming using an outlet timer.

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.

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.

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.

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

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.
