How Much Does It Cost to Run a Smart LED Bulb in Canada? (2026)
Smart bulbs draw the same as ordinary LEDs when lit, plus about half a watt around the clock to stay connected. Across a house full of them, that standby draw can exceed the lighting itself.
A typical smart led bulb (9 W) costs C$0.001 per hour, or about C$0.19 per month at 5 hours a day in Canada (average). Cheap to run
| Wattage | Per hour | Per day | Per month | Per year |
|---|---|---|---|---|
| Low (5 W) | C$0.001 | C$0.004 | C$0.11 | C$1.28 |
| Typical (9 W) | C$0.001 | C$0.006 | C$0.19 | C$2.30 |
| High (14 W) | C$0.002 | C$0.010 | C$0.29 | C$3.58 |
Formula: watts ÷ 1000 × hours × price per kWh. Typical use is 5 h/day ≈ 16 kWh per year.
In Canada, with electricity at C$0.14 per kWh (source: Canada Energy Regulator 2026 market snapshot, 2026-06), a typical smart led bulb costs C$0.001 per hour and about C$2.30 per year at 5 hours a day. Each C$1.00 of electricity buys roughly 793.7 hours of use.
How to lower the cost of running a smart led bulb
- Group bulbs on smart switches instead of individual smart bulbs where a whole room switches together.
- Use schedules and dimming. A bulb at 50 percent brightness uses roughly half the power.
- Count your bulbs. Thirty smart bulbs at 0.5 watts standby is 130 kWh a year.
In standby it draws about 0.5 W, which adds roughly 4 kWh (C$0.61) per year if it is never unplugged.
Frequently asked questions
Do smart bulbs use electricity when off?
Yes, about 0.3 to 0.5 watts each, roughly 3 to 4 kWh per bulb per year.
Are smart bulbs more expensive to run than normal LEDs?
Slightly, because of standby draw. Dimming and scheduling can more than offset it.
Do color-changing bulbs use more power?
Bright white uses the most. Saturated colours often draw less because fewer LEDs are lit.
