NICREW SkyLED Plus Aquarium Plant Light, Freshwater Fish Tank Light with Ramp Up and Dim Down, Spectrum Adjustable and Lighting Schedule Programmable with Controller, 30-36 Inches, 30 Watts

I purchased this light because this manufacturer has earned a good reputation with its aquarium lighting. This light in particular is one of the brightest I've found for this price ($47). The 30-36in light fits perfectly on a 20 gallon long tank. You dont need this light if you dont have a planted aquarium. which are less bright.Im super happy with the color spectrum & strength, ive noticed the plants have noticeable growth after 1 wk. The timer works as it should.Worth noting is the initial set up. Many reviews mentioned the complexity of setting up the built in timer. I ignored the reviews, thinking "how bad could it be?". Well, let's just say you won't be able to get by without reading the directions.The light comes set for 100% strength from 9 to 5, but you can adjust the duration as well as the intensity. Youll need the directions because theres a button that youd think means "back" but its actually "undo" so if you hit that, all the settings you've just inputted will be erased.Because of all the adjustability, initial set up is a little excessive, but thats the cost of having said adjustability. Once you've set it, which im embarrassed to admit took 10 minutes, you dont have to mess with it again. This light doesn't have a remote or pre-set modes, such as cloudy, moonlight, thunderstorm, etc.Great light for anyone seeking a straightforward light on a timer, for planted aquariums.

So I just got it, I cant attest to the durability of it yet. However, it is an amazing light so far. It can get really bright and has great lows. The daylight setting makes it very hands off. I would recommend this light for freshwater aquariums.The programming of the timer is not intuitive but you'll get it. Its as simple as setting on top of your aquarium so the installation is really easy. As for build quality, its very durable and has all the functionality that I need.

I really love this light! I have a new 40-gallon aquarium and when I started looking for a light I was reminded that I had purchased this brand in the past and recalled how much I liked it. But this one has a great feature that the last one I bought did not have - the programmable digital device that takes the worry out of lighting my tank. The device allows me to preset on and off as well as brightness and type of light. I love that it is LED which provides optimal lighting for my fish as well as the living plants while reducing electricity requirements. This light is awesome.

I installed this light on our 40 gallon bow-front aquarium and it looks great. These tanks are tall and they need a strong light. The light is strong enough to make the whole tank shine. The programming works well also, although you need to read the instructions to know how to set it. The cables are long enough for my setup, but not too long. (Don't make the shorter, I needed them at full length.) Things I like:* Color balance and ability to adjust blue separately* Light strength (more than enough for my planted freshwater tank)* Night time slow sunset and moonlight programs.* Packaging and assembly is robust* Controller display is easy to readThings that could be improved (took off 1 star):* Memory when the power goes out - it should keep time for at least a few hours* Retain programming when power goes out - I know I'll need to program it all again when the next snowstorm kills the power on us* Dimming is linear, not logarithmic. People observe luminance on a logarithmic scale. The dimming adjustment should be exponential so that 50% level looks 50% as bright as 100%. I adjusted the white from 100 -75 and could not even see any change.Otherwise this is a solid product. I'm sure they will solve the time retention problem soon. (All my little timer modules for my other devices remember the time when the power glitches. ) It's a nice product and I am happy I purchased it!

So far I'm loving these SkyLED lights. I own two of them. I also own 3 of the Classic Gen 2 lights and like everything about them except the timer. With them you have to be home at the time you want the lights to come on in order to set the timer after a power outage. These SkyLED lights are brighter, more water resistant, and have a much better timer, with more options, and so far, has remembered the settings after a power outage.
