LED Lamps with AC Dimmer: TRIAC or MOSFET — Compatibility Guide Feb 26, 2026 0 550 Short answer: There are two types of AC dimmers: TRIAC (leading edge — for incandescent bulbs, halogen, heaters) and MOSFET AC dimmer (trailing edge — purpose-built for LED lamps). If an LED lamp flic... ac-dimmer Arduino LED MOSFET trailing-edge TRIAC tutorial Read more
Trailing Edge vs Leading Edge: Which Dimmer Method to Choose Feb 26, 2026 0 653 Short answer: Leading edge is the standard TRIAC dimmer — it opens the load in the second half of each AC half-cycle (best for incandescent bulbs and heaters). Trailing edge is a MOSFET dimmer — it op... ac-dimmer Arduino leading-edge LED MOSFET trailing-edge TRIAC tutorial Read more
LED Flickering with AC Dimmer: TRIAC or MOSFET — Causes and Fixes Feb 26, 2026 0 533 Short answer: LED flickering with an AC dimmer has three distinct root causes. Types 1 and 2 are caused by TRIAC architectural incompatibility with LED lamps — the hardware fix is a MOSFET AC dimmer (... ac-dimmer Arduino ESP32 flicker LED MOSFET TRIAC tutorial Read more
