Commercial Fluorescent Light Fixtures: The Ultimate FAQs Guide

In this guide, I will show you how to choose the best commercial fluorescent light fixture.

It covers everything including main parts, advantages, and quality testing, just to mention a few.

So, if you want to be an expert in light fixture for your business, read this guide.

What is Commercial Fluorescent Light Fixtures?

This type of commercial light fixture applies traditional fluorescent technology and is generally installed into ceilings and enclosed with a frosted lens.

Fluorescent tube

Based on the quantity of light needed in the commercial space, conventional fluorescent lamps normally have between 1 to 4 bulbs.

The luminaires are considered as one of the more energy-efficient and longer-lasting alternatives for commercial lighting.

Which are the Main Parts of Commercial Fluorescent Light Fixtures?

Some of the main parts of the fluorescent tube include:

· Fixtures

Fixtures can be decorative or functional, though its main role is to give safe casing for the ballast and tube.

This component of fluorescent light luminaires also holds connections to a source of power, like batteries or electrical cables.

Components of fluorescent light fixture

· Tube

The tubes carry the inert gas and mercury.

Traditional commercial fluorescent light fixtures have tubes formed into straight cylinders.

On the other hand, compact fluorescent lamps are tubes formed into incandescent bulbs shape in a swirl or curved in half to form letter “U’.

 Parts of fluorescent tube

· Ballast

This is a magnetic coil that controls the current flowing to the fluorescent lamps and supplies enough voltage to power the bulb.

· Starter

Only older commercial fluorescent lighting luminaires come with starters that are tiny metallic cylinders.

The primary purpose of the starter is to delay entry of electric current into the fluorescent tube.

· Electrodes

Commercial linear fluorescent light fixtures have dual sets of electrodes, with each at either edge of the tube.

The electrodes link to the fixture through 2 tiny metal prongs that are noticeable outside the fluorescent tube.

However, the electrodes are concealed in CFLs since they come with the screw-type base.

The electrodes are hidden in CFLs because they are in the screw-type base.

Conversely, CFLs can as well be manufactured without electrodes.

In this scenario, they depend on a swerve from low-pressure gas emission to radiate light.

Which are the Types of Commercial Fluorescent Light Fixtures?

Here are some types of commercial fluorescent light fixture you should consider:

· Linear Fluorescent Tubes

Linear fluorescent tube

These are the most popular types of commercial fluorescent light fittings that come as straight glass cylinders.

There are three common types of linear fluorescent lamps, including T5, T8, and T12 fluorescent tubes, with the diameter being the main difference.

· Fluorescent Bent Tubes

Bent florescent tube

As the name hints, this type of fluorescent lamp is curved in a U-shape.

Therefore, you could as well refer to them as U-bent fluorescents.

They come in various options, with the most common type being fluorescent bent T8 having 6-inch leg spacing.

· Fluorescent Circline Tubes

 Circline flourescent tube

These types of commercial fluorescent light fixtures produce a glowing halo effect and are commonly used in decorative applications.

· Compact Fluorescent Lamps

Compact fluorescent lamp

Compact fluorescent lamps are an improvement on conventional fluorescent technology.

As opposed to traditional types of fluorescent, CFLs adopt a spiral design making then compact.

This type of commercial fluorescent lighting fixture has an integrated ballast and can screw into an ordinary base socket.

They are a more energy-efficient alternative for standard incandescent applications.

What are the Advantages of Commercial Fluorescent Light Fixtures?

The main benefits of installing commercial fluorescent light fixtures include:

· Energy Efficiency

Replacing halogen or incandescent lights with commercial fluorescent light luminaires ensures efficient use of energy.

This is because the latter consumes less power.

Installing commercial fluorescent light fittings can lead to an almost 40 percent drop in your electricity bill.

· Wide Selection of Color Temperatures

Fluorescent lights are an ideal choice if you require a truly cool temperature commercial space, as they provide color as 6500K color temperature.

The variety of colors from cool to warm is a point of versatility for commercial fluorescent light luminaires.

