Aquarium Light –3rd Generation A029 Aquarium LED Light 30 Watts Saltwater Light with Touch Control, 5W LED Chips for Coral Reef Nano Fish Tank Marine Tanks with Timer & Screen (A029)

Great little light. Have it over a frag tank that's 12 in high x 24 in wide x 18 in deep and it lights up most of it. Coral seem happier since installation. Time will tell if it grows corals well. May purchase another if this proves to be under powered for the frag system. Update (4 months since installation): Proven Winner; albeit, this is over a 12 in high x 24 in wide x 18 in deep frag system plumbed into a 150 gal multi-tank system running full power on an analog timer. We grow soft corals and keep a number of LPS species healthy with a low tech setup using a macroalgae refugium, an aging & under-spec protein skimmer, and a massive amount of live rock/water flow with minimal dosing. This little light has some decent PAR values at shallow depths (may be good for low-light corals at ~18 in depth, no promises). Growth of coralline algae spiked and maintained strong growth rates since early February 2018, without other changes to the system. The most drastic change was to our coral frags, anemones, coral rescue cases, and coral mother colonies. We've never used an AquaIllumination, EcoTechMarine or other high-end LED light on our personal systems but we are definitely impressed by the quick healing, rapid growth and reproduction rate exhibited by the corals in our frag system with this light. For example, we purchased 10 small rainbow rose bubble anemones around the same time and now have 23. Our 2-head green duncan coral that was dying from a flameback pygmy angel attack has between 10 and 15 heads. The correct wavelengths of light are present in sufficient quantity to do what it says it will do, grow corals (given it's applied to a tank that's within its capabilities). Please note that the anodizing on the aluminum will rapidly disintegrate (~2 weeks) when continuously exposed to salt water. This is generally expected with hard anoziding v. salt water (possibly slightly electrified), did not exceed the water line, had no negative impact on our system, and quickly grew over with coralline algae. The support is strong and stable if properly secured with some common sense. The photographs attached were taken today, after ~4 months of use. Perfect for a nano, pico, or frag system. I recommend buying this one if it's on your short list; it's worth the extra over comparable budget led fixtures. Dollar for dollar, it's hard to beat this little giant. Just wish it was made in the USA.

This is a very well designed, engineered, produced and finished device. ;0 The light fixture itself reminds one somewhat of a "VCR" cassette. approximately the same width and thickness and height but about two inches linger. The "feel" of the light portion is nice and the finish on the "arm" is rather amazing, it really does feel rather like "skin" when one is handling it, it reminds this person of what is called a "powder" finish. There are multiple screws with turning knobs, two large for the mounting bracket an "cap nuts' again, all well finished. A couple of the cap nuts were missing and the company replaced them quickly, .....arriving on a Sunday! :) Since one will be manipulating it several times during it's lifetime having something pleasurable with which to work is a good thing in terms of repeat orders! :) It has a set of VERY BRIGHT actinic lights and also blue lights of which I cannot opine but they do produce a very nice bright effect in the corals... Quite a "glow". One fish which was acclimated to a "fluorescent" actinic ( which is not as strong ) went and hid under a coral but new ones did just fine with it. I am also using it as a "test" for culturing algae, I teach college biology, and the algae are thriving! :) One of the problems with raising algae in a laboratory / classroom situation is that of it being a multi -use room and I plan to make an "L" frame upon which I will attach this so that the materials can be moved as necessary. The power cord is quite long, 6 feet approximately with a "banana plug" in the middle so that one can get a setting correct on the light itself and not have to turn it on and off when entering and exiting the room. And the reason for that is... The light fixture uses two "touch pad" buttons ( on the top ) with a plus sign and a minus sign, to cycle through pure blue light to the white "actinic" mode. This is a great thing in that it produces a situation rather like " a dimmer" but at no extra cost or extra device which can fail and that, again, in a laboratory / classroom setting a teacher can change the lighting for a particular use and another professor can so do also. The only slight criticism that I might have is that it might be nice to include maybe "two" ( 2 ) red LEDs in the follow on product but that, in and of itself, presents engineering problems and also USER problems in that another button would have to be added for the red LEDs and the USER would have manipulate three buttons. The best fit answer might be...a remote....but again, that presents problems in terms of getting lost, battery acid messing it up and such....so..maybe the best thing is to let an already good thing alone. :) All in all it is VERY well designed, I would recommend it for anyone who needs some kind of design that is not attached to "the underside of a shelf"; and I will be purchasing another for use in the laboratory.

I wanted to love this light, it's so bright and beautiful and makes plants and fish colors pop out so well it makes our old led bar light look dim and ugly in comparison, to top it off the fan is silent and the mount is sturdy and good looking. The touch buttons are just a complete deal breaker for me, they don't always register each touch and its sometimes difficult to find the touch button in dim light such as evening time when you're going to turn it off or down. For example, Let's say you want to go from full brightness to a dim blue light at night time, you have to press the white light button a bunch of times to get through all the brightness levels until it is completely off, it doesn't always register pushes so you have to just keep pushing and often go past the OFF setting and back to full brightness again and just keep pushing until you finally find the off setting. Then you have to press the second button which controls the blue light a bunch of times as well until it's at the correct dimness level. Then you have to repeat the process all over again the next morning to bring the lights up to full brightness. After a few days/weeks/months of dealing with this you really have to wonder if spending more $$ is worth less hassle. If they just replaced the touch button with a regular set of dials where you could instantly crank it up or down it would be perfect. I'm still giving it 4 out of 5 stars just because it's such a great value. If you absolutely can't afford more for a light and can deal with the annoying touch buttons it gets the job done. Personally I'm returning this and looking into getting lights with physical or wifi controls with a timer to automatically change colors at night but they all seem to be in the $300+ range.

