Description

The Energizer Smart LED is a 4.8W GU10 bulb offering variable white temperature control from warm to cool tones plus a full RGB colour palette, controlled via smartphone app or voice assistant. The bulb delivers 345 lumens in white mode and supports group control, allowing multiple bulbs to be synchronised across a room or zone without requiring a separate hub.

Designed for downlights, track lighting and spotlights in kitchens, living rooms and bedrooms, the bulb connects directly to 2.4GHz Wi-Fi and integrates with Alexa, Google Home and Siri Shortcuts for voice control and scheduling. Variable white temperature allows the bulb to shift from warm 2700K tones for evening relaxation to cooler 6500K daylight tones for task lighting, while colour modes enable accent lighting or mood scenes.

The 4.8W LED replaces a traditional 50W halogen GU10, reducing power consumption by over 90% while maintaining comparable light output in white mode. Dimming is controlled entirely via the app or voice command rather than a physical wall dimmer, with brightness adjustable from 1% to 100%. The bulb fits standard GU10 twist-lock sockets and operates on 230V mains, rated for use in Zone 3 bathrooms (outside shower enclosures).

Frequently Asked

Does this need a smart hub?

No. The bulb connects directly to 2.4GHz Wi-Fi and is controlled via the Energizer app on iOS or Android. It integrates with Alexa, Google Home and Siri Shortcuts without requiring a separate bridge or hub.

Can it be used with a standard wall dimmer switch?

The bulb is app-dimmable only and should be installed on a standard on/off switch circuit. Using a physical wall dimmer can cause flickering or compatibility issues. Dimming is controlled entirely through the app or voice commands.

What's the colour temperature range in white mode?

The bulb offers variable white temperature, typically spanning warm 2700K tones through to cool 6500K daylight. Exact range depends on firmware version. RGB colour modes are separate from the white temperature control.

Can multiple bulbs be controlled together?

Yes. The app supports group control, allowing you to create lighting zones where multiple bulbs change colour, temperature or brightness simultaneously. This is useful for multi-bulb downlight setups in kitchens or living rooms.
