Light Bulbs

Smart bulbs are the most popular entry point into smart home lighting, and for good reason -- you screw one in, connect the app, and you've got voice control and scheduling in five minutes. But there are real differences between a $10 bulb and a $50 one, and picking the wrong type can mean a lot of returns.

First, check your socket type. Most smart bulbs are A19 with an E26 base -- your standard household bulb. Recessed lights usually need a BR30. Candelabra fixtures use E12 bases, and the smart bulb selection there is much smaller. Know your socket before you shop.

White-only vs. color is a real choice. Color bulbs cost roughly twice as much as tunable white. Be honest about whether you'll actually use color. A tunable white bulb that shifts between warm (2700K) and daylight (5000K) handles 95% of what most people need. Save color bulbs for accent lamps or media rooms.

Brightness matters -- check the lumens. Many smart bulbs top out at 800 lumens (60W equivalent). Fine for a table lamp, weak for a room's main fixture. If you need real output, look for 1100+ lumen bulbs (75W equivalent) or higher.

Protocol picks:

• WiFi bulbs (Wyze, Kasa, LIFX) -- no hub needed, but each one sits on your network. A dozen of these and your router might struggle.
• Zigbee bulbs (Philips Hue, IKEA Tradfri, Sengled) -- need a hub, but they mesh with each other and don't touch your WiFi. Best for whole-home setups.
• Thread/Matter bulbs (Nanoleaf Essentials, Eve) -- mesh networking without a proprietary hub. Smaller selection but growing fast.

The dimmer problem. If your smart bulbs are on a circuit with a traditional dimmer switch, you'll get flickering, buzzing, or bulbs that won't turn off completely. Smart bulbs need a regular on/off switch or a compatible smart switch.

One more thing: smart bulbs stop being smart when someone flips the wall switch off. If others in your house do this out of habit, you'll end up with "dumb" smart bulbs half the time. That's why many people switch to smart dimmers instead -- but if you want color, bulbs are your only option.
