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!

SORAA® Constant Current LED MR16 vs. 12Vac LED MR16In one of our previous videos, we looked at the Backward Compatibility issue between the LED MR16 (aka. GU5.3) and the 12Vac Electronic Transformers (ELV). Such incompatibility is common and can be recognized as soon as the Halogen bulb is replaced by the LED MR16 bulb and found flickering even when no dimming is involved (only On-Off).
Besides the compatibility issue, dimming performance of the 12Vac/dc LED MR16 bulbs would be largely limited to the integral LED drivers. In this video, we look at an alternative solution, which requires the use of Constant Current LED driver instead. This solution suits for professional lighting applications or anyone who simply wants a better lighting effect for his or her applications.
In this video, we use the SORAA Constant Current LED MR16 bulb ( SORAA Model # SM16C-CC1-36D-927-03 ) & a HEP 10W Dimmable Constant Current LED Driver to compare its performance with a 12Vac ELV approach side-by-side. Given the SORAA bulb has a typical operating voltage of 28V and it’s capable of driving at 350mA (MAX), we use a 10W model from HEP to drive the bulb ( HEP Model # LMTC10W350-Z ) to drive the bulb.
With this combination, we can maximize the lumen output (10W vs. 7W of the typical 12Vac LED MR16) and maintain the typical 1:1 connection (one driver, one bulb) for standard MR16 installation. Furthermore, the Live-in/Live-out wiring from the AC Mains to Phase Dimmer (DZ3G450DIAL) and from the Phase Dimmer to the live inputs to the 12Vac Transformer or the LED Drivers remain the same. Another reason why this particular Constant Current LED driver is selected is that of its similar size to the 12Vac ELV transformer.
The difference between the two approaches is that the 12Vac ELV approach would require a Dimmable LED MR16 bulb, while the Constant Current approach would require a Dimmable Constant Current LED Driver instead.
Since both bulbs have different specifications, our intention is to introduce the dimmable Constant Current LED MR16 solution and to demonstrate the lighting effects when both approaches are connected to the same phase dimmer, DZ3G450DIAL. The contrast between the two approaches is obvious and thus, for professional applications, such as Retail Lighting applications, where High CRI performance is a critical design element, it’s suggested to consider the use of Constant Current LED MR16 instead.
