How many units (kWh) does a led bulb use per month?

Running 6 hours a day at 9 W, a led bulb consumes about 2 units per month — that's 0.1 units per day.

How much does it cost per month on the 200-unit slab?

On the Unprotected 101–200 unit slab (Rs. 22.95/unit) the energy charge alone is about Rs. 37. Add ~Rs. 5 for FPA + QTA and 18% GST on top.

Is a led bulb cheaper to run on protected tariff?

Yes — at Rs. 11.69/unit (protected slab 1–100 units) the same 2 units cost only Rs. 19, roughly half. But qualifying requires staying under 200 units total for 6 months, which is hard when this appliance alone uses 2 units.

Does running it during off-peak hours save money?

Only if you have a Time-of-Use (TOU) meter — typically 3-phase domestic, commercial A-2 or industrial B-2. On a flat single-phase domestic meter the tariff is the same 24 hours. See your DISCO's peak-hours page for exact windows.

Will solar make this appliance free to run?

Solar cuts the daytime portion of this load to nearly zero. Under the 2026 net-billing regime, exported units are worth Rs. 11–13 vs Rs. 27–42 for units you self-consume — so timing the appliance to run in daylight matters far more than it did on old net-metering.

LED bulb electricity cost in Pakistan (2026)

A 9-W LED bulb replaces a 60-W incandescent and gives the same light. A single bulb on 6 hours a day costs Rs. 20–75 per year — negligible on any Pakistani slab, but multiply by 15 bulbs and the whole house lighting is Rs. 300–1,100 per year.

How much energy does a led bulb use?

Timeframe	Energy used	Notes
Per hour	0.01 kWh	Steady-state draw
Per day	0.05 kWh	6 hours of runtime
Per month	2 kWh	Full month at daily duty cycle
Per year	19 kWh	Year-round load

Cost per slab — NEPRA Unprotected Residential (FY 2025–26)

Slab	Rs./unit	Per hour	Per day	Per month
1–100 units	16.48	Rs. 0.15	Rs. 1	Rs. 27
101–200 units	22.95	Rs. 0.21	Rs. 1	Rs. 37
201–300 units	27.14	Rs. 0.24	Rs. 1	Rs. 44
301–400 units	32.03	Rs. 0.29	Rs. 2	Rs. 52

Above 700 units	42.72	Rs. 0.38	Rs. 2	Rs. 69

Energy charge only. Add ~Rs. 5/month for FPA + QTA at typical rates, then 18% GST on the total. Electricity duty and PTV fee are also stacked — see the full electricity bill calculator for the complete tax pass-through.

Protected consumers (≤200 units, 6-month rule)

Slab	Rs./unit	Per month cost
1–100 units	11.69	Rs. 19
101–200 units	14.16	Rs. 23

Check your Protected consumer eligibility — the ≤200 unit rule is strict and one bad month resets the 6-month counter.

Cut the running cost

Never use incandescent or CFL — they cost 5–8× more per lumen-hour.
Install motion sensors on stairwell and washroom bulbs; typical run-time drops by 70%.
Daylight-white LEDs (5,500 K) feel brighter than warm-white at the same wattage.

Fine print

9 W is the modern LED equivalent of a 60 W incandescent. Rooms with recessed lighting (10+ downlights) still add up quickly — sum the wattage.
