The LED luminaire is hot to touch. Why is this?


The LED chip, or light engine produces heat. This needs to be dissipated as quickly as possible. This is normally by using a heat sink. This often has fins. Cool LEDs are more efficient than hot ones. They also have a longer life. Of course, higher power LEDs generally run hotter than low power ones because of the extra heat to remove.
