I bought the 66ft version in “Warm White”. The plug is a transformer and plug that are connected with a plastic screw (see the plug pic), then there’s a black mode controller that acts as an on/off switch. The mode controller includes 8 modes, most of which are various blinks / slow fades. I honestly just leave them on the steady on mode lol. There is 17 feet of connective cord between the plug and the start of the string lights (the string lights are 66ft). That’s probably great if you are setting up in a venue, or have to plug in across the room. The end of the string lights has a connector for another string of lights, and you could buy multiple boxes of these if you need that. The lights are the perfect level of brightness and warmth, so I’m happy with these! I have most of the lights behind my bed, but I have a bunch of extra length wrapped around my headboard.The only thing that would make these awesome would be a little remote controller or app, but I also like this price point and would rather manually turn them on than pay any more.Easy to set up and they work greatThese lights are beautiful, lightweight, easy to use and look awesome around my living room ceiling! The setting control is super easy to use. I would definitely recommend this product.Amazing for what you get for the price and the length of these lights!Bought these for use in a temporary apartment as a way to add soft ambient lights throughout the room. I pinned these to the ceilings around the perimeter of my living and dinning room. We just leave them on the constant on position but the controller has several settings to choose from. It provides enough light to see, not hurt your eyes, and brings a little fun to your room.I bought another set of these lights because they are amazing. They are long lasting and don't burn out like Christmas lights.I got it recently and it’s great. Not too bright (I hate bright lights because they hurt my eyes at night) but bright enough to light up my room so I can clearly see. I’d highly recommend them over Christmas lights in your room. They don’t get hot and they use less energy.