· Cost-Effective

In comparison to LED light fixtures, fluorescent lighting fittings are more affordable.

In fact, advancement of LED luminaires has helped in driving down the price of commercial fluorescent light fixtures over the years.

Why do Commercial Fluorescent Light Fixtures require a Ballast?

The main role of ballast in commercial fluorescent lighting fitting is to convert the AC from the power supply to a stable and direct flow of electricity.

This assists in stabilizing and maintaining the chemical reaction taking place within the bulb.

What is the Difference between Commercial Compact Fluorescent Lamps and Commercial Linear Fluorescent Tubes?

To explain, both commercial linear fluorescent tubes and CFLs apply similar technology to generate artificial light.

Nevertheless, the greatest difference between the two is the size and configuration or form factor of the commercial CFL.

Compact fluorescent lamps are basically an improvement of the linear fluorescent technology that consumes less energy.

Their design allows them to fix into a recessed can or screw into an ordinary incandescent socket.

They are commonly referred to as “plug-in” or “spring lamps” based on the shape and application.

How does a Commercial Fluorescent Light Fixture Function?

Electric current first flows into the commercial fluorescent light fixture via a ballast.

In turn, the ballast supply the electricity into the fluorescent bulb pins on either ends.

After entering through the pins, the current moves to the electrodes in the secured glass tube, which is maintained under low pressure.

Electrons start to travel from one end of the tube to the other, moving from one cathode to another.

Within the fluorescent tube are mercury and inert gases which get excited stirred by the electric current.

The flow of electricity causes the mercury to vaporize and reacts with the inert gases to generate an invisible ultraviolet light.

This invisible UV light radiates the phosphor powder layer on the inner wall of the fluorescent bulb, beaming white “fluorescent” light.

The fluorescent ballast regulates the current flow across the tube.

It causes a stream of current arc across the bulb when the starter unlocks.

Moreover, it maintains the correct rate of current flow once the fluorescent lamp is glowing.

The starter in most commercial fluorescent fixtures is an automatic switch.

After detecting that the tube is glowing, it remains open and closes when you de-energize the commercial lighting luminaire.

How do you Maintain Commercial Fluorescent Light Fixtures?

The replacement method is the easiest and simplest way of servicing commercial fluorescent light fixtures.

If you feel that a component may be faulty, replace it using a new one.

· Fluorescent Tube

Begin by checking the fluorescent tube.

You can either fix a new bulb or, when not sure whether the old bulb is blown out, try it out in another fixture.

· Starter

If the fluorescent tube has no problem, try replacing the starter.

All fluorescent bulb starters are graded by wattage.

Therefore, it is crucial to utilize the correct starter for your commercial fluorescent light fixture.

Fix a new one by installing it into the socket and spinning it to fasten it into position.

· Ballast

Rating of ballast is as well based on wattage thus, a replacement ballast should have rating matching that of the commercial fluorescent light fixture.

However, the ballast is the last probable component to break down and most complex to replace.

Therefore, it should be last to replace during maintenance.

To change a defective ballast, de-energize the circuitry then disassemble the lighting fixture.

Move cables from the old ballast to the replacement one.

You should transfer the wires one after the other to prevent incorrect connections.

Lastly, reassemble the commercial fluorescent lighting luminaire.

· Switch

In case the tube, starter and ballast are all functioning correctly but the bulb still does not light, access for a faulty switch.

If the commercial lighting fixture is managed by a wall switch, change the switch.

If the luminaire is controlled by a push-button switch, replace the faulty one using a new one of similar type.

Remember to de-energize the circuitry prior to replacing the circuit by tripping the circuit breaker or removing the fuse.

What is Color Shifting in Commercial Fluorescent Light Fixtures?

When you observe a large space lit by fluorescent tubes, you will likely see different colors emitted from the ceiling. This concept is referred to as “color shifting”.

The longer the tube burns, the higher the chance of a shift in chemical properties that result in imbalanced reaction.

