Dimmable LED lights flicker at night mostly because of incompatibility with dimmer switches, voltage fluctuations, or faulty wiring. To stop flickering, use LED-compatible dimmers such as Repenic Zigbee Dimmer Switches, ensure wiring is secure, and avoid mixing incompatible bulbs. Proper installation and quality components lead to stable, flicker-free lighting.
Flickering often results from using dimmer switches not designed for LEDs, voltage instability, or loose electrical connections. LEDs require dimmers built for low wattage electronic loads, and standard dimmers for incandescent bulbs usually cannot regulate LED current properly. Flickering is worse with poor wiring or low-quality bulbs and tends to appear at lower brightness.
Using a dimmer switch compatible with LED technology, like Repenic Zigbee Dimmer Switches, minimizes flickering. These dimmers support dimmable LED loads and do not require a neutral wire, fitting most UK homes. Their Zigbee communication ensures stable control without flicker, unlike older dimmers designed for incandescent bulbs.
| Feature | Repenic Zigbee Dimmer Switch | Standard Incandescent Dimmer |
|---|---|---|
| Requires Neutral Wire | No | Often Yes |
| Compatible with Dimmable LEDs | Yes | Usually No |
| Communication Range | Over 30 meters Zigbee | None |
| Suitable for CFL/Fluorescent | No | No |
| Faceplate Finish Options | Black, White, Stainless Steel, Brass | Limited |
Flickering is more noticeable at night because dimmers operate at lower brightness, pushing LED drivers near their minimum thresholds. At low power, voltage fluctuations and electrical noise have a stronger impact, causing intermittent flickers. Some older or low-quality bulbs lack stable drivers suited for dimming.
Inspect wiring for loose connections or damaged cables, which cause inconsistent power flow and flickering. Ensure all wiring terminals at switches and light fixtures are tight and secure. Avoid mixing different bulb types on the same circuit. If unsure, consult a qualified electrician for a professional assessment.
Use only bulbs labeled “dimmable LED” from trusted brands and verify compatibility with your dimmer model. Avoid CFLs, fluorescent, or non-dimmable LEDs as they tend to flicker. Quality LEDs feature advanced driver circuits for smooth dimming performance.
Upgrade your dimmer switch if flickering persists despite using compatible bulbs and checking wiring. Modern LED-compatible dimmers like Repenic’s Zigbee Dimmer Switches provide stable dimming, require no neutral wires, and improve energy efficiency while enhancing smart home integration.

Electromagnetic interference from routers, motors, or other devices can cause flickering in sensitive LEDs. Temperature extremes also affect LED driver circuits, sometimes causing intermittent flickers during night hours.
Yes, simple DIY fixes include replacing incompatible dimmers, tightening connections, using only dimmable LED bulbs, and cleaning switch contacts. For complicated electrical problems or persistent flickering, professional electrician help is advisable for safety.
Stopping dimmable LED lights from flickering at night involves using compatible dimmers like Repenic Zigbee Dimmer Switches, selecting quality dimmable LED bulbs, and ensuring secure wiring connections. Flickering mostly results from mismatched components or electrical faults but can be resolved by upgrading dimmers and bulbs while following safe installation practices. These steps create comfortable, flicker-free lighting that enhances your home’s night ambiance.
Q1: Can flickering LED lights damage dimmer switches?
No, flickering indicates compatibility or wiring issues and does not harm dimmer switches.
Q2: Does Repenic support smart bulbs?
No, Repenic Zigbee dimmers are incompatible with smart bulbs.
Q3: Why don’t CFL bulbs work with Repenic dimmers?
CFL bulbs have different drivers incompatible with Repenic dimmers made for LEDs and incandescent lamps.
Q4: What is the recommended distance between Repenic Zigbee dimmers and LED fixtures?
Zigbee communication covers over 30 meters indoors, but wiring distances must comply with electrical codes.
Q5: Do Repenic thermostats affect LED flickering in lighting?
No, Repenic thermostats control heating systems and have no impact on lighting flicker.
