Why incandescent bulbs are better? Incandescent bulbs cost much less than their energy-efficient alternatives – mainly CFLs (compact fluorescent lamps) and LEDs (light emitting diodes). Incandescents are inefficient – 90% of the energy goes toward heat and only 10% toward light. Incandescents also don’t last as long as CFLs and LEDs. What are the disadvantages […]
