Comparing the Pros and Cons of Fluorescent Tubes for Efficient Lighting Needs

Introducing Fluorescent Tubes

Fluorescent tubes have been lighting buildings since the 1930s. They are long cylindrical tubes that contain mercury vapor which emits ultraviolet light when excited by electricity. The inside of the tube is coated with phosphors which convert the ultraviolet light into visible light. Fluorescent tubes are a type of gas-discharge lamp.

How Fluorescent Tubes Work

Here is a quick overview of how fluorescent tubes work:

• Electricity flows through the tube electrodes, ionizing the mercury vapor and producing ultraviolet light
• The ultraviolet light hits the phosphor coating, causing it to fluoresce and emit visible light
• The tube ends contain filaments or electrodes that regulate the electricity flow
• A ballast provides proper voltage to start and operate the fluorescent tube

Benefits of Fluorescent Tubes

Fluorescent tubes have some key advantages over incandescent bulbs:

• More energy efficient - Use around 75% less power than an equivalent incandescent
• Long life - Average 10,000 to 20,000 hours compared to 1,000 for incandescents
• Produce less heat - Fluorescents stay cooler than hot incandescent filaments

Types of Fluorescent Tubes

There are many varieties of fluorescent tubes available today. Some common types include:

Fluorescent tubes come in a wide range of light color temperatures for different needs. Cool white tubes give bright energizing light while warm white tubes create a calm relaxed ambiance.

Choosing and Installing Fluorescent Tubes

When selecting fluorescent tubes, consider light color, brightness in lumens, and the tube length. Make sure to get a tube that is compatible with your existing fixtures. Choose an energy efficient T8 or T5 tube. Follow the manufacturer instructions to safely install fluorescent tubes.

With their efficiency and long life, fluorescent tubes are a great lighting option. Their cool operation also makes them ideal for applications like garages and kitchens. Fluorescent technology continues advancing, delivering even better performing tubes to meet today's lighting needs.

What Are Fluorescent Tubes and Why Use Them?

Fluorescent tubes are gas discharge lamps that use electricity to create illumination. They are long cylindrical tubes that come in a range of diameters, colors, and light outputs. Fluorescent tubes last much longer and are far more efficient than old-fashioned incandescent light bulbs.

How Fluorescent Tubes Work

Here is a quick overview of how fluorescent tubes produce light:

• The tube contains a small amount of mercury vapor and argon gas
• Electrodes at each end emit electrons when current flows through them
• The electrons collide with and energize the mercury atoms, causing ultraviolet radiation
• The interior of the tube is coated with fluorescent phosphors
• The phosphors absorb the UV rays and emit visible light

Benefits of Fluorescent Tubes

There are several excellent reasons to choose fluorescent tubes for lighting needs:

• Very energy efficient - Use 60-80% less power than equivalent incandescent bulb
• Long lasting - Keep working 10-20 times longer than incandescents
• Produce little heat - Stay much cooler than hot incandescent filaments
• Variety of color temperatures - From warm white to daylight colors

Types of Fluorescent Tubes

There are many types of fluorescent tubes on the market. Some common varieties include:

Choosing the right fluorescent tube type and color for your needs will provide excellent illumination and energy savings.

Fluorescent Tubes Light the Way

With their unmatched efficiency and long life, fluorescent tubes should be considered over old incandescent bulbs for most lighting situations. Fluorescent technology continues to advance, giving businesses and consumers durable and sustainable lighting solutions.

Comparing Fluorescent Tubes to Incandescent and LED Bulbs

When choosing lighting for your home or office, three of the main options are fluorescent tubes, incandescent bulbs, and LED bulbs. Each technology has its pros and cons.

How They Produce Light

The three types of lights use different methods to produce illumination:

• Incandescents pass current through a wire filament to heat it until it glows
• Fluorescents utilize mercury vapor to create UV light that excites phosphors to emit visible light
• LEDs (light emitting diodes) use semi-conductors and electronics to generate light particles called photons

Power Efficiency

One major consideration is how efficiently the bulbs produce light:

• Incandescents are very inefficient - 10% of energy goes to light, 90% becomes heat
• LED bulbs are the most efficient, converting over 90% of energy into light
• Fluorescents are in the middle, converting 25-35% of power to useful light

For example, replacing a 60W incandescent with a 15W fluorescent tube can save up to 80% on lighting costs while delivering the same brightness.

Lifespan

Bulb longevity is another key factor:

• Incandescent bulbs last only 750-1,000 hours
• LED bulbs can keep working up to 50,000 hours
• Fluorescent tubes last 10,000-20,000 hours on average

This means fluorescents provide at least 10 times the lifespan of incandescent lights.

Light Quality

Incandescents provide attractive warm light, but waste most of their energy as heat. Fluorescents and LEDs are getting better at replicating incandescent light quality.

The Best Choice Depends on Your Needs

For most general lighting applications, fluorescents provide the best combination of efficiency, life span, and improving light quality. However, incandescents may be preferred when warm aesthetics are vital, while LEDs offer the ultimate in durability and efficiency.

By understanding the strengths of each technology, you can choose the type of lighting that best meets the needs of your home or office.

Fluorescent Tube Varieties and Applications
