MUCH Underwater Pond Light Remote Control Waterproof IP 68 Submersible Spotlight with 36 LED Bulbs 7.5 W Multi-Color Spot Light for Aquarium Garden Pond Aquarium Tank Fountain Waterfall (Set of 4)

I was almost return it, because the instruction says "recommend for indoor use", the 12v adapter is not waterproof. I was able to find a waterproof box from Amazon to protect it, so I installed it. It came out really beautiful and I canceled my return. I used it play light show for my 165 gallon outdoor pond. It's easy to attached to the pond wall and able to turn angle. Very satisfy of the result.I had used this light in my small pond for couple of months, light is still working great. Because the pond wall getting dirty, the light could’t ahere to the wall, they flow in the water.

I've had these going on a dusk/dawn timer for about two months with a hitch. They constantly change colors when focussed on a water fountain in our yard. You can't select a color, they change all the time. I'm not using them submerged, but on the ground facing the fountain. I water all the plants where the lamps are located, and they get plenty of water too! No problems. I'd buy them again.

Awesome when they were working for only three weeks..... would not suction, kept floating but fixed that with sticking them to tiles in my pond. Three weeks of use and then they no longer work. Don’t waste your money on these

Okay, this is one of those things where if it is the right product for you, you are going to love it but it may not be the right product. The lights change color automatically and provide a really nice ambience for a fountain that I just put in the yard. I have read other reviews that said the electrical connector tends to corrode so I coated mine in silicone sealant before I installed it. I have had no problems whatsoever. The length of wire between the lights is relatively short and cannot be easily extended. This is fine for the application that I am using it for, and in fact is just right but depending on your installation, it may not be a good choice. People have complained that the suction cups don't work. I can see why. They are quite flimsy. For me, it is irrelevant because I'm not using them as suction cups. I have them permanently bonded to flat cobblestones using JB Weld and set them around the fountain. If you are anticipating using the suction cups to attach to the smooth side of a pond, you might be disappointed. The lights are bright and being LEDs, are economical to operate. The only reason I did not give them 5 stars is because the lenses on all of the lights have become crazed - almost like you have rubbed them with fine sandpaper - after just a couple of months. It is really not noticeable when the lights are on and does not seem to affect the light output but it is annoying and I can see where these lenses might need to be buffed out periodically. That being said, I think they are a good buy for the money. Think carefully about how you are going to use these lights. If they really meet your needs, I think you will be happy.Update 3/12/20: Although the lights worked fine on initial installation, I only got a little over a year useful life expectancy. The housings all started to leak and the LED lights shorted out. If these are going to be used in a non-harsh environment or for an indoor display they will probably be very durable. For outdoor use in or near a water source, do not expect much longevity. They may still be worth the price depending on your application.

These are used in a waterfall fountain in my backyard. They look great and use very little electricity.

Used these lights to light up a backdrop and these lights really worked out. These can be used outside of water and do a great job.

From the beginning 1 of 4 lghts was weak. Now they all start flickering. Not expensive so i guess i got what i paid for.

Compared to other water proof pond/pool led lights I currently have, these are very bright and the changing colors snap from one to another and do not blend one to another color. The suction cups do not work either in water or out. I had to use some screws to hold them in place when mounted on wood or tent stakes when used on grass, earth, or mulch. Finally these babies float. Yet they are buoyant; they shoot right up and float. I used some in my fountains and had to hold them down with fist sized stones. I never expected this. The last sets I bought from another supplier were self weighted and sat neatly under the water of my fountains. The three star rating is because of the buoyancy issue. I really had a good laugh at these floating "underwater" oxymoron pond lights. Caveat emptor folks. They weren't cheap. I spent over a hundred bucks for 1 set of 4, 2 sets of 2, and 2 singles.
