LED Floodlights are lights which use broad beam technology for illuminate a huge area. This thing you don't use in indoor rather you use it for huge area like stadium, parking lot, outdoor industrial sites and many more places where high intensity lighting required. This lights are really energy saving if you are using them instead of conventional florescent lights or any other lighting technology.if you are musical then you can find at concerts or dramatic plays.
