Incandescent Bulbs Waste 90% Of Their Energy

Traditional incandescent bulbs convert only 10% of their energy into light, while the rest is lost as heat. This inefficiency led to the rise of energy-saving alternatives like CFLs and LEDs.

Fluorescent Bulbs Contain Mercury

Compact fluorescent lamps (CFLs) might save energy, but they contain small amounts of mercury. If broken, they release toxic vapours, making proper disposal essential for environmental safety.