Okay.. so it’s VERY hard to get good pictures that reflect the true colors / light of this unit. The colors are BEAUTIFUL. This thing lights up my 29 gal Nano EXCELLENTLY. The blues on 100% makes my nem, zoas, and fish look absolutely gorgeous. Blues on 100, and Whites on 20%.. visibility is even better. Colors, brightness.. I am completely impressed. Again, the pictures DONT DO JUSTICE. Budget light.. best around. Get it. —- That all being said, I got this unit because I wanted the sunrise / sunset function. It simply.. does not work. I have set the timer. Adjusted the hours. Again and again. I have it set 9a - 9p. The TIMER works fine, It comes on 0%-100% right at 9am, and shuts off 100%-0% right at 9pm. To clarify, it goes from completely off, 0 power.. to full blast when coming on.. and when it shuts off it goes from full blast to straight off. For the life of me, I can’t get the rise/set function to work. I reached out to support and was told to read the manual. Whelp, the manual is clearly translated text and VERY unclear. Maybe i’ll figure this out some day. EDIT :: Adjusted my rating to 5 stars because after leaving my preview review, support reached out to me and actually told me how to ENABLE the sunrise/sunset function! After setting your timer you must HOLD DOWN the timer button for 5 seconds until the white lamp LEDS flash three times! Then your sun rise/set feature is enabled! Soooo happy support helped me with this, as I was rather upset about it. The user manual does NOT outline how to enable this function. Here in the end, I am now 100% pleased with this purchase for the good price.

My stopped powering up after a year of use that's is for the one star. It was bright setting at 75% at a depth of 18 inches. I would say no to water resistance. The body of the light is good quality as for durability like anything if dropped, it will fail. As for use. As for an ease of use just plug it into outlet at the time you want set to turn ON, then set it to how many hours to run every day.

Timer doesn't work? PAR not enough? Simply not true unless you got a faulty unit. The timer can be tricky, but you must READ the instructions! You can easily set your timer by the middle button. Simple as that. Many complaining that they cant set the time the light comes on or the light shuts off after you set it. When you plug in the light, the timer starts. If you want it to start at 9am, plug it in at 9am. If you want it to start at 10am, plug it in at 10am. It is literally that simple. The light goes on while you set it so you can view your settings. It auto shuts off after a minute or two if it is not within your timer settings. If it is, it will stay on. The PAR isn't enough? I'd check you PAR meter. I have this light over a small SPS tank and everything is doing great. Actually started bleaching things when I had it turned up all the way. I am getting the following numbers 6" under the water. I didn't test a few combos (B5:W3 or B5:W4), but you get the idea: B1 = 62 B2 = 109 B3 = 156 B4 = 202 B5 = 237 W1= 50 W2 = 91 W3 = 124 W4 = 156 W5 = 195 B1:W1 = 120 B2:W1 = 170 B3:W1 = 215 B4:W1 = 264 B5:W1 = 307 B5:W2 = 344 B5:W5 = 422 Overall, this light has great color and is more than enough light. I wish there was more blue (maybe swap a white or two for a few more blue), but for the price, you cant go wrong. If you want a great budget light with good control, active cooling, and great output, then this one is it. I will be picking up a few more for my other tanks.

This light provides decent flexibility and PAR for a nano reef tank. I measured PAR with varied settings (white and blues) and found a sweet spot for my tank setup. At full brightness (100% whites and blues) and the light at the lowest height possible for the light above the water, I measure around 400 PAR just below the surface of the water (6" below the light and about an inch under water). Near the bottom of my 12 gallon all in one, PAR drops to around 200 at full bright. I set the lights to 40% white and 60% blue for 200 PAR at the top of my aquascape and 100 near the bottom where my leather corals live. I love the color and usability of the light but the sunrise and sunset mode is a joke. I have another LED light that doesn't match the PAR of this light, and the basic controller of that light has an amazing built in sunrise and sunset. This light comes on instantly, based on the start time, at some level of brightness less than the programmed setting. Then after some period of time (listing states 30 minutes) it jumps to the full programmed setting. It's not a gradual sunrise, just on. Sunset is the same. Some time before powering off, it drops to some level of brightness less than the setting, but same colors, not dimming to blues/moonlight. Then after the programmed time has passed, it shuts off completely. My other LED light would keep blues on very low for about 4 hours after the whites went off and I loved the look of the nightlight. The whole plug it in to start the timer feature is ridiculous as well. Holding down the white and blue light buttons turns the light on and off. How hard could it be to have a similar feature to set the start of the timer? Lastly, the mount is not designed to support a rimmed tank. I was able to make it work, but it really needs a spacer to properly mount on a rimmed tank. This one works fine overall but sunrise and sunset are just terrible. The price is great if you can accept how it works, but I'll keep looking for a replacement.

Great lights. I have 2 ao30 on my 30 gallon fowlr and 2 ao36 on my 20 gallon reef. Been going strong for years. I just put them on smart plugs so I can control them from my phone and set a schedule.
