Savings by Using LED Lights: Cost, Payback, and Long-Term Benefits

LED lighting has become one of the most effective ways to reduce electricity bills at home and in industries. While the upfront cost of LED lights is slightly higher compared to conventional tube lights, the annual savings, longer lifespan, and reduced maintenance costs make them a far superior choice. Let’s break down the numbers and see why LEDs are a smart investment.

Conventional Tube Light vs LED Tube Light – Power Consumption

1. Conventional Tube Light (with choke)

• Tube Wattage: 36 W

• Choke Wattage: 36 W

• Total Consumption per Hour: 72 W (0.072 kWh)

• Daily Usage (10 hours): 720 Wh (0.72 kWh)

• Monthly Usage (30 days): 21.6 kWh

• Annual Usage: 262.8 kWh

• Electricity Tariff (avg.): ₹8 per unit

• Annual Cost: ₹2,102

2. LED Tube Light

• Wattage: 20 W

• Total Consumption per Hour: 20 W (0.02 kWh)

• Daily Usage (10 hours): 200 Wh (0.20 kWh)

• Monthly Usage (30 days): 6 kWh

• Annual Usage: 72 kWh

• Electricity Tariff (avg.): ₹8 per unit

• Annual Cost: ₹576

Annual Savings with LED Lights

• Annual Power Cost (Conventional): ₹2,102

• Annual Power Cost (LED): ₹576

• Savings in Power Consumption: ₹1,526

Now, consider initial replacement cost of LED tube: ₹300.

• Net Annual Savings: ₹1,226

• Payback Period: ~1.5 months (after which all savings are profit)

Why LEDs Are the Future of Lighting

1. Energy Efficiency: LEDs consume up to 70% less electricity than conventional tube lights.

2. Longer Life: With up to 50,000 hours of lifespan, LEDs last 2–3 times longer.

3. Low Maintenance: No chokes or starters, hence fewer breakdowns.

4. Falling Prices: With mass production, LED costs are dropping rapidly.

5. Warranty Assurance: Most manufacturers offer 2–3 years warranty, ensuring peace of mind.

6. Eco-Friendly: Reduced carbon footprint and lower e-waste due to longer life.

Practical Tip

You don’t need to replace the entire fixture. Modern LED tube rods are designed to fit into existing fittings – you just remove the choke and starter. This makes the switch to LEDs easier and cost-effective.

Conclusion

Switching to LED lights is not just an eco-friendly choice but also a financially rewarding decision. For every tube light replaced, you save ₹1,200+ per year. Multiply this by all the tube lights in your home or workplace, and the savings run into thousands of rupees annually.

With short payback, reduced maintenance, long lifespan, and lower electricity bills, LEDs are the smarter, greener, and more economical option for the future.
