hygger Auto On Off 30-36 Inch LED Aquarium Light Extendable Dimable 7 Colors Full Spectrum Light Fixture for Freshwater Planted Tank Build in Timer Sunrise Sunset

So after using this for a while, it has been a real solid light, works well, super bright, easy to program the clock and the timers after you look at the instruction video. I love that it is adjustable in 10% increments on all of the different light settings. Only thing I noticed...it forgets everything if the power goes out and you have to program everything again. My other light has the ability to save everything when the power goes down. Other than that this is a really great light, I would buy this again if I get a second tank.

This is a good light, but now there is even a better light in the market called the Brite which is bluetooth activated with UV light and easier to customize for your planted aquarium. This light is pretty easy to program, I’m not sure why I see so many reviews complaining that this is a difficult light to program…. Took me like 5 minutes to set up for a Siesta Planted Aquarium for my 29 gallon and 5 gallon planted tank. Plant growth has been crazy with the Siesta Method. Currently I’m using a Siesta Method with this light with the current setting: To set this light for custom mode. You first need to turn off all your other mode first or it is not going to work! Then you simultaneously press the setting and light bulb button at the same time. Remember need to set it to ON then press the setting button again, and you will start with L1 with the flashing number on the right. The number on the right indicates the intensity. Press up and down to control the intensity. Once you are satisfied with the intensity, press the setting button. The left side time flashing is the time your light will be on. The right time flashing is the time your light will be turn off. Press setting to confirm your time and it will switch to L2, repeat your step. Literally L1 - L8 is like a timeslot that you can customize…. How can people not understand that?…. L1 - L6 is full spectrum and L7-L8 is night spectrum. Always have 0% on L8 if you dont want algae. If you want algae and have your night mode on the whole night then go ahead. Light 8am - 12pm on. 12 - 4pm off. 4 - 10pm on. This would allow for a 4-4-6 siesta planted aquarium. L1: 8 - 9: 50% L2: 9 - 12: 100% L3: 12-4pm: 0% L4: 4-5pm: 50% L5: 5-9pm: 100% L6: 9pm - 10:30pm: 10% L7: 10:30 - 10:31pm: 0% To turn off the night light L8: 10:31pm - 7:59am: 0% To turn off for the night and reset back to L1 time This siesta light setting is perfect to view your aquarium and let your tank Co2 reset. This also reduce algae. This siesta method also work if you have a Co2 tank, you can also use this setting for your solenoid Co2 7-11am on 3-9:00pm on

I was looking for a light with the 24/7 mode so I don't have to worry about turning my lights on and off manually and forgetting to turn them off at the end of the day. I also needed a light with the blue light for my daughter's glofish tank but I didn't want it I be blue all day as I needed the regular light to keep the live plants happy. This was the only light that would check all those boxes. It turns on in the morning based on what time you set it at and then at 6:30pm it switches to moonlight mode (blue light) which is great for the glofish to pop and then it turns is m itself off at 11:30 or what ever time you set it to turn off at. The whole point of 24/7 mode is to be able to set it and forget it but being a glofish tank I wanted to have the blue light in the evening and into my daughter's bedtime. I only have 2 issues with this light that I don't like and reason for my 4 star rating. 1. It's almost too bright without the ability to turn it down in 24/7 mode. I have the 24 watt one for a 10 gallon but wow at 100% it's really way too bright and has caused major algae issues that I've finally gotten a handle on. 2. The controls are absolutely awful! I really wish this came with a remote like my nicrew but instead they are on the unit itself which is not good. For example to switch from manual to 24/7 there isn't a simple button for that. Instead you have to push to buttons simultaneously and hold them for a couple secs, then push on or off and then push the light button. It's not user friendly what so ever. Overall I really do like this light and the fact that it goes from normal light to blue light all within the 24/7 mode is the only reason I bought it and continue to use it. If you don't have glofish along with live plants I would advise getting a different light like the nicrews which are amazing in my opinion and about the same price.

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.

Excelente lámpara rgb, es una muy buena opción

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.

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.

Sus funciones de simulación del Sol y luna me gustaron mucho, pues no se prende ni se apaga de golpe, si no que va incrementando y reduciendo su intensidad lumínica en una pre programación de fábrica, y solo ajuste a mi hirió preferido y está funcionando hizo lo suyo automáticamente. La recomiendo mucho, yo me he dedicado a fabricar peceras de acrílico y dar mantenimiento, y está lámpara supero mis esoectativas dado su precio, pero hay que considerar que no la recomendaría para corales vivos en peceras marinas, pero si para plantas en acuario de agua dulce. Valió la pena la compra y solo espero que dure lo suficiente 😃👍
