Some LED drivers are loud and flicker when dimmed. Others stay silent and smooth. The reason? Different dimming technologies.<\/p>\n\n\n\n
Leading-edge dimming (TRIAC) cuts the AC voltage at the beginning of the wave. Trailing-edge dimming (ELV or MOSFET) cuts it at the end. This timing difference affects compatibility and performance.<\/strong><\/p>\n\n\n\n
Leading-edge vs trailing-edge waveform<\/figcaption><\/figure>\n\n\n\n
LED drivers are not simple resistive loads. They have capacitors, inductors, and ICs that react to voltage patterns. A mismatch between the driver and dimmer can cause visible problems. That\u2019s why we need to look closely at compatibility.<\/p>\n\n\n\n
Mismatching a dimmer with your LED driver can cause customer complaints, safety issues, or product failure.<\/p>\n\n\n\n
Using the wrong dimming type leads to flicker, shortened LED life, and even overheating. Matching ensures safety, performance, and peace of mind.<\/strong><\/p>\n\n\n\n
Some brands encode dimming type in the model number. Others mention it in the “dimming compatibility” section. Never assume\u2014always verify.<\/p>\n\n\n\n
Some generic drivers only say \u201cdimmable\u201d without clarifying the type. In these cases, further testing is needed (more on that below).<\/p>\n\n\n\n
Even if the label is missing, your eyes and ears can give clues about the dimming method.<\/p>\n\n\n\n
Buzzing, flickering, or poor low-end dimming usually point to TRIAC issues. Smooth, silent dimming is a sign of ELV or trailing-edge control.<\/strong><\/p>\n\n\n\n
Trailing-edge dimmers allow smoother control at the low end of brightness. This is especially important for mood lighting or residential use.<\/p>\n\n\n\n
I always carry a test dimmer box with both TRIAC and ELV dimmers. I plug in unknown drivers and observe behavior. This saves time and helps avoid installing incompatible systems.<\/p>\n\n\n\n
Still unsure? Here\u2019s what usually works together in real-world projects.<\/p>\n\n\n\n
Halogen-style dimmers (TRIAC) work with some LED drivers, but for modern performance, trailing-edge dimmers pair better with most dimmable LED drivers.<\/strong><\/p>\n\n\n\n
For residential or low-wattage LED setups, always go with trailing-edge dimmers. They offer better performance, lower risk of noise, and higher customer satisfaction.<\/p>\n\n\n\n

With so many dimming types and compatibility risks, it’s easy to make a mistake. That\u2019s why we made it simple.<\/p>\n\n\n\n
At BOQI, we clearly label every dimmable LED driver with its supported dimming type\u2014TRIAC, ELV, or 0-10V\u2014so professionals don\u2019t have to guess.<\/strong><\/p>\n\n\n\nboqi Dimming type clearly marked<\/figcaption><\/figure>\n\n\n\n
Clear Labels:<\/strong> Every driver includes dimming type on the case and box.<\/li>\n\n\n\n
Datasheets with Waveforms:<\/strong> We include dimming waveforms in every spec sheet.<\/li>\n\n\n\n
Testing Support:<\/strong> We provide compatibility testing if needed.<\/li>\n\n\n\n
Custom Design:<\/strong> Need dual-dimming? We offer combined TRIAC + 0-10V designs.<\/li>\n<\/ul>\n\n\n\n
When I launched BOQI, one of my goals was to make life easier for buyers like Jacky. I know how stressful it is to manage compatibility across large product lines. So we focused on clarity, testing, and support. It\u2019s how we became a reliable dimming partner for so many brands.<\/p>\n\n\n\n
