Input/output is AC100–240V, 1.5A max, up to 400W@220V incandescent/halogen or 200W@220V dimmable LED. Control it from a ZigBee hub (Philips Hue, SmartThings, Tuya, Echo Plus, ConBee, Hubitat, Home Assistant ZHA/Z2M), a GLEDOPTO 2.4G RF remote, or a wired push switch—no hub required for local dimming. Trailing-edge dimming reduces flicker and lamp stress; minimum brightness is adjustable; soft on/off and power-fail behavior are supported. Never connect non-dimmable loads—large inrush current can destroy the triac/MOS stage. It cannot drive 12V/24V RGB/RGBCCT tape and cannot control SPI/DMX addressable strips.
Ultra-Mini AC Dimmer: 42×38×17mm, ~30g, quick-connect 0.5–1.63mm² wire; hides behind wall switches / in EU flush boxes where GL-SD-001’s 48mm body is tight.
ZigBee 3.0 + 2.4G RF + Push: Hue / SmartThings / Tuya / ConBee / Hubitat / HA ZHA-Z2M; GLEDOPTO RF remote; external push-dim switch supported.
Trailing-Edge Dimming: Smoother with dimmable LED lamps than crude leading-edge modules; adjustable min brightness stops low-end flicker; soft start extends lamp life.
Correct AC Load Ratings: 400W@220V / 200W@110V incandescent+halogen; 200W@220V / 100W@110V dimmable LED+drivers; 1.5A max.
Safety First: IP20 dry location only, qualified electrician install, N+L required, non-dimmable loads forbidden, over-temp/power-off protection
