Pulsed dimming is a lighting control technique that adjusts brightness by rapidly turning lights on and off at a frequency undetectable to the human eye. This method provides smooth dimming, energy efficiency, and compatibility with various lighting types, making it a popular choice in modern smart home systems like those offered by Repenic.

Pulsed dimming modulates light intensity by switching the light source on and off in rapid pulses, controlling the effective power delivered. This pulse-width modulation adjusts brightness without changing voltage, resulting in stable light output and less flicker compared to analog dimming methods. It is especially effective for incandescent, halogen, and certain LED lights.
This technique uses a duty cycle — the ratio of on-time to total cycle time — to determine brightness. For example, a 50% duty cycle means the light is on half the time and off half the time at a very high frequency, imperceptible to the eye. This reduces wear on the light source, conserves energy, and extends bulb life. Systems like Repenic’s Zigbee dimmer switches employ such methods for smooth performance without needing a neutral wire.
Pulsed dimming offers several benefits:
Energy efficiency by reducing power consumption without compromising brightness quality.
Compatibility with many dimmable light types, including LEDs and halogen bulbs.
Reduced flicker compared to traditional dimming, enhancing eye comfort.
Longer bulb lifespan due to controlled electrical pulses instead of continuous voltage drops.
Integration with smart home systems, allowing remote control and automation.
Repenic’s Zigbee dimmer switches allow homeowners to achieve smooth dimming without complex wiring setups, thanks to their no-neutral wire design and support for common dimmable lighting types.
Pulsed dimming works well with:
Incandescent bulbs
Halogen lamps
Dimmable LED lights
It is not compatible with CFL or fluorescent lights because of their electrical characteristics and is unsuitable for smart bulbs that use internal digital controls.
| Lighting Type | Compatible with Pulsed Dimming? | Notes |
|---|---|---|
| Incandescent | Yes | Supports smooth dimming |
| Halogen | Yes | Excellent dimming response |
| Dimmable LED | Yes | Compatible with Repenic switches |
| CFL | No | Not compatible |
| Fluorescent | No | Not compatible |
| Smart Bulbs | No | Requires own app control |
Repenic’s Zigbee dimmer switches align with this compatibility, focusing on dimmable LED and halogen lights and excluding smart bulb control.
Pulsed dimming provides:
Minimal flicker, eliminating discomfort common in some analog systems.
Better energy efficiency by controlling power electronically without resistive losses.
Compatibility with wireless smart home systems for remote and automated control.
Simpler hardware needs, improving reliability since supply voltage remains constant.
These benefits make pulsed dimming ideal for devices such as Repenic’s Zigbee dimmer switches, which deliver refined lighting control without complex installation.
Yes, pulsed dimming is often controlled through wireless protocols including Zigbee. Zigbee-enabled dimmer switches modulate light output by pulsed dimming, letting users adjust brightness remotely, create scenes, and schedule lighting via smartphones or home automation hubs.
Repenic’s Zigbee dimmer switches offer:
Over 30 meters indoor communication range for stable control.
Compatibility with most UK homes through no-neutral wire design.
A variety of attractive faceplate finishes to suit modern interiors.
This integration improves convenience and user experience by combining advanced pulsed dimming with wireless control.
By rapidly switching power on and off, pulsed dimming reduces total energy delivered without compromising light quality. This lowers electricity use and environmental impact. Also, pulsed dimming prevents overheating and electrical stress on filaments or LED drivers, which extends bulb life.
| Parameter | Traditional Dimming | Pulsed Dimming |
|---|---|---|
| Energy Consumption | 100% | 60–80% (variable) |
| Average Bulb Lifespan | Standard | 20–30% longer |
| Flicker Level | Medium to High | Minimal |
