If you’re looking to replace the lighting in your home, you might be wondering what the difference between LED and incandescent bulbs is. Which one should you buy? Each type of bulb has certain advantages over the other. Use this head-to-head comparison of LED and incandescent bulbs to determine which type is the best option for your home.

Incandescent Bulbs

Incandescent bulbs are classic light sources you most likely already have in your home. These bulbs light up when a copper wire filament heats up inside the gas-filled bulb to a temperature that results in light.

  • Benefits of Incandescent Lights

    First and foremost, incandescent lights are relatively cheap to manufacture, which makes them cheap to purchase. As traditional light sources, these bulbs are also widely available and adaptable to various ranges of voltages, outputs, and currents.

    These bulbs also have a high color rendering index (CRI), meaning they give off an accurate depiction of color in relation to the light they emit. Incandescent bulbs’ CRI rating does drop over time; however, the drop is only slight.

  • Downsides of Incandescent Lights

    Incandescent lights do have a few downsides to consider when you’re determining what light is best for your home. Incandescent lights have one of the worst energy-efficiency ratings in light bulbs, making them unsustainable and resulting in higher electric bills.

    Incandescent lights also have relatively short life spans, operating for roughly 1,000 hours per bulb. Lastly, incandescent lights are omnidirectional, meaning they produce light in all directions. This can be inefficient because the light must be directed to the specific spaces that need it.

LED Bulbs

LED stands for light-emitting diodes. A diode is an electrical device in which electricity flows through two electrodes. Diodes are made of semi-conductive materials, meaning they conduct electricity based on specific currents, voltage, and light intensity. When a current passes through a semiconductor, the light will emit. There’s much more behind how LED lights work and the specific colors and temperatures they give off, but diodes are at the base of LED bulb anatomy.

  • Benefits of LED Lights

    LED lights have many benefits that incandescent lights cannot offer. They’re extremely energy-efficient and have a longer life span. One LED light bulb can run for as long as 50 to 100 incandescent bulbs. LED bulbs also have a shorter warm-up phase and offer directional light to further their efficiency.

  • Downsides of LED Lights

    The biggest downside of LED lights is their cost. Currently, the upfront purchase for an LED bulb is more than that of an incandescent bulb. However, their long life span can balance out this initial cost.

    The differences between LED and incandescent lightbulbs provide strong advantages for both options to be used in your home. If you’re looking for a cheap, widely available option, incandescent might right for your home. You can also look to LED bulbs for a long-lasting, energy-efficient light source.