This makes the commercial fluorescent light fixture less bright and less white than it was before.

Therefore, when consistency is very essential to your lighting project, then you may consider group re-lamping the fluorescent fixtures.

By replacing all the lights in groups, you can remedy the problem of inconsistent brightness and colors in your commercial space.

What are the Uses of Commercial Fluorescent Light Fixtures?

Here are some of the common applications of commercial fluorescent lighting fixtures:

· Commercial Offices

The key priority in most offices is general lighting which is effective for the office setup.

Due to this fact, fluorescent bulbs are the main type of commercial lighting fixture utilized in the majority of office spaces.

· Warehouses

T5s are the common type of commercial fluorescent lighting used in warehouses or high-bay ceiling that require a significant quantity of light.

They generate more lumens and have a longer lifespan (up to 90,000 hours) than other fluorescent lighting fixture types.

· Hospitals

Same as office spaces, hospitals as well use linear fluorescent light luminaires.

This helps to generate a white, smooth, effective light source and to save cost on energy.

· Retail Stores

When developing an eccentric lighting design for your retail store, it is recommended to apply the 20/80 rule.

80 percent of the lighting needs to be ambient lighting, while 20 percent of it needs to be decorative and distinctive.

In the majority of retail shops, 80 percent ambient lighting is mainly achieved through installing commercial fluorescent lighting fixtures.

Are there Disadvantages of Commercial Fluorescent Light Fixtures?

Here are the main disadvantages of installing commercial fluorescent lighting fittings:

· Lumen Depreciation or Color Shifting

As mentioned earlier, the longer fluorescent lamp glows, the higher the probability of a shift in chemical properties resulting in an imbalanced reaction.

This makes the fluorescence less brilliant and less white in comparison to how it was earlier.

The light output of the fixture depreciates with time.

· Harsh Light

Commercial fluorescent light luminaires are not kind on the eyes.

In case your eyes are commonly dry or bloodshot, you need to examine the light source you use the better part of day.

For instance, linear fluorescent lamps in parabolic troffers installed in an office may lead to subconscious squinting because of the harsh light.

A better option would be a linear fluorescent lamp within a center basket troffer that soothes the light reaching the ground.

· Warm-up Period

You may be compelled to wait for some time for the commercial fluorescent light fixture to attain its full brightness.

This duration is referred to as warm-up period and it might range between 10 to 30 seconds.

· Recycling Cost or Environmental Impact

The energy-saving benefit of fluorescent lights outweighs their recycling cost.

However, there is extra expenses to ensure that the tubes are correctly discarded.

The mercury component of the tube also possesses an environmental, safety, and health hazard.

How do you Troubleshoot Commercial Fluorescent Light Fixtures?

Let’s look at the ways of troubleshooting common problems in commercial fluorescent Light fixtures:

· Bulb does not Light

Assess the power supply and confirm whether the tube is fixed correctly in the socket.

Subsequently, change the tube or tubes.

If the replacement tube does not glow, utilize a voltage detector or multimeter to examine whether the fixture is receiving power.

Do this both at the sockets and the switch.

If there is the power supply, try changing the starter, in case your commercial fluorescent lighting fitting has one.

Replacing the ballast should be the last step.

· Tube Flickers

First, confirm to ensure that the fluorescent tube is tightly installed in the sockets.

Subsequently, examine the tube to ensure it not blown out, shown by blackening at the ends.

You can as well assess it for continuity using a multimeter.

Moreover, if changing the tube does not solve the flickering problem, substitute the starter.

Nevertheless, if the problem continues, change the ballast. As a final option, replace the entire commercial fluorescent lighting fixture.

· Fixture Buzzes or Hums or Buzzes

In this situation, replacing the ballast is the best solution.

Does Temperature Affect the Performance of Commercial Fluorescent Light Fixtures?

The operation of commercial fluorescent lighting luminaires is significantly influenced by the temperature of the wall of the tube.

Temperature also has impact on the partial pressure of vaporized mercury within the bulb.

