1 Set of 4pcs Submersible 36-LED RGB Light Waterproof Underwater Fish Tank Garden Pond LED Aquarium Spotlight Lighting

In every respect, these lights have worked well in my application. The lights have not failed, are quite bright and we're easily controlled for on/off with the purchase of a remote controlled AC switch found on Amazon (Woods 32555 Outdoor Remote Control Outlet Converter Kit.You should know that 1) the cable length between lights is on the short side for some applications. In the fountain I used (3 tier apple barrel) it was perfect. Beyond about a meter though, you will have to cut & splice in more cable and 2) the light color changes are NOT synchronized. This may be a small issue for most, but some prefer a synchronized transition between all 4 lights.

So, these aren't super bright during the day, but in my 4 foot deep koi pond, they give off enough light so that you can see the fish at the bottom at times during the day when you couldn't without them. Where these lights really prove their value is at night when it is really dark. I just put these in my pond, and at 9 at night when it is really dark out, these lights light up the entire pond, and make it look like the fish are swimming through a laser light show. If you are only ever going to look at your pond during the day, I would say you should go with ones that don't change colors because they dedicate all their energy to creating bright light, rather than switching between light colors. If however you are ever going to look at your pond at night, these make it look amazing in the dark.

These lights are simply okay... Nothing more, nothing less. I was disappointed to find out that you cannot stop the colors from changing automatically. I guess I should have done more research. They also seem to get out of sync after being on for about 15 minutes, which causes each light to display a different color over time and look very odd. The underwater feature is pretty cool and filled the void in what I was looking for but if I could do it again I would have most likely paid some extra money for a different product.

Purchased these in May and installed them in late June. The lights stopped working properly and the remote will not let us change the mode or color of the lights. Very disappointed with these lights. We use them in a small garden fountain that looked great when the lights did work.Sent a request for replacements, but as yet have not heard from the seller.

great product, very bright at night. so far so good; the only thing is that the colors are not synced, but still looks nice. It is very light weight, tied each light to a small flat 4'x4" tile so they don't float. I only had them for a week, will see if they are ok after few months

The lights are very bright and clear and the chords are long enough to allow the lights to fit in each corner of our pond. The only reason they didn't get five stars is because the suction cups won't stick to the bottom of our pond so the lights just float on the top for now.

Lights are good. They are very bright and work great! The suction is not good. Actually, the suction does not work at all. The lights just float at the top of my pond, which is fine. Other than that, good lights and definitely worth buying. I've already bought 3 sets of them.

The suction cups are ok, but harden and then no longer stick to the pond liner. I only have them suspended about 1 inch below pond surface.UPDATE - After two pond seasons, April - October, they are leaking and failed. They have a circuit board in each light that cannot tolerate any water. I kept them indoors from October to April, and they STILL leaked , and then failed. Water and Electronics do not mix well. Somehow water got past the O-Rings on two of the lenses, Not sure how, never got bumped! I put silicon grease on the O-Rings to prevent water leakage as well. Too bad, Would not be bad if I didn't pay so much for them back then, the price dropped quite a bit since.
