Aquarium Light - 95 Watt Sunrise Sunset Moonlight, Group Control Program Coral Reef Light Dimmable Full Spectrum for Marine Tanks,Saltwater Tank Light with Timer (Brackets)

I have a 125-gallon saltwater mixed reef tank, and these lights have been a great addition. They're bright, easy to set up, and the included remote control makes adjustments super convenient. I’ve customized the timer and lighting settings to suit my tank’s needs, and I’m very happy with the results so far.The PAR output is strong, so it's important to fine-tune the settings based on your specific coral and livestock requirements. I’ll be purchasing two more units to ensure full coverage across my 6-foot tank.

This light is well designed and well made for the price! If you just want something with controls to set and forget this may be the light for you but there are a few cons too.Pros:- excellent spectrum and color mixing, colors in my corals and fish look as good as expensive brand lights, and actually better than a lot I've seen- there are six channels and they are a little different that the description, and are actually ideal: 1 - cool white, 2- blue / royal blue, 3 - even deeper blues, 4 -violet/UV, 5 - warm white, 6 - green- time and programming is kept when the power is disconnected- the menu and touch controls are very simple and easy to use, unlike some other Chinese black box fixtures (and some of the high end brands too) this one seems like a lot of thought went into the design- dimmer mode which lets you override the current daylight/night timer setting and will keep the color setting in memory so you can quickly go back to it any time, or have it turn on in this mode from an external timer- night mode which turns off all but the regular blue channel 2- if your whites/green are set lower than blues, during sunset and sunrise the tank will be all blue for a few minutes, I personally like this for some may be a con- because all of the LEDs are close together and under the same lens the colors blend well and disco affect is very minimal or not even visible at all depending on settings- well designed open heat sink for very effective cooling and a quiet fan whose speed goes up with temperature. The fan doesn't even come on on my settings and runs at 30C (the menu shows temperature)- the optic is excellent and it has a good even spread at the appropriate angle, I don't get too much spill outside of my tank- plenty of cord and the cord disconnects about 3 feet from the light making it easy to remove if you need to- stand is decent and allows two axis movementCons:- when powered on it flashes all of the colors on high one at a time for a couple seconds, no matter what mode it's in when it's turned off- as the light level changes for sunset and sunrise the color mix changes slightly. This is because you can set each color to 0 - 100% in 1% increments, but the dimming for sunset/sunrise is only in these same 1% increments and not finer, so as it changes some colors will go down a percent or go to zero while the other's are unchanged during that step. Of course this will all depend on how your colors are set and the length of the period, the bigger the difference between the channels the greater the effect (mine are at 5% whites/green 30% blues/violet and the effect is very noticeable)- It's not water proof, there are no seals at all. If water is splashed it will get in and could get on the circuit board. They attempted to apply a conformal sealing on the circuit board but they were very sloppy and less than half of board was coated. DO NOT MOUNT WHERE IT WILL GET SPLASHED IT WILL GET RUINED QUICKLY- there's a small flashing light on the outside that flashes continuously ever 2 seconds. There's an option to turn it on in the menu but it doesn't work

I have been using these for 2 years. Both LPS and SPS grow well under this light. This product is well made. It has a good form factor, great configurability, and an affordable price. I also have the G3 version of this light for my other smaller tank. It offers similar excellent qualities at a smaller size. Both G5 and G3 are great reef lights, especially for reefers who are price conscious. Highly recommended.

