Frequently Asked Questions
How much energy does an LED save vs an incandescent bulb?
An LED bulb uses about 85% less energy than an equivalent incandescent. A 9W LED produces the same light as a 60W incandescent. Over 1 year at 8 hrs/day, that is 149 kWh saved per bulb.
How long do LED bulbs last?
Good quality LED bulbs last 15,000–25,000 hours. At 8 hours per day, that is 5–8 years. Incandescent bulbs typically last only 1,000 hours (about 4 months at 8 hrs/day).
What is the best LED wattage to replace a 60W bulb?
A 9W LED = 60W incandescent (800 lumens). A 7W LED = 40W incandescent. A 13W LED = 100W incandescent. Look for lumens (light output), not just watts, when buying LEDs.
Are LED bulbs available in Nigeria?
Yes. LED bulbs are widely available in computer villages, electronics shops, and supermarkets across Nigeria. Brands like Panamax, Philips, Synertek, and local imports are common. Prices range from ₦500 to ₦2,500 per bulb.
Will switching to LED reduce my generator fuel cost too?
Yes. Since LED uses 85% less power for lighting, switching 10 bulbs from 60W to 9W reduces lighting load from 600W to 90W — saving 510W. Over 4 hours of generator use per day, this saves about 0.2L of petrol daily (₦240 at ₦1,200/L).
