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.

Dimmable LED MR16 with 12V Magnetic Transformer Backward Compatibility (MLV)Using dimmable LED MR16 bulbs to replace the Halogen bulbs is definitely a good energy saving practice to reduce the energy wastage. However, some installers might have bad experience with the replacement due to the varying performance of LED MR16 bulbs with the transformers already installed.
When using dimmable LED MR16 bulbs for Halogen replacement, several considerations must be aware before project implementation. First of all, Halogen bulbs are designed to operate at very hot temperature without degradation in performance, whereas LED are sensitive to heat and thus, heat dissipation for the LEDs must be done properly. Furthermore, the LED MR16 bulbs are required to work with the 12V transformers originally designed for Halogen bulbs that pose a much higher minimum power requirement for LEDs and require a resistive load to complete the circuit (LEDs are non-resistive).
In this application, the 12V transformers are further classified into magnetic (MLV) and electronic (ELV), which operate by different principles. Due to the size and weight difference, the MLV transformer is less common than ELV transformer in the market today. However, as the MLV transformer’s working principle is easy to understand that it only produces a low-frequency step-down waveform from the mains voltage, so the dimming performance of a few dimmable LED MR16 bulbs using the MLV transformer is used as the baseline for our comparison when changing to some commonly available 12V electronic transformers in another video. In this video, we would select a few dimmable LED MR16 bulbs to connect with a magnetic transformer to show how the individual bulbs perform.
This difference in performance leads to the "Backward Compatibility of the LED MR16 Bulbs" topic, which presents a technical challenge to the LED driver IC manufacturers. Without a proper understanding of the issue, installers may run into mysterious flickering issues with their LED MR16 bulbs when installers only expect a drop-in replacement for the Halogen.
At the end of the video, we’ve concluded several key points:
- Size and weight difference of the MLV and the ELV transformers
- Acoustic noise and dimming performance difference with the TRIAC and the Digital LED Dimmers
- All the few dimmable LED MR16 bulbs we used in this video give reasonable dimming performance with the 12V MLV transformer
