A practical first-timer's guide, so you pick the right bulb the first time.
Match the base type (E27, B22, E14) to your lamp before buying. Most bulb returns happen over wrong fittings.
Warm white (~2700K) suits living rooms; cool white suits desks and kitchens. Dimmable bulbs give you both moods.
Forget watts — lumens measure brightness. Around 800 lumens replaces an old 60W bulb.
Wi-Fi bulbs work alone but crowd your network. Hub-based systems stay more reliable when you own many bulbs.
Make sure the bulb works with your phone and any voice assistant you already use, before checkout.
Smart bulbs sip power even when "off". It is small per bulb, but worth knowing across a whole house.
Try a single bulb in your most-used lamp first. Then buy the rest of the set with confidence.
Smart bulbs need constant power. If someone flips the wall switch, the smart features stop working.
