Maybe I'm just dumb and overlooked this but I was plugging in a new strand of LED strips while I was working on another project. I forgot about them and after about 30 minutes I started smelling burning and the strips had started melting the crappy plastic ring that binds them together. I assume this has something to do with the heat they are giving off and being so tightly wound up? Just worried about using them in projects if they are over heating. Thanks!
