The invention relates to a lamp and a vibration absorption pad thereof. The vibration absorption pad of the lamp comprises a body and multiple vibration absorption pillars, wherein the body is provided with a first surface and a second surface which are opposite to each other, the first surface allows installation of a lampholder of the lamp, a vibration absorption ring is arranged on the body and comprises multiple arc vibration absorption grooves penetrating through the first surface and the second surface, and the multiple arc vibration absorption grooves are arranged at intervals; the multiple vibration absorption pillars are arranged on the second surface at intervals and used for being connected with a support plate of the lamp. The vibration absorption pad of the lamp has a better vibration absorption effect.
