Comparison between Incandescent and LED

What are Incandescent Bulbs?

Incandescent bulbs are traditional light bulbs that have been used for many years. They produce light by using a filament wire that is heated until it glows. The light produced is warm and soft, but they are not very energy-efficient.

Examples of Incandescent Bulbs

  • A-shaped bulbs
  • Globe bulbs
  • Candle bulbs
  • Spotlight bulbs

Uses of Incandescent Bulbs

Incandescent bulbs have been used in various applications such as residential lighting, commercial lighting, and decorative purposes.

What are LED Bulbs?

LED (Light Emitting Diode) bulbs are a more advanced technology. They produce light by passing an electric current through a semiconductor material, which emits light energy. LED bulbs are highly energy-efficient and have a longer lifespan compared to incandescent bulbs.

Examples of LED Bulbs

  • A-shaped bulbs
  • Tube lights
  • Floodlights
  • Strip lights

Uses of LED Bulbs

LED bulbs are used in various applications such as residential lighting, commercial lighting, automotive lighting, and outdoor lighting.

Differences between Incandescent and LED Bulbs

Difference Area Incandescent LED
Energy Efficiency Less energy-efficient, waste energy as heat Highly energy-efficient, convert most energy into light
Lifespan Shorter lifespan, typically 1,000 hours Longer lifespan, typically 25,000 to 50,000 hours
Brightness Produce warm and soft light Produce cool and bright light
Heat Emission Produce significant heat Produce little to no heat
Environmental Impact Contain harmful substances like mercury Environmentally friendly, no hazardous substances
Size and Shape Varieties Limited options Wide range of options
Instant Illumination Take some time to reach maximum brightness Instantly reach full brightness
Dimming Capability Can be dimmed with compatible dimmers Can be dimmed, but not all LED bulbs are compatible with all dimmers
Durability Fragile and prone to breakage Durable and resistant to breakage
Cost Relatively inexpensive Initially more expensive, but long-term cost-effective due to energy savings and longer lifespan


In conclusion, LED bulbs are a more advanced and energy-efficient lighting solution compared to incandescent bulbs. They offer several advantages such as higher energy efficiency, longer lifespan, cooler operation, and environmental friendliness.
