Many Indian factories still run incandescent tower lights. The periodic bulb replacements feel routine, but the true cost is staggering when you add it up.
The Hidden Costs
An incandescent bulb lasts 3-6 months on two shifts. A factory with 50 machines needs 300-600 bulb replacements per year, consuming 75-300 man-hours of labour. Energy: incandescent draws 5-10 watts per layer versus 1-2 watts for LED — an extra 16,000-28,000 rupees per year across 50 machines. Plus progressive dimming and heat-induced lens damage.
The LED Advantage
Over 5 years, 50 machines with incandescent need 1,500-3,000 bulb replacements costing 1.5-3 lakh in parts plus hundreds of hours of labour. LED: zero replacements, consistent brightness for 50,000+ hours. Pays for itself in year one.
