As of 13 August 2026, AI can choose smart bulbs for your UK light fittings.
This still needs a person who signs their name to it.

If this goes wrong: you buy a bulb with the wrong cap, size, brightness or smart-home connection and return or replace it.

How to actually do it
- Turn off the light and remove the existing bulb only if it is safe to do so, then photograph the bulb markings, cap, shape and the available space inside the fitting.
- Open the fitting or bulb manufacturer instructions if you have them and record the cap type, maximum bulb dimensions, voltage, wattage limit, dimmer status and whether the fitting is enclosed or used outdoors.
- Write down the smart-home system you use, such as a hub or voice assistant, plus whether you need white tuning, colour control, dimming, schedules or operation without a hub.
- Paste those details and the copyable prompt into a chatbot, including links or copied specifications for any bulbs you are already considering.
- Ask the chatbot to separate confirmed compatibility from assumptions and to produce a shortlist with the exact cap, dimensions, electrical and smart-home checks for each bulb.
- Open each manufacturer's UK product page and compare its cap, dimensions, voltage, fitting restrictions, dimmer guidance and connection requirements with your notes before buying.
Prompt
Help me choose smart bulbs for my UK light fittings. Use only the information I provide and do not guess compatibility. First identify any missing details I must check, especially the cap type, bulb shape, maximum bulb size, voltage, dimmer compatibility and whether the fitting is enclosed. Ask clarification questions if needed. My details: - Number of bulbs and room or fitting: [insert] - Markings on the existing bulb or fitting: [insert] - Cap type, if known: [insert] - Bulb shape and maximum dimensions: [insert] - Existing dimmer, switch or sensor: [insert] - Smart-home system, hub or voice assistant: [insert] - Wi-Fi or other connection requirements: [insert] - Desired brightness, colour temperature and colour-changing features: [insert] - Need for outdoor, bathroom, enclosed-fitting or high-temperature use: [insert] - Budget and UK retailers I am willing to use: [insert] Give me a shortlist with the exact compatibility points to verify for each option. Separate confirmed facts from assumptions. Do not advise me to alter mains wiring or bypass a safety feature. Tell me what to check on the manufacturer product page and packaging before buying, and reject any option where the fitting or electrical details are uncertain.

What it gets wrong
- Cannot reliably identify a cap type, fitting depth or enclosure restriction from a poor photograph.
- Cannot know whether a bulb will physically fit unless you provide accurate measurements and compare them with the product specification.
- Cannot guarantee that a manufacturer's current app, hub or voice-assistant support has not changed.
- Cannot test wireless signal, switch behaviour, brightness or heat in your room.
- Cannot safely resolve uncertain mains wiring or advise you to modify the fitting.
Even on a YES, the friction has a name: context depth, judgement under ambiguity and verification cost.
How we scored this
Five axes, each scored nought to two by hand: ten means AI carries the task cleanly, and the thresholds that turn a total into YES, PARTLY or NO are published in the methodology. Each axis name links to its definition.

FAQ
- Can AI tell me which smart bulb fits my lamp?
- Yes, if you provide the cap type, bulb dimensions, fitting restrictions and smart-home system. Check the recommendation against the manufacturer's UK specifications before buying.
- Can ChatGPT identify a light bulb fitting from a photo?
- It can suggest a likely fitting from a clear photo, but a photo is not proof of compatibility. Read the markings on the existing bulb or fitting and measure the available space.
- Do smart bulbs work with UK dimmer switches?
- Some smart bulbs support dimming through their app or compatible control system, while an existing wall dimmer can cause compatibility problems. Give the chatbot the exact dimmer and bulb models, then follow the bulb manufacturer's guidance.
- Can AI choose smart bulbs that work with Alexa or Google Home?
- It can filter a shortlist by the assistant and connection method you use. Confirm the exact model's current compatibility on the manufacturer's product page because support can differ between otherwise similar bulbs.
