Besides energy saving, controllability is the next highly expected feature of LED Lighting over Traditional Lighting. However, such a control aspect seems to be missing in daily applications. Since 2015, we've been developing & marketing Phase Dimmers* and related products to address LED dimming control

Driven by our project field experience, we developed a new type of Tunable White control using Phase Dimming & 0-10V technologies, which gives our Tunable White Controller (DZ1G300TUNE) & Dynamic Lighting Controllers (DZ2G300TUNE_TOGG / _PUSH). It's our goal to lower the technical and costs barriers for different Circadian Lighting or Commercial applications that desire Multi-Purpose Lighting.

* Our 450W / 220-240Vac Single Live-wire Operational Trailing-edge LED Phase Dimmers released to market includes DZ2G450DIAL & DZ1G450CAPS (2015), DZ3G450DIAL (2017), DZ4G450MULT (2018). In 2017, our DZ3G450DIAL was listed as a SORAA® Compatible dimmer. In Q2 2021, an Enhanced version of DZ3G450DIAL has been available.

In this Application Video Library, we shared a number of interesting topics on LED dimming or how our products can be applied in different scenarios.

Legend Tech DIMEZE™ Deep Dimming Compatibility with Meanwell TRIAC Dimmable (PCD Series) Drivers

As we’ve emphasized, Satisfactory LED Dimming performance relies on quality products from the different catalog to work hand-in-hand. Shortly after we’ve started our own Marketing, we encountered numerous inquiries about which TRIAC Dimmable LED Drivers would our dimmer work with. As time progresses, we see More and More LED Dimmable Drivers Capable of Providing Reliable performance in Low Dimming Range

But still, these type of questions remain to be some of the Most Frequently Asked Questions. Unfortunately, we do not foresee this would be coming to an end in a reasonably short amount of time. 

While our Phase Dimmer and 1-10V Controller products are not limited to working with Mean Well LED Drivers, it’s always good to establish some kind of benchmark with major players for a common ground of understanding. Mean Well ( is One of the Trusted Global Supplier in LED Lighting industry with a Good Market Reputation and a Strong Product Portfolio Coverage for many LED Lighting Fixture Driving Applications

In this video, we’ve demonstrated Satisfactory Deep Dimming performance with our Gen 2 Phase Dimmer, DZ2G450DIAL and the Mean Well TRIAC Dimmable LED Driver, PCD Series. Different LED Driver manufacturers may have different application focus. We can see that Mean Well PCD series consists of 21 models covering a mix of High Voltage (108V)-Low Current & Low Voltage-High Current (2400mA) portfolio for 16 / 25 / 40 / 60W applications

PCD (Leading & Trailing Edge Dimmable) / 180-295Vac (B Series) Part Number Notation: 

  • PCD-16-xxxB / 16W Dimmable, Constant Current Output in 350 / 700 / 1050 / 1400 mA
  • PCD-25-xxxB / 25W Dimmable, Constant Current Output in 350 / 700 / 1050 / 1400 mA
  • PCD-40-xxxB / 40W Dimmable, Constant Current Output in 350 / 500 / 700 / 1050 / 1400 / 1750 mA
  • PCD-60-xxxB / 60W Dimmable, Constant Current Output in 500 / 700 / 1050 / 1400 / 2000 / 2400 mA
