A wall-mounted dimmer switch designed for smooth, flicker-free control and straightforward retrofit installation. Gentle light transitions help make evenings more comfortable and calm for anyone sensitive to sudden brightness changes. Is the iolloi LED Dimmer Switch the simple upgrade needed for modern LED lighting?
⚡ At a Glance
- • Dimming Performance: Silent, smooth fades with a full 0 to 100% dimming range for compatible bulbs
- • Best for: Homeowners upgrading to dimmable LEDs who need reliable, retrofit-friendly controls
- • Not ideal for: Setups that require app control, smart home integration or multi-zone automation
Trailing-edge 1-gang 2-way control produces consistent LED dimming across the full range. Compatible with both dimmable LED bulbs and traditional incandescent or halogen lamps.
Quiet, smooth lighting transitions, thanks to trailing-edge dimming and soft-start
Trailing-edge electronics and a soft-start routine gradually ramp output to lamps, reducing inrush current and suppressing audible buzzing. The control handles the lower loads typical of modern LEDs while delivering steady fades on and off.
Flicker-free fades protect the eyes during on/off cycles and create calm, usable light levels. User feedback highlights quiet operation and stable dimming with a range of LED bulbs.
Easy retrofit installation, with no neutral required
Designed to work with existing wiring that lacks a neutral conductor and fits into wall boxes with at least 25 mm depth. A combined push on/off and rotary control supports 1-gang 2-way installations.
Many older UK homes can be upgraded without additional wiring changes, making the swap straightforward for DIYers or electricians. Adjustable minimum dim level helps match different lamp types during setup.
Broad bulb compatibility and energy-saving dimming, with clear load limits
Rated for dimmable LED bulbs from 3 W minimum to 100 W maximum, and for incandescent or halogen loads up to 150 W. The control provides a uniform 0 to 100% dimming range to reduce lamp stress and lower power draw at reduced brightness.
Suitable for most domestic LED and traditional bulbs within the specified wattage ranges, while supporting reduced energy use when lights run at lower levels. Clear load limits make it easier to plan multi-lamp circuits safely.
