I have mentioned on this blog in the past that you need to be careful about the quality of the LEDs that you purchase. Here's a prime example:

What you're looking at is an LED panel. This photo was taken at a local Home Improvement chain store. Notice that the lower part of this panel is already burning out. These panels are supposed to last over 30 years and yet their display model is already failing. These panels aren't cheap but they are good value if they last 30+ years but not if they're going to burn out within a few months or years. Don't purchase cheap LED lights. Remember that you get what you pay for!
