These lights worked perfectly for what I purchased them for - as part of the backdrop for my Christmas pictures. They are a great, long length and width and shine brightly, but they are not overpowering. I had no issues stringing them up at all. They have a steady on mode as well as several different blinking modes. My only complaint is that the plug did not fit into my standard outlet - it was very loose and kept sliding out, so I had to tape it in to use it. Also, there is no off switch, so these have to be unplugged when not in use. Like I said, though, they worked great for my intended purpose.

One of the main questions are customers ask us is “what is the difference between continuous and strobe lighting?” Continuous lighting uses a constant light source to light your subject, meaning that your lights will stay on during the entirety of your photo shoot. Continuous lighting is recommended for beginners. Strobe lighting uses a flash of light at the moment your camera shutter opens to illuminate your subject. Many professionals use this type of lighting because it offers more control of the light.