I've been running a Nicrew 100w on my 20g (I converted to an AIO) for about 1 1/2 years. I needed about 25" of coverage, not the full 30" as I used 5" on one side for my overflow and return chambers. Depth isn't a concern. Although I really like the Nicrew's spectrum with respect to coral color pop and being able to control the whites and blues independently (meaning a separate ramp up/down for each using the optional $50 controller), I didn't feel like I was getting the right coverage and my corals didn't seem to be doing well. I ended up supplementing with a 24" 2 bulb T5 which did seem to help quite a bit. I also added separate moonlights with one of those 14" flexible wands. So 3 lights for a 20g - seemed like overkill. So, I was torn between replacing it with the 150w Nicrew (which should provide the coverage I needed) or the SmatFarm.I saw a couple of tanks with lights like these on it and really wanted to give one a try, so I pulled the trigger on this one and just replaced my setup the other day. So far, I'm really happy with the decision. There are a few improvements that could be made that would give it 5 stars across the board for me.Pros:1) Shimmer. This is something I've always wanted on my reef tank, but was never willing to pay the high price of the Kessil or hang a MH light over the tank. The Nicrew didn't have a shimmer but this one does and it looks amazing.2) Spread. This has a much larger spread at the same height, but the mounting arm allows me to go even higher than the Nicrew. I have it maxed on height, which I probably don't need, so I may lower it just a bit.3) Controls. The menu does take a little to get used to, but after fiddling with it I really like it. You basically have ways to control the sunrise (how long), sunset (how long), moonlights (how long), and then you program the sunlight and moonlight spectrum color mix and intensity settings and it ramps up and down for you. It also comes with a remote but I haven't really used it yet - not sure if it's useful or not. The screen is super-clear high definition (OLED), but the buttons are very sensitive. It also has a very cool and useful 'test' feature of your program in fast motion so you can see what your entire schedule will look like in about a minute's time.4) Spectrum control. You can control 6 spectrums independently - 2 different blues, purple, green, cool white and warm white. Surprirsed there isn't a red option vs the green.5) Quiet. I don't even hear this thing running.6) Size factor. It's very compact and easy to work with, and solid.Cons:1) Mounting. It would be nice if it allowed you to bring the light a bit further backwards - meaning closer to the arm. For my 20g it sits a couple of inches closer to the front of the tank than I would like. You could, if you really wanted to, just use one screw and bring it back more, but it would angle forward which I don't want. Allowing it to move further back would also help with the counter-balancing of the weight. This is one feature that the Nicrew is better - the weight seems to be more vertical ON the glass, vs AGAINST the glass, so less stress. I used a piece of black acrylic on both sides to spread out the pressure ont the glass. I HAD to use the one on the inside (slightly lowered) to keep water from squeezing up between the glass and the mount, over the back rim. Not sure how, but it was doing it. Adding a piece of black acryllic on the inside, slightly lower than the top of the mount, fixed this problem.2) Ramp up down is limited if you like all blues. I've always run my tanks with just blues in the morning and in the evening. Even when I had just T5s, I put sets of bulbs on different timers. Unfortunately the sunrise/sunset really don't allow you to control it like this. But, I figured out a creative solution that I'm happy with. I set my sunset from 7pm to 7:01p and set my moonlight to 7p to 9p - with the blues set to 60% to match my max blue intensity for sunlight. This turns off my whites at 7p and allows me to enjoy just blues at a the higher intensity as it ramps down over 2 hours. I don't like moonlights that light up the whole tank, which is what these blues do even at 1%. I like the pinpoint almost lazer-like spot of blues shooting down into the tank, which is why I had a separate moonlight and did end up adding that to this setup as well. That freed up the moon feature for me to enjoy just blues at a high intensitiy without the whites. The problem with the sunset is even if you have your whites set to 1% and your blues high, the ramp down keeps the whites on as it ramps down and it's just TOO much white and doesn't look good.3) Whites. The whites are way too much. Even at 1%, you have to have the blues up to 50-60% or so before you really notice the blue. Seems like a lot of lights are like this. I like some white, but right now I only have them maxing at about 3% right now. I might increase this up to a few % points as time goes on as I'm ok with more white during the day.Overall, the cons are not enough to spoil the pros. If my coral responds well to the light over time (so far they have already adjusted really well/quickly, and the light lasts, I'll be extremely happy with my decision. I'll come back and update after I've had it for a few months.
