How Much Does It Cost to Run a Smart LED Bulb in India? (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 ₹0.054 per hour, or about ₹8.10 per month at 5 hours a day in India. Cheap to run
| Wattage | Per hour | Per day | Per month | Per year |
|---|---|---|---|---|
| Low (5 W) | ₹0.030 | ₹0.15 | ₹4.50 | ₹54.75 |
| Typical (9 W) | ₹0.054 | ₹0.27 | ₹8.10 | ₹98.55 |
| High (14 W) | ₹0.084 | ₹0.42 | ₹12.60 | ₹153.30 |
Formula: watts ÷ 1000 × hours × price per kWh. Typical use is 5 h/day ≈ 16 kWh per year.
In India, with electricity at ₹6.00 per kWh (source: Typical urban domestic slab rate; national average ≈ ₹5.5/unit FY2025-26, 2026-04), a typical smart led bulb costs ₹0.054 per hour and about ₹98.55 per year at 5 hours a day. Each ₹1.00 of electricity buys roughly 18.5 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 (₹26.28) 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.
