Seaoura SR-657 24/7 LED Aquarium Light Full Spectrum

Love these!! I had to exchange one of the two that I bought as the cord was damaged, but other than that, they are great for the money. I really appreciate the battery backed timer function. Unlike some others, I did not find it difficult to set up. I use the two on a 6 foot tank, but really wish they would make a larger one or provide a simple block with a couple of bars to allow the two to link together. I’ll probably 3D print something.

I have these in a few sizes, but this is the only one I've actually set up. It's a pretty good value for the functions. Battery backup was on the top of my list for features, most lights with built in timers won't keep time during a power outage but these don't have that issue. A battery is included but it's an odd size button cell so you might want to order a few as backup when you get it, it wasn't something I keep around for multiple other like a 2032, it's some smaller battery I've already forgot the type, 1220 maybe. The instructions are adequate to set it up on both 24/7 or on/off, I've got it running on the 24/7 setup and it's nice having more subdued colors for a longer time period as an accent vs full blast for part of the day, though you can customize the length of all 5 slots. Quality is ok, this particular unit doesn't sit perfectly flat on the tank, it's only a few mm from a small warp but it is somewhat annoying, neither of the longer units I have had this issue when I tested them. Most of the cheapo light bars have a plastic housing, this is aluminum, although it doesn't have heat sinks, but it doesn't really get hot so that doesn't matter. Plenty bright for shallow tanks or for growing rheophytes and other low light plants and it has good color. I think the timer box placement is a little odd considering it's not waterproof, it's maybe 18 from the light itself but it seems like it would be better off further away just to reduce splash since in my case it sits against the bottom of the outside of the tank and I am not gentle with water changes, though I haven't had any issues yet. These are the only 24/7 lights I've tried, all my other lights are on off only, some with manual dimming, running on wifi timers. I live off grid, and while my power system is more reliable than PG&E for downtime, I do have occasional outages or maintenance, and I would lose my mind if I had to reprogram everything each time I shut down the system, so I am really happy with the battery feature.Overall these are great lights for the price, I don't have money for the 2 big name aquatic plant light brands and I think this is about as good as you can get on a budget. I forgot to get pictures of it and the tank is sleeping right now, might add some if I remember.

Beautiful and easy to put together. Wonderful addition to my tank!

This light is awesome for the price. I love the 24/7 function with the battery back up! My plants are taking off! I had to get another tank to propagate the clippings! I ended up buying two others from the brand for my other, smaller tanks.

I love that it has battery backup for power interruptions. IP68 water-resistant rating is nice. I use the 24/7 setting which looks great; however, I wish I could program the brightness across the various daytime phases. I assumed I could do so, but it turns out it's only for regular mode or day/night mode (which does not do dawn or dusk). Regardless, I love how the dawn and dusk stages make my glowlight tetras and cherry shrimps pop. Overall, happy with the light.
