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.

Introduction to Legend Tech DIMEZE™ Fast Tester and Using Halogen Driver for Dimmable LEDs

Technical support is a key business priority for us. The Legend Tech DIMEZE™ Fast Tester is a simple adaptor for Architect and Interior Designer customers to connect our devices for mock-up purpose. In the 1st part of the video, we demonstrate how easy it is to use the Fast Tester for a given dimmable fixture evaluation.

A common question in LED retrofitting is whether the already installed Halogen driver (e.g. 60W 12V Halogen Power Supply) can be used for LED lamps, which normally requires a LED Driver. In other words, “Can I just unplug the Halogen lamp and replace it with a dimmable LED lamp  (e.g. Philips MASTER LED 7W Dimmable MR16), and connect with your dimmer directly?”

In the 2nd part of the video, we use the Fast Tester to quickly find out the answer to the question. Besides LEDs, our dimmers are capable of controlling Halogen, Incandescent, and Dimmable CFL. So to find out the answer to that question, we replace the Halogen bulb by the LED and you'll see again the dimming operation works as normal. The reason for this is because the output power of the Halogen driver is usually much higher than that for LED driver. In this case, we have a 60W Electronic Transformer for the 12V Halogen and a 10W Electronic Transformer for the 12V LED. So generally speaking, the answer to the question is a “YES”, which means direct replacement of Halogen by Dimmable LED lamps is possible.
