Smart bulbs promise lights you can dim from your phone, switch on with your voice and set on a schedule. They also cost more than ordinary LED bulbs, so it is fair to ask: are smart bulbs worth it, or just a fun gadget?

The answer depends on how you use your lights. Below are the real running costs, the benefits that matter day to day, and the cases where a plain LED is the better buy.
Are smart bulbs worth it: the short answer
For rooms where you want schedules, dimming or remote control, yes. Smart bulbs are LEDs, and the US Department of Energy says LED bulbs use at least 75 percent less energy than incandescent bulbs and can last up to 25 times longer. The catch is a small standby draw: a smart bulb stays connected even when it is off. The Philips Hue A19 bulb, for example, is rated at 7.5 watts on and 0.5 watts in standby.
How smart bulbs work
A smart bulb has a tiny radio inside. It connects to your phone or a hub using Wi-Fi, Bluetooth, Zigbee or Thread, and listens for commands even when the light is off. That is what lets you control it from an app, a voice assistant or a schedule. It only works if the wall switch stays on, because flipping the switch cuts the bulb’s power completely.
What a bulb costs to run for a year
This table compares one bulb used 3 hours a day at the 2026 US average price of 18.2 cents per kWh. The smart bulb figure includes 0.5 watts of standby power for the other 21 hours.
| Bulb type | Power when on | Energy per year | Cost per year |
|---|---|---|---|
| Incandescent (60W) | 60 watts | about 65.7 kWh | about $11.96 |
| Basic LED (60W equivalent) | 7.5 watts | about 8.2 kWh | about $1.49 |
| Smart LED (60W equivalent) | 7.5 watts + 0.5W standby | about 12.0 kWh | about $2.19 |
6 easy ways smart bulbs can pay off
- Schedules. Lights turn off by themselves at bedtime, so nothing burns all night by mistake.
- Away mode. Lights can turn on and off while you travel, so the home looks lived in.
- Dimming without rewiring. You get dimmable light in any lamp without changing the wall switch.
- Gentle wake-up. A slow sunrise effect in the morning is easier on the eyes than a sudden bright light.
- One-tap scenes. Turn off every light in the house from bed with a single tap.
- Fewer trips to the switch. Helpful for older family members or anyone with limited mobility.
When smart bulbs are not worth it
If a light is mostly controlled by a wall switch that people flip off, a smart bulb loses its main benefits. In closets, garages and hallways you rarely think about, a basic LED or a motion sensor light is cheaper and simpler. Some homes are better served by one smart switch than by several smart bulbs in the same fixture.
Quick FAQ
Do smart bulbs use electricity when they are off? A little. Most draw well under a watt in standby, which adds up to well under a dollar a year per bulb at average prices.
Do I need a hub? Not always. Many Wi-Fi and Bluetooth bulbs work straight from an app. Zigbee and Thread bulbs need a hub or a compatible smart speaker.
Are smart bulbs worth it for renters? Often, yes. They screw into existing fittings, need no wiring and can move with you.
Are smart bulbs worth it: a quick recap
- Energy: they are LEDs, so they use far less power than old bulbs.
- Standby: about 0.5 watts, or roughly 80 cents a year per bulb.
- Best for: lamps and rooms where schedules and dimming help.
- Skip them: where a wall switch is flipped off all the time.
Final thoughts
So, are smart bulbs worth it? For a few key lamps, usually yes, and the extra running cost is small. Start with one room, see how you use it, then add more. If you would rather control lamps you already own, our guide to smart plugs shows another simple option.
