Abstract: Disclosed is a LED grow light with a cold light source, including a cold light source body fixed on a lamp support of a HID lamp, and an electronic ballast and two wiring lamp holders are arranged on the lamp support. The cold light source body includes a cold light source and a heat sink, and the heat sink includes a housing and side cover plates located at both ends of the housing. Heat dissipation channels are formed in the housing, and a plurality of heat dissipation fins are arranged on the housing. An end cover is installed at an input welding spot, screw holes are machined at the top of the housing, each screw hole is connected to a screw rod that penetrates through the fixed support and is fastened and connected by means of a screw, and the fixed support is further connected to the lamp support.
