There are two main types of led light source: one is led light bulb, which is commonly used in European lamps and modern lamps. The other one is led lamp beads. Led lamp beads are often used in crystal lamps. Crystal lamps are led lamp beads that are used to look especially shiny.
At present, the luminaire can not be used as light source with LED, no matter what type of light can be used as light source with LED, other lights can be selected freely, but crystal light can not be selected, the light source can only be the LED lamp.
