Best OverallPros
- Excellent colour range and brightness
- Reliable app with scheduling
- Dual connectivity options
Cons
- Requires hub for Zigbee
- Slightly larger than standard bulbs
The Knightsbridge Smart+ A60 RGBW is the most versatile bulb in the range. With 806 lumens and a wide colour temperature range, it suits both task lighting and ambient moods. Owner reviews consistently highlight the smooth dimming and accurate colour reproduction compared to cheaper alternatives.
Setup is straightforward via the Knightsbridge app, and the dual Wi-Fi/Zigbee support gives flexibility for different smart home setups. Some users note the bulb is a bit long for some lamp shades, but performance is top-notch for the price.
Knightsbridge Smart+ GU10 Dimmable
Best Budget SpotlightPros
- Very affordable per bulb
- Works with most Zigbee hubs
- Smooth dimming down to 10%
Cons
- Warm white only, no RGB
- Requires hub for operation
For kitchens and hallways with GU10 fittings, this bulb offers reliable dimming at a low cost. It produces a consistent warm white light that works well with existing dimmer switches when paired with a compatible hub.
Owner feedback praises the build quality and lack of flicker at low levels. The main limitation is the lack of colour options, but for functional lighting it is a solid choice.
Knightsbridge Smart+ Filament Edison
Best DecorativePros
- Vintage Edison design
- Warm dimming effect
- No hub required
Cons
- Lower brightness than standard bulbs
- Limited to warm white tones
This filament-style bulb is designed for exposed fittings in restaurants or living rooms. The visible LED filaments mimic traditional Edison bulbs while offering smart control via Wi-Fi.
Users appreciate the aesthetic and the ability to dim and schedule without extra hardware. Brightness is adequate for ambiance but not for task lighting. It is a niche product that excels in its role.
Knightsbridge Smart+ B22 Bayonet
Best Standard FittingPros
- Standard B22 fitting
- Bright and tunable white
- Reliable Zigbee connection
Cons
- No RGB colour
- Hub needed for full features
This bayonet cap bulb is ideal for UK homes with B22 fittings. It delivers the same 806 lumens as the A60 but in a form factor that fits standard ceiling roses and lamps without adapters.
It offers tunable white from warm to cool, making it suitable for living rooms and offices. Reviews note the build quality is solid and the Zigbee connection is stable. The lack of colour is the only drawback for those wanting RGB effects.
Knightsbridge Smart+ Outdoor PAR38
Best OutdoorPros
- Weather-resistant design
- Very bright for outdoor use
- No hub required
Cons
- Higher power consumption
- Limited to tunable white
Designed for outdoor floodlights and security fittings, this PAR38 bulb is IP65 rated and built to withstand the elements. It produces 1200 lumens, making it one of the brightest Knightsbridge smart bulbs.
Wi-Fi connectivity means it works directly with the app for scheduling and remote control. Some owners report the app can be slow to respond outdoors due to signal range, but overall it is a capable outdoor smart light.
What to check before buying a Knightsbridge smart bulb
First, confirm your existing light fitting type. Knightsbridge offers bulbs in B22, E27, GU10, and PAR38 bases. Using the wrong base requires an adapter, which can affect fit and safety.
Next, consider your smart home ecosystem. Some Knightsbridge bulbs use Wi-Fi and work without a hub, while others rely on Zigbee and need a compatible hub like those from Philips Hue or Amazon Echo. Check the bulb specifications to ensure compatibility with your setup.
Finally, look at the lumen output and colour temperature range. For living areas, a bulb with tunable white (2700K-6500K) offers flexibility. For outdoor use, prioritise higher lumens and an IP65 rating for weather resistance.
Mistakes to avoid when choosing smart bulbs
Do not assume all smart bulbs work with your existing dimmer switches. Knightsbridge smart bulbs are designed to be controlled via app or voice, and using them with a physical dimmer can cause flickering or damage. Always use the app for dimming.
Avoid buying bulbs with features you will not use. If you only need warm white, paying extra for RGB colour is unnecessary. Focus on the specific needs of each room to get the best value.
Do not ignore the hub requirement. Some Knightsbridge bulbs require a Zigbee hub for full functionality. If you do not have one, choose the Wi-Fi versions to avoid disappointment.
