Renoliss USB 66FT 200 LED 16 Colors Changing LED Fairy String Lights with Remote, Red White and Blue Lights with Green Wire & Timer Function for Holiday Decorations, Multicolor & More Solid Colors

If you're looking for the lowest cost per LED for WS2812b LEDs, this is the best I have found so far.Pros:- ~20m of LEDs!- Weatherproof ARGB- These do appear to be individually addressed on the built-in controller (2812s and not 2815s)- Power rail in parallel so even brightness all the way to the end of the stringCons?- Built-in controller doesn't have a music mode- Color and fade transitions are a little jittery (probably a low-speed controller chip)Honestly the cons are a bit of a stretch.- The controller is fine, and if you don't like it you can make your own with arduino- And the fading is absolutely fine for 99% of your use case.- The remote is fine, though the "preset buttons" on the bottom are for modes that I think nobody will ever use, but the mode button lets you cycle through to find the one you want.- Brightness is fair - good for decorative lighting, but not gonna blow away your neighbors (or overload a cheap USB charger).I rigged up a rudimentary power meter with a smart outlet and a USB charger. This has a fairly low resolution and low refresh rate, but it works. I measured a peak of 5.5 watt power draw, so roughly 1amp. With the included controller you should have no trouble powering these things out of the box with any USB power supply.I bought these because they were the most cost effective way to get 2812s I have been able to find, short of custom ordering a bulk spool off alibaba. 20m per string gives me plenty of length to cut from for various other projects - getting a controller and a remote is just icing for the leftovers. Some of these I will wire in parallel into a more expensive music-sync controller. Some of these are going into custom arduino projects. Some are just going up around a christmas tree as-is.If you need ARGB LED strings, whether for decorating out of the box or for cutting up for custom projects, buy these now!

Great quality for a great price. I purchased these lights because I was worried about the danger of incandescent light bulbs. These LED bulbs stay cool, even after hours of use. I was pleased will all the modes, but I do wish that there was a "stable" non-flashing multicolor option on the remote. There is a slight delay on the control, and the signal isn't incredibly strong, but this is only a minor inconvenience.There is one bulb that behaves out of sync with the others, and turns the wrong color on certain settings, so I just taped over it, which works fine since the bulbs don't get hot.If you're looking for the highest quality, flawless product this isn't for you. However, I believe I got much better quality, customizability, and more lights than other lights competing at the same price.

Used for our golf cart and they work great. Like the ability to choose colors and blink rate.

Comes with a remote with tons of settings. Easy to set up and plug in. Set them up around my kids beds and they fall asleep with them every night. I usually set the timer so they turn off after like 4 hours.

This looked great inside, but it only lasted one night in the rain. There was condensation in clear plastic gizmo near the plug even though we covered it - maybe if that had been better protected. But it's dead now.

The media could not be loaded.  I have been using these for years. The only draw back to this brand is it doesn’t have an app to connect to your WiFi to control them

Worked when I got them, after I put them on the tree only about a dozen of them came on. Also I noticed that the buttons didn't turn on the correct colors.Take your own chances

These were much longer than I expected and VERY bright. The colors are vibrant and the color options are great. My only beef is that the remote control doesn't provide enough description for the different modes and settings... so you find yourself clicking through a LOT of options and then having to go back through a second time to find the one you liked the most. They remember the setting between power on/off, though, thank god. I am going to buy more of these - they're excellent.
