Incandescent Light Bulb vs LED: An Electrician’s Opinion & Advice

Hey there, homeowner! At CSK Electric, we get asked all the time about the best lighting options. Should you stick with those classic incandescent bulbs or make the switch to LED bulbs?

It’s a big decision, and we’re here to break it down for you with an electrician’s know-how. Here is the nitty-gritty of incandescent lighting versus LED lights—think energy use, cost, and that cozy glow we all love.

What are Incandescent and LED Light Bulbs?

Incandescent Light Bulbs

Incandescent light bulbs are the classic type of lighting that many of us grew up with. These bulbs work by passing electricity through a thin wire filament, usually made of tungsten, until it gets so hot that it glows, producing visible light.

This process, known as incandescence, is similar to how a campfire emits light and heat. Incandescent bulbs have been the go-to choice for over a century, thanks to their warm, inviting glow and simple design.

They come in various shapes, sizes, and colors, making them versatile for different lighting needs. However, they are not very energy efficient, as a significant portion of the energy is lost as heat rather than visible light.

LED Light Bulbs

LED (Light Emitting Diode) light bulbs represent a more modern and energy-efficient lighting technology. Unlike incandescent bulbs, LEDs use semiconductors to produce light. When an electric current passes through a microchip, it illuminates tiny light sources called LEDs, a process known as electroluminescence.

This method is highly efficient, converting most of the energy into visible light with minimal heat loss. LED bulbs have gained popularity in recent years due to their long lifespan, energy efficiency, and versatility.

They are available in a wide range of colors and brightness levels, making them suitable for various applications, from home lighting to commercial use.

The main difference in this LED vs incandescent comparison? Incandescent bulbs heat a filament to emit light, while LEDs—short for light emitting diodes—use a tiny chip to produce visible light with very little heat.

We’ve wired countless homes at CSK Electric, and we’ve seen firsthand how these lighting technologies shape energy consumption and light quality. Incandescent lamps guzzle electricity and pump out heat, while LED technology sips power and stays cool. Which sounds better for your hydro bill?

Key Differences Between Incandescent and LED Bulbs

When comparing incandescent bulbs to LED bulbs, several key differences stand out. First and foremost is energy efficiency. LED bulbs are significantly more energy-efficient, using up to 90% less energy to produce the same amount of light as incandescent bulbs.

This efficiency translates to lower energy consumption and reduced electricity bills. Secondly, the lifespan of LED bulbs far exceeds that of incandescent bulbs. While an incandescent bulb might last around 1,000 hours, an LED bulb can shine for up to 25,000 hours or more. This means fewer replacements and less hassle over time. Lastly, LED bulbs are more environmentally friendly.

They produce very little heat, emit no UV radiation, and contain no toxic chemicals like mercury, making them a safer and more sustainable choice for lighting. Overall, LED bulbs offer a more cost-effective and eco-friendly solution compared to traditional incandescent light bulbs.

Incandescent Light Bulbs

Incandescent bulbs have been the go-to traditional light bulbs for over a century. They work by running electricity through a filament until it glows hot—think of it like a mini campfire in a glass shell. That visible filament gives off a warm, white light that’s tough to beat for ambiance.

But here’s the catch: only about 10% of the energy turns into light, while the rest escapes as heat. At CSK Electric, we’ve replaced tons of these in older homes—especially in commercial buildings where frequent replacements eat into budgets.

They’re cheap upfront, with a lower up front cost that’s easy on the wallet. Still, their short lifespan means you’re swapping them out way too often. Ever wonder why your grandma’s attic is full of burnt-out bulbs? That’s incandescent lights for you—simple, classic, but not exactly energy efficient.

LED Bulbs

Now, let’s flip the switch to LED lighting. These little champs use light emitting diodes to create bright, crisp light without breaking a sweat. Unlike incandescent lamps, LED lights turn most of their energy into visible light—up to 95%—leaving very little heat behind. We’ve installed LED technology in homes across our service areas, and customers rave about the same brightness with way less wattage.

LED bulbs prove their worth with a lifespan that blows incandescent out of the water—think 25,000 hours versus a measly 1,000. They’re the longer lasting choice, hands down. Plus, they come in all sorts of styles, from soft white light to daylight vibes. Ready to ditch the ladder and enjoy bulbs that don’t quit?

PROs & CONs of Incandescent Lights

Why Incandescent Lights Shine

Incandescent bulbs bring that warm, dim glow perfect for ambient settings like your living room or bedroom. They’re dirt cheap to buy—sometimes just a buck or two—and they don’t mess around with mercury, unlike some other bulbs. That visible filament? It’s a vibe, making them a preferred choice for vintage lovers.

Where They Fall Short

Here’s the downside: energy efficiency isn’t their strong suit. They waste most of their juice as heat emitted, not light. Their short lifespan means constant replacements, especially in commercial settings. Carbon emissions pile up too, since they hog electricity like nobody’s business. At CSK Electric, we’ve seen them jack up bills faster than you can say “flickering filament.”

PROs & CONs of LED Light Bulbs

LED’s Winning Edge

LED bulbs are the kings of energy efficiency, slashing energy consumption by up to 75% compared to incandescent lights. They’re longer lasting, cutting down on frequent replacements, and they’re tough—perfect for cold conditions. No mercury here either, so the environmental impact is lighter. Plus, LEDs emit light in every shade, giving you design flexibility for any space. Additionally, LED's cost savings are significant over time, making them a financially smart choice.

The Flip Side

Upfront, LED lights cost more—sometimes $5 to $10 a pop. Some folks say the light quality feels too harsh, especially cheaper models. Dimming can be tricky without the right setup, and in rare cases, they don’t play nice with old wiring. We’ve fixed that for clients with a quick electrical upgrade.

Considerations for Cold Conditions

Living in Canada, we know cold conditions can mess with lighting choices. Incandescent bulbs actually thrive in low temperatures—they heat up fast and don’t care about the chill. But LEDs?
