LED Dimming has been a common lighting requirement in Today's Professional LED Lighting / Interior Design. But for many, who are in LED Lighting Design / Interior Design / M&E Consultant, they might have found different Reliability and Performance problems when using Traditional Incandescent Dimmers (a.k.a, TRIAC Dimmers) to realize LED Dimming. There are already many websites saying that LED Dimming requires a new type of Dimmer. It's our intention to create our Application Video Library to explore different LED Dimming topics so that the relevant parties would be able to visualize it than simply reading another technical article online.

To provide a simple-to-use and cost-effective LED Dimming solution for customers’ transition to Professional LED Lighting effect, our 450W / 220 - 240Vac Digital Phase Cut LED Wall Dimmers are designed for LED Deep Dimming. Not only are backward compatible to single Live-wire operation for TRIAC Dimmer Replacement, our LED dimmers have Other Benefits from Digital Processing, which upgrades Single Pole Dimmers with new features matching with today’s market needs.

Gen 3 LED Phase Dimmer
With our past effort, our Gen 3  LED Dimmer, DZ3G450DIAL, is officially listed on the leading Professional LED Lighting Manufacturer, SORAA®’s Compatibility List for its Professional LED Lamps. Not only that, our different solutions have been using in multiple projects by some prestigious customers, who encountered LED Dimming problems for their Interior Design projects. By working with LED Driver and Lighting Fixture Suppliers, Designers and Electricians, even Retailers, we've gained a comprehensive end-to-end understanding of the overall LED Dimming / Professional LED Lighting applications. This extensive Marketing experience also fuels our continuous product innovation for LED Dimming applications!

Gen 4 LED Phase Dimmer
To address Hospitality, Office, Retail and Residential Lighting applications, our new Gen 4 Multi-Way LED Dimmer, DZ4G450MULT, does not only integrate Light On/Off, Deep Dimming Up/Down and Scene-Setting features to a single button, but it also has a Unique Feature of being able to Connect Multiple LED Dimmers to Control the Same set of Lighting Fixtures at Different Locations, without SPDT switch nor Mobile APP . This is something not found in the textbook and is a useful new product to the Lighting society!

Legend Tech DZ1G1TEN ( 1 - 10V Controller ) with Electronic Dimmable Ballast

Legend Tech DIMEZE™ DZ1G1TEN 1-10V controller is designed for LED dimming applications. On the other hand, dimmable ballast has a different circuit structure, which introduces a potential shielding concern for simple 1-10V controllers in such application. Shielding is a common electrical topic, which basically means external interference to the control signal running via a cable.

Here, we have an Electronic Dimmable Ballast from HEP (model # DS214-35) that is connected to two 14W T5 tubes and our DZ1G1TEN. For this type of application, please make sure the Earth wire must be connected to the ballast (no floating or NC). If it’s floated, when you touch the metal casing of the ballast, the T5 brightness level would change.

It’s important to realize that in the typical ballast circuit design, the current supply from the AC to the 1-10V control terminals is done via a “transformer”. After we opened this particular ballast, we’ve found that the current is further reduced by a thermo-sensitive resistor, thus the actual current that flows in-and-out of the 1TEN controller via the DIM+ and DIM- control wires would be even smaller. That means the controller would be highly subject to external interference. If you touch the controller’s wiring terminals by hand, you’ll find a brightness drop from the T5 even with the shielded cable that we now use for the 1-10V terminal connection; the brightness drop would be worst if non-shielded cables are used combined with a floated Earth wire to the ballast. Under the normal scenario in which no touching to the lighting equipment and that the dimmer is installed properly inside the wall box, the DZ1GTEN controller would function with the Electronic Dimmable Ballast as we shown in the beginning of the video. For our suggestion in this scenario, please see relevant topic in our Support section.


If customers decide to use our DZ1G1TEN for ballast dimming application, please be aware of the potential shielding issues as covered. For us, using our device as-is for such application is not recommended. If the shielding issue still remains after you’ve tried the various common approach to fight the issue, our recommendation is to switch to a 0-10V controller (above right), which has its own AC power supply (4-wire terminals: 2x AC and 2x Control), which should be much more stable against the mentioned shielding issue. 

At last, we emphasize that the DZ1G1TEN is designed for LED dimming. For its applications with different LED drivers, please refer to our other videos in the library.
