Light bulbs in our range include standard LED bulbs and smart bulbs for homes, offices and shops that want to replace old lamps or control lighting from a phone. Brands include SYNERGY21, OSRAM, Philips Hue and TP-Link. Over 190 products are listed, from plain white bulbs to colour-changing smart models.
How to choose light bulbs
Bulb base. Check the fitting on your old bulb before anything else. The most common are E27 (large screw), E14 (small screw), B22 (bayonet) and GU10 (two-pin spotlight), and a bulb with the wrong base will not fit the holder.
Brightness and colour temperature. Brightness is measured in lumens, not watts. A bulb of around 800 lumens replaces an old 60 W incandescent. Warm white, about 2700 K, suits living rooms and bedrooms, while neutral or cool white works better in kitchens, workshops and offices.
Smart features. A basic LED bulb simply switches on and off, whereas a smart bulb can be dimmed, scheduled and controlled from an app or by voice. Some smart bulbs change between warm and cool white, and others produce full colour. If you only want good everyday light, a white bulb is cheaper to run and simpler to set up.
Connection type. Smart bulbs connect over Wi-Fi, Bluetooth or Zigbee. Wi-Fi bulbs connect directly to your router, Bluetooth suits a few bulbs in one room, and Zigbee bulbs normally need a bridge or hub but cope better with larger setups. Check that the bulb works with the voice assistant or smart home platform you already use.
Dimming. Smart bulbs dim through the app or a remote. Standard LED bulbs only dim if they are marked as dimmable and are paired with a compatible dimmer switch, otherwise they may flicker or buzz.

Light bulbs FAQ
What is the difference between a smart bulb and an LED bulb?
A smart bulb is an LED bulb with built-in wireless connectivity. It can be dimmed, scheduled and controlled from a phone or by voice, and some models change colour. A standard LED bulb uses the same type of light source but only works with a wall switch.
Do smart bulbs need a hub?
It depends on the connection type. Wi-Fi and Bluetooth bulbs usually work without a hub, while Zigbee bulbs such as those in the Philips Hue and Aqara systems normally need a bridge or hub. A hub makes larger setups more stable and allows more devices to work together.
How many lumens do I need?
Around 800 lumens replaces an old 60 W incandescent bulb and is enough for most general room lighting. Lower values of 300 to 500 lumens suit bedside lamps and accent lighting. Task areas such as kitchens and desks benefit from brighter bulbs.
Which bulb base do I need?
The base must match the holder in your light fitting. Look at your old bulb or the fitting itself: E27 and E14 are screw bases, B22 is a bayonet twist fitting, and GU10 is a two-pin spotlight base. The code is usually printed on the old bulb or its packaging.
