Abstract: A telescopic plant light comprises a plurality of light bars and a drive device. The light bars are arranged side by side. Every adjacent two of the light bars are connected by a linkage telescopic mechanism to move toward each other or to move away from each other. The drive device is electrically connected to each of the light bars. Through the linkage telescopic mechanism connected between every adjacent two of the light bars, the distance between every adjacent two of the light bars is adjustable according to needs. In normal use, the distance between every adjacent two of the light bars can be increased. When not in use, the light bars are moved to be close together, so as to effectively reduce the space occupied by the product. It is convenient for storage, packaging and transportation. The product is very convenient to use.
