How Much Does It Cost to Run a LED Light Bulb in India? (2026)
An LED bulb producing the same light as an old 60 watt incandescent uses about 9 watts. Lighting has gone from a major electricity cost to a minor one in homes that have switched fully to LED.
A typical led light 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 (15 W) | ₹0.090 | ₹0.45 | ₹13.50 | ₹164.25 |
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 led light 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 led light bulb
- Replace any remaining incandescent or halogen bulbs. The payback is usually under a year.
- Choose lumens for brightness, not watts.
- Smart bulbs draw about half a watt in standby waiting for commands.
- Use task lighting instead of lighting a whole room.
