SEAOURA LED Aquarium Light, 24/7 Custom Timer, Power-Off Memory,7-Row LED 18-24in Full Spectrum Fish Tank Light, 8 Colors, 20 Brightness, Day&Night Cycle, Adjustable Mount for Freshwater Plant Growth

UPDATE #2 I upgraded my original review from 2-5 stars The customer service has been excellent from this seller. After I got my massive algae outbreak under control(see below) I purchased the upgraded version of this light which now has the ability to change brightness and color in 24/7 mode. The only way to tell if you receive the upgraded version ( because the old and new are currently mixed together at the warehouse) is to look at page 10 of the manual. If the top line on the page says time, color, brightness, you received the newer version. There is a battery backup in the control that saves current settings in case of a power outage which is a great feature. There are helpful programming videos explaining how to set up the controls, so it's not as complicated as it initially seemed. I am currently running 2 different sizes of this light on 2 separate tanks and have been very pleased with the newer version. My plants are doing great and there's no algae outbreak in sight. I will buy more in the future. ORIGINAL REVIEW. The controls are quite complicated to program on this very bright light. The biggest problem that I have experienced is that there is no way to dim the light intensity level when on 24/7 mode, which resulted in a MASSIVE hair algae outbreak that covered all of my plants, glass and rocks in a surprisingly short period of time. I have pulled out an entire tank full of live plants 3 times and dipped them in diluted peroxide followed by dosing of liquid carbon to try to keep them from dying due to algae suffocation. I have also removed all of the hardscape and scrubbed it down to remove the blanket of algae covering it as well. I have been doing 50% water changes every 3 days for the past 4 weeks because the algae returns so rapidly. I have even done total blackouts which helped, but once I turned the light back on for 2 hours per day, for the plants survival, poof! the algae returned with a vengeance. I have become a slave to my aquarium, spending many hours per week battling this scourge. It will be a miracle if my plants survive, because they are all currently melting. Once this algae sets in it seems to be very difficult to overcome. I finally resorted to replacing this high intensity light with the old kit light that came with my aquarium and so far the algae has not returned. UPDATE #1: Customer service reached out to me several hours after posting this review and offered me an upgraded replacement that allows brightness adjustment in 24/7 mode or a refund. Customer service has been excellent. I am willing to try the upgraded light, since I was happy with the quality. Regarding the difficult programming of the light schedule, customer service sent me more detailed directions and is also willing to help program specific times if needed. This company has been very willing to stand behind their product, which I really appreciate. I will be happy to try the upgraded version.

I have this light on a 40g Marineland breeder tank that has a 36”x18” footprint. This pic was taken with the light set at 10% brightness on full spectrum. Without a doubt, if you want to grow plants this is an absolute powerhouse. My Cichlid breeder tank has fake plants in it as the cichlids will eat live plants and in a 40g they serve to break up sight lines and reduce aggression. This tank was set up 2 weeks ago and is cycling with 1 fish in there. Programming takes some time but once you figure it out the light is awesome on its 24/7 setting that starts with a yellow sunrise migrating to full day sunshine to a yellow sunset to blue moonlight to off. All fully programmable for color, time and brightness. Well worth the extra $. If you want to grow live plants I can’t even imagine how well they would do under a light that can deliver so much power if you turn it up. I have to keep it lower with fake plants to avoid an algae bloom. With a tank packed full of live plants you’ll grow a jungle in no time.

Excellent plant light. Love the 24 hour mode where you control what color and for how long. My Anubis,Heavy rooting and stem plants are all thriving under this light. Looks great and easy to set up. Has a back up battery for power outages so it never losing the time.

It took a while to choose a replacement light for my fish tank. I needed something 24" wide to fit in my old fluorescent housing and this worked perfectly. The LED light quality looks good to me. I do not another one to compare it to so all I can say is that it is an good upgrade to my fluorescent light. I wanted a programmable one because I did not know what light level I would like. This was a good economical choice for me. I am still trying to figure out the programming. So far I have it turning on and off by itself. Brightness and color can be adjusted. There is also a night time setting. There are a lot of directions provided but there are so many steps involving pressing different buttons one or twice or holding a button down for 3 seconds that I cannot recall my choices fast enough to get to the next step before "programming mode" turns off.

