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.

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.

So far quality and functionality seem good. Great Price for a budget reef build. Time will tell what sort of coral it will support. Should be fine for soft coral and some LPS, but looking to eventually get a few sps once tank is established. Will update if I need to upgrade to AI prime or not once we get there.
