Ajax LightCore (Dimmer) Smart Dimming Core for Adjustable Lighting | 91248.255.WH1 –

The Ajax LightCore (Dimmer) Jeweller is the electronic dimming core of an Ajax LightSwitch, designed for switching compatible lighting on and off while also providing smooth brightness adjustment. Pair it with a SoloButton (Dimmer) to create a complete touch-sensitive dimmer with local control at the wall and smart control through an Ajax system.

The no-neutral design makes it particularly useful for retrofit installations where a neutral conductor is not available at the switch position. The LightCore uses the European type 55 mounting format, so installation into a standard South African 100 × 50 mm / 4 × 2 wall box requires the IoT 4 × 2 Wall Box Installation Adapter.

Complete Your Switch

The LightCore is the dimming core only. The following components complete a typical standalone dimmer installation:

If you already have a compatible SoloButton (Dimmer) and suitable type 55 mounting arrangement, the LightCore can be purchased on its own. Otherwise, choose the required touch panel and wall-box adapter using the Product Add-ons on this page.

How It Works

The LightCore connects to the power phase and the lighting load without requiring a neutral conductor. A SoloButton (Dimmer) attaches to the core and provides the touch-sensitive control surface and integrated dimming slider.

Brightness can be adjusted from the wall or through Ajax apps when the switch is connected to a compatible Ajax hub. The selected brightness level is remembered and restored the next time the lighting is switched on.

The completed LightSwitch can also operate locally without being added to an Ajax hub. Connecting it to an Ajax system adds remote control, schedules, timers and automation scenarios.

Why Choose This Product?

• Smart dimming without a neutral: suitable for many retrofit installations where only the live phase is available at the existing switch position.
• Smooth brightness control: adjust compatible lighting using the SoloButton dimming slider or remotely through Ajax apps.
• Brightness memory: the switch remembers the selected level and restores it when the light is switched on again.
• Smart and local control: use the completed dimmer normally at the wall or add app control through a compatible Ajax hub.
• Automation ready: lighting can respond to schedules, security mode changes and other supported Ajax automation events.
• Built-in protection: current and temperature protection can disconnect the lighting load when operating limits are exceeded.
• Modular finish: choose a Black or White SoloButton (Dimmer) separately without changing the concealed LightCore.

Before You Buy

• This product is the LightCore (Dimmer) electronic core only. A compatible Ajax SoloButton (Dimmer) touch panel is required to complete a standalone dimmer switch.
• For installation into a standard South African 100 × 50 mm / 4 × 2 wall box, add the IoT 4 × 2 Wall Box Installation Adapter.
• Supported loads are 8–150 VA for dimmable LED and incandescent lighting, and 20–150 VA for halogen lighting.
• Conventional fluorescent lamps, compact fluorescent lamps and smart lamps with built-in control electronics are not supported.
• Use one supported lighting type on the dimmer; simultaneous operation with mixed lamp types is not supported.
• If a compatible lamp flickers or the dimmer does not operate correctly, an Ajax Bypass (Dimmer) [55] may be required and is sold separately.
• A compatible Ajax hub is required for remote app control and automation, but local switching and dimming can operate without a hub once the LightSwitch is correctly assembled.
• The LightCore is rated IP20 and is intended for indoor installation.
• Installation must be carried out by a suitably qualified electrician or installer.