This product is amazing.The only thing is that when you have to set app the timer and set the way you want your lights, there is no automatic on and off timer like other setups or pre Program , you have to program it yourself. But they do have directions on how to do so, it took me a minute to do it, and I'm kind of technical savvy, but I am most definitely buying more for my other fish tanks that I have. I love all the different colors that it has.The sunrise the sunset. And the moonlighting. But the light is perfect for if you wanna set up the lighting, the way you want it.And once you figure it out , it's easy. You can't beat it for the price point. The top of the light is not that hot.It is warm and you can touch it when it's on.It's not gonna burn you. Now we're gonna see how long it will last The light I have on. There is the 30 to 36 inch.

Seems to work fine. I purchased this to replaced a Hygger light that was very similar. However this Seaoura has more options and is easier to program. The light is a nice color and is very bright. I had to reduce mine to 75 percent on the daylight for my African Cichlid tank.

Bought as a replacement for our two gargoyle lizard tanks for a more expensive one that was gifted to me. The lighting is great. I have it set to rotate for the varying lighting. It was very easy to set up and program. I am glad I listened to the reviews.

This is my favorite aquarium light I own! Programming is a little confusing at first but no big deal. Super durable, I've used it for months now with no issue. Super bright, grows plants like no tomorrow!

Brilliant, and actually quite easy and instincitive to set up. I was worried because my other (smaller) seaoura had a very complicated 24/7 mode which in the end meant i was manually adjusting the light because I could not make it work. This one, I am relieved to say, was simpler to understand because it has a built in clock. The instructions are very clear, and i love that it has a QR code to the manual printed on the control box so you can't lose the instructions. In 24/7 mode it allows you to set 5 time segments, one of which is spoken for as it covers the time the light is off during the night. So you have 4 segments of light ypu can set. I wanted to mimic natural daylight cycles as closely as possible, which is both best for plants and fish welfare. Plants need the midday intensity for photosynthesis. Fish benefit from gradual transitions rather than sudden bright/dark changes. My corys especially get active during dusk and dawn. (I do the same with my heater, I let the temp drop by about 1 or 2 degrees during the night and then warm up again during the day, by having my heater plugged into a timer plug). The instructions suggest morning, daytime, evening and moonlight. I decided it made more sense to have early morning, midday, afternoon and evening. And then off during the night, of course. There are 15 mins of gradual transition between each segment, so say between night and the first segment, it will very slowly and gently come on. Not suddenly jump between levels. Segment 1 — Dawn (7am-8am) Warm amber/orange at 30% brightness. Mimics sunrise. Gentle wake up for fish, signals the start of their day. I didn't want it longer than an hour because then the amber becomes jarring, in my opinion. I might yet end up changing to violet because the yellow is quite out there and violet light is calmer for the fish and better for the plants. But I'm trying things. - 15 min transition - Segment 2 — Morning into midday (8am-1pm) Full spectrum (white light) at 70%. Plants start photosynthesising properly, fish become active. - 15 min transition - Segment 3 — Midday (1pm-6pm) Full spectrum (white light) at 100%. Peak plant growth window. Feel warned. This is BRIGHT but your plants need this and fish adapt, especially with good plant cover to retreat into. - 15 min transition - Segment 4 — Evening/Dusk (6pm to 10pm) Soft blue or violet at 20-30% dimming down gradually. Mimics sunset, signals wind down, absolutely beautiful to watch actually. I've currently chosen violet because my fish seemed happier in violet than in blue. Then 15 min transition to night off. I will adjust the hours every season change, at the minute we have some level of light between 7am and 10pm because the house is light all day as the days are long, but this longevity of light would just stress the fish out in winter. Im also conscious I moght get a lot of algae growth if I keep this up year round. So I will adjust it every 3 months to reflect the changes in sunrise and sunset, is the plan. Love that it makes this all so simple!!

muy buen producto
