There are LED floodlights, LED downlights, LED corner lights, LED track spotlights, LED ceiling spotlights, LED underground lights, LED underwater lights, LED wall lights... There are many names, but I I think you must first understand one thing. LED refers to a new combustion light source. It is made with a new technology and is very different from the tungsten filament burning light source we usually use. Generally, LED is LED , its lamps can be interchanged with the lamps such as floodlights we use now, the only difference is the light source.
