From residential lighting to large commercial spaces, the right dimming method can make all the difference in lighting comfort and control flexibility. But should you choose TRIAC, 0-10V, or DALI dimming? Let’s break down how each works and where it performs best.
TRIAC Dimming：Traditional and Retrofit Choice
TRIAC dimming controls brightness by cutting the AC voltage waveform's conduction angle.
Key advantages:
Low cost and wide compatibility
No additional wiring needed
Perfect for residential lighting and traditional fixture retrofits
Suretron's TRIAC dimming power supplies offer both leading and trailing edge dimming modes, covering both constant voltage and constant current solutions with smooth, flicker-free performance.
0-10V Dimming: Stable Solution for Large Spaces
0-10V dimming uses an analog voltage signal (0V = minimum brightness, 10V = maximum brightness) to provide linear, stable dimming.
Market research shows 0-10V dominates commercial and industrial applications, with Maia Reports estimating its 2024 market revenue at $3.574 billion—about 3.7 times that of TRIAC.
Suretron's 0-10V dimming power supplies are widely used in offices, shopping malls, and factories, offering stable performance across multiple power segments.
DALI Dimming: Core of Smart Lighting
DALI (Digital Addressable Lighting Interface) is an international digital communication protocol enabling:Precise dimming，Individual lamp addressing，Group control，Scene setting，Bidirectional feedback
Wiseguyreports data shows DALI's 2023 market size at $4.9 billion, expected to grow at over 8.0% CAGR through 2032.
Suretron's DALI dimming power supplies comply with international standards and are ideal for hotels, commercial complexes, and airports requiring intelligent management.