Because mercury liquefies at the coolest point inside the tube, careful design is required to keep that point at optimum temperature.

Utilizing an amalgam together with other metals minimizes the vapor pressure and lengthens the range of optimum temperature upward.

Nonetheless, there is still a need to control the “cold spot” on the tube wall to prevent condensation.

High-output commercial fluorescent light luminaires have features like internal heat-sinks or deformed fluorescent tubes to control mercury distribution and cold spot temperature.

Heavily loaded types, like CFLs, equally have heat-sink points in the bulb to keep the pressure of mercury vapor at an optimum level.

What is Correlated Color Temperature in Commercial Fluorescent Light Fixtures?

Correlated color temperature refers to the measurement of the intensity of whiteness of a source of light in comparison with a blackbody.

Commercial fluorescent light fixtures are produced to a selected CCT by modifying the mixture of phosphors within the tube.

Warm-white fluorescent lamps have a CCT of 2700K, while neutral-white types of commercial fluorescent luminaires have a CCT of 3000K to 3500K.

Furthermore, cool-white types have 4100K CCT and are commonly used for office lighting.

Similarly, Daylight fluorescent lamps, which are bluish-white, have 5000K to 6500K CCT.

High correlated color temperature commercial lighting typically needs higher levels of light.

At dimmer levels of illumination, the human eye regard lower CCT as more pleasing as compared through the Kruithof curve.

 8 CCT

Can you use Commercial Fluorescent Light Fixture as a Grow Light?

Yes, commercial fluorescent light fixtures are perfect for plants having low to medium light needs.

They have a reduced heat signature and emit a decent light spectrum for growing.

The light luminaires give more blue wavelengths compared to any other type of grow light.

Moreover, they also offer a full white spectrum of light, making them an ideal options for early growth phases.

There are various types of fluorescent grow lights that come in different sizes comprising of T5, T8, and T12.

The slimmer the tube, the brighter and more efficient it is because of the smaller surface area.

Using fluorescent lighting fixtures as grow light is a more energy-saving alternative than using incandescent lights.

Nevertheless, they incline to be a more costly options.

What are the Signs of a Bad Commercial Fluorescent Light Fixture Ballast?

The following signs from your commercial fluorescent light fixture may be signal of a bad ballast:

· Flickering

If the tube blinks at times, it does not imply that the bulb is nearly blowing out. Nevertheless, it could be an indication of a spoilt ballast.

· Buzzing

Bad ballast usually hums or buzzes when they are about to spoil.

You should examine the ballast whenever you notice this problem.

·  Delayed Start

Your ballast is defective if the lighting fixture begins to behave as HID when it’s switched on and slow to attain full brightness.

· Low Output

Low lumen output or dim light is usually as a result of aging fluorescent ballast or old lighting fixture.

· Inconsistent Lighting Levels

It is normal for commercial fluorescent light fixtures to experience fading and color imbalance.

The lamp will produce varying levels of light at different phases of its lifespan.

However, inconsistent lighting and dark corners in your commercial space could be due to bad ballast and not just the lamps.

How Long can a Commercial Fluorescent Light Fixture Last?

Typically, a commercial fluorescent lighting fixture has a lifespan 10 to 20 times longer in comparison to incandescent lamps.

In addition, during ordinary test conditions, the luminaires last 6,000 – 80,000 hours, functioning 8 hours every day.

How do you Test Quality of Commercial Fluorescent Light Fixtures?

Here are the tests for checking the quality of commercial fluorescent lighting fittings:

Fluorescent light fixture

· Lamp Test

This test specifically examines the presence of gas inside the fluorescent tube.

It entails sending an impulse of energy that lights up the bulb in case there is gas within it.

· Ballast Test

As the name suggests, the quality test determines whether the fluorescent ballast in functioning.

· Non-contact Voltage Test

The quality test swiftly confirms the availability of voltage without getting into contact with the power source.

· Pin continuity Test

This test helps to determine whether the fluorescent tube filaments have continuity.
