LED spotlight bulbs generally offer longer service and higher energy efficiency than ordinary light bulbs. Generally, they are expensive, but a variety of colors are available, including bulbs that can have their colors changed with a remote control. You can replace a multicolored LED spotlight bulb in the same way that you replace a normal screw-in bulb. 

With these characters, led spotlights are particular ideal for performance stage, which usually needs different lighting effect to highlight the climax. This is what the general bulb can not achieve. For example, the stage play is performed on a stage without any special effect; therefore, proper led spotlight effect is benefit to the whole show.
