Lamps explode if they are used beyond certain rated life. Also, if lamps are used roughly, they can get hot, and if not properly cooled down, can explode. This happens when the heat from the lamp becomes too much for the metal parts of the lamp, and it starts to melt. Lamps that explode can cause serious burns and injury. To avoid getting a projector lamp that explodes, be sure to keep it cool by properly shutting down the projector and getting it free from debris. If you do experience an explosion, please contact the nearest emergency service.
