Excuse me, does anyone know what GC-G and GC-M on the LED-driven power board mean? Who produced the power supply?

GC-G and GC-M are the abbreviations of logo on the circuit board of high-power LED driving power supply produced by Shenzhen Guke Semiconductor Co., Ltd., GC is the abbreviation of GOODCOO, and -G stands for the 85V-265V input of wide-voltage driving power supply, which is installed in the lamp holder of GU 10 (the lamp holder we use every day is card-type) or E27, indicating high-voltage input. -M represents the input voltage of 12V or 24V, and the power supply installed in the lamp holder of MR 16.
