Dimming Operation
-
Output constant current level can be adjusted through input terminal of the AC phase line(L) by connection a triac dimmer.
-
Compatible with Leading edge or tailing edge triac dimmers.
-
please try to use the small power dimmer, have access to a wider dimming range, high-power dimmer is difficult to achieve the output current to zero
Do you need special Dimmer for LED lights?
The less electricity drawn, the dimmer the light. ... If you'd like your LED to be dimmable, you need to do one of two things: find LED bulbs compatible with traditional dimmers, or replace your current dimming switch with a leading-edge (LED-compatible) dimmer. A dimmer is need to be connect with dimmable led driver then the led light can works better.
