Fluorescent vs Incandescent vs LED Light Bulbs: Which is Best?

In 1870, Thomas Edison, the inventor many of us know, created the incandescent light bulb using bamboo filament. It didn’t stop there, though. Later, in 1934, General Electric launched the fluorescent bulb, taking the world by storm. Again, in 1962, Nick Holonyak invented the first LED light bulb.

With the evolution of lighting technology, today's homeowners have three main types to choose from: LED, fluorescent, and incandescent bulbs. But which is the most suitable for your home?

Dive in with us and discover the difference between LED, fluorescent, and incandescent light bulbs.

Incandescent (CFL) Bulbs

How Incandescent Light Bulbs Work

Incandescent light bulbs work by using a folded or spiral tube containing a fluorescent mercury vapor and argon coating. When electricity flows through the tube, the mercury and argon in the tungsten filament are fumed, creating invisible ultraviolet light. The UV light then interacts with the fluorescent coating inside, turning the light source into visible white light.

Energy efficiency

Compared to other light bulbs, incandescent (CFL) tends to use the most energy. Around 2% of the emitted is transmitted into visible light, and the remaining 98% is wasted as heat. Because of this, incandescent bulbs tend to burn out more frequently and must be replaced yearly.

Lifespan and Durability

On average, incandescent bulbs have a lifespan of 1000-1500 hours. If you use these bulbs on average around four hours a day, they may only last 3-6 months before a replacement is required.

Initial cost and savings

Typically a 60W bulb will cost around $2.70 dollars. To put this into perspective, if you used this bulb for around 1000 hours at $0.11 per Kwh a year, a 10 year operation for this bulb would cost $56.

However you need to take into account that an incandescent bulb lasts on average between 1000-1500 hours per year, it likely means you’ll need to replace the bulb each year. Which makes the cost of the original and replacement more expensive being on average around $93 over a period of 10 years.

Pros and Cons of CFL Bulbs

To help with your buying decision, here are the main pros and cons of incandescent lights:

Pros:

• Incandescent lights produce a warm light
• They create a cozy and snug atmosphere
• The bulbs are easy to source and are available in most shops
• They come in a range of shapes and sizes

Cons:

• Use a lot of energy, not energy efficient
• They have a shorter life span than other bulbs, require replacements
• They can overheat easily, becoming a fire hazard
• They tend to be costly due to their replacement
• A lot of electricity is wasted as heat

Fluorescent Bulbs

How Fluorescent Bulbs Work

Fluorescent bulbs have a glass tube containing a low-pressure mixture of gasses, particularly mercury, alongside neon, argon, xenon, and krypton. On the inside of this glass tube, there is a phosphor coating (which is fluorescent).

As soon as the electrical current is switched on, electrons are created, accelerating the gasses inside the tube and releasing ultraviolet radiation. This then hits the phosphor coating, producing white light.

Energy Efficiency

A fluorescent bulb is a more energy-efficient light bulb than traditional incandescent bulbs and provides more light output. They convert more electricity supplied into light and less heat, distributing light easily. Fluorescent light bulbs produce around 50-100 lumens per watt instead of 16, which happens with incandescent bulbs. On average, they last between 6000-15,000 hours.

Lifespan and Durability

On average, they last between 6000-15,000 hours. This bulb is often known to decrease replacement expenses and save energy. Typically, it lasts 10-20 times longer than an incandescent bulb. They are subject to flickering problems and can be sensitive to changes due to their longevity. However, if the voltage supply is altered, its lifespan can be lengthened.

Initial Costs and Savings

Fluorescent bulbs can cost around $2-$15 per bulb, making them more affordable than incandescent bulbs. However, while they are more affordable, they still need to be replaced, which means you have to factor in maintenance costs, too.

Pros and Cons of Fluorescent Lighting

Here are the main pros and cons of buying and installing fluorescent bulbs in your home:

Pros:

• More energy saving lasts 10-20 times longer than an incandescent bulb
• They have a high lumen output, making them light up large areas easily
• There are a lot of choices to choose from; they come in a range of color temperatures and tones
• Often more cost-effective due to having a longer lifespan

Cons:

• They contain a small amount of mercury, which triggers environmental hazards
• Sometimes, it can be prone to flickering and making noise
• When they are used for long periods, they can take time to reach full brightness (when turned on)
• Fluorescent bulbs are more costly to purchase than incandescent ones

Light Emitting Diodes (LED) Bulbs

How LED Technology Works

LED bulbs work by electrical current passing through a microchip in a plastic capsule, which emits light from small sources. Because they’re small, many LEDs combine to create a single light bulb.

Energy Efficiency

These light bulbs are highly efficient and tend to convert a large percentage (80%-90%) of electrical energy into visible light, with less wastage than incandescent bulbs. Moreover, LEDs produce minimal heat compared to incandescent and fluorescent bulbs, meaning they are safer and more efficient.

Lifespan and Durability

LED bulbs are known for their lifespan, lasting 25,000-50,000 hours, which is 50 times the lifespan of an incandescent bulb and 5 times that of a fluorescent lamp. On average, if you ran an LED for 6 hours a day each day, it would last for up to 23 years.

Initial Costs and Savings

The typical cost of LED bulbs varies between $2 and $20 per bulb, depending on the quality and type. At around 10 watts of power, it costs around $1.30 to run an LED bulb.

Pros and Cons of LED Bulbs

Here are the pros and cons of buying LED bulbs for your home:

Pros:

• Mod Lighting products use LED lights - check out our popular Mod Lighting fixtures
• Long lifespan lasting between 25,000-60,000 hours, much longer than incandescent bulbs.
• LEDs don’t have toxic materials such as mercury and are recyclable.
• They have a lower carbon footprint as they’re energy efficient.
• LEDs come in various colors and temperatures, allowing you to create different ambiances.
• They light up instantly without having to warm up
• They’re highly energy efficient, using 90% less energy than other bulbs, and they can significantly reduce electricity bills.

Cons:

• Not suitable for rooms that require widespread illumination as their light is directional
• They are known to emit more blue light than incandescent bulbs
• They tend to have an initial higher cost per bulb but are most cost-effective over time

Lumen & Wattage Comparison

To help you decide on the best bulb for your home, you must also know the difference between watts and lumens. These two play a key role in determining brightness and energy efficiency.

Lumens = The total amount of light visible distributed from one source; the higher the figure, the brighter the visible light is.

Watts (W)= The amount of energy a light bulb consumes.

So, when comparing light fixtures, consider the brightness, color temperature, and energy consumption.

Light source Wattage Lumens Color temperature Incandescent (CFL) 60W 800 Im 2700K (Warm white) Fluorescent Bulbs 110 W -800 IMm 2700k-3000K LED 170 W 800m Im 2700K-6500K

Are CFL or LEDs more cost-effective?

When it comes to the cost-effectiveness of both types of bulbs, you have to compare the initial costs, savings, and lifespan.

• Initial costs: On average, CFLs cost $2.70, whereas LEDs cost $2-$20 per, based on the type.
• Lifespan: CFLs last around 1000-15000 hours, whereas LEDs last around 25,000-50,000 hours
• Cost savings: Due to the short lifespan, incandescent lights can be more expensive, costing $93 per bulb every 10 years.

Comparing the two, CFLs are more expensive due to their high energy consumption and low lifespan.
