Brightness and Lumen Output of TL and LED Lamps
Brightness and lumen output (the amount of light produced) from TL (Tubular Fluorescent Lamp) lamps and LED (Light Emitting Diode) lamps can vary depending on the type, size and brand. However, in general, LED lamps have several advantages in terms of lumen output and brightness compared to TL lamps:
TL lamps (Tubular Fluorescent Lamp):
- TL lamps produce around 50 to 100 lumens per watt (lm/W) depending on the type. This means that, for example, a 20 watt fluorescent lamp can produce around 1000 to 2000 lumens.
LED (Light Emitting Diode) lamps:
- LED lights are much more efficient in terms of lumen output. They can produce around 60 to 200 lumens per watt, depending on the type and quality. This means that a 10 watt LED lamp can produce around 600 to 2000 lumens or even more.
So, in general, LED lamps tend to produce more light (lumens) per watt of power produced. used compared to TL lamps. This is one of the main reasons why LEDs have become a more popular choice in modern lighting applications, as they are more energy efficient and can produce brighter light with lower power consumption. However, keep in mind that various factors such as lamp design, component quality, and brand can affect the actual performance of a particular TL or LED lamp. Therefore, it is always important to check the specifications of a particular product when selecting lamps for your lighting needs.
Energy Efficiency and Power Consumption of TL and LED Lamps
Energy efficiency and power consumption are two aspects which is important when comparing TL (Tubular Fluorescent Lamp) and LED (Light Emitting Diode) lamps. Let’s look at these two factors in their context:
Tubular Fluorescent Lamps:
-
Energy Efficiency: TL Lamps considered a more efficient alternative to conventional incandescent lamps. However, the energy efficiency of fluorescent lamps varies depending on the type and model. As a general guide, traditional fluorescent lamps can achieve an energy efficiency of around 50 to 100 lumens per watt (lm/W). For example, a 20 watt fluorescent lamp might produce around 1000 to 2000 lumens, which equates to an efficiency of around 50-100 lm/W.
-

-
How They Damage: TL Lamps tends to experience a decrease in light quality over time. They can become progressively dimmer, take several seconds to reach full brightness when turned on, or even experience flickering before finally turning off.
LED (Light Emitting Diode) lights :
-
Average Lifespan: One of the biggest advantages of LED lights is their much longer lifespan. High-quality LED lights can last up to 25,000 to 50,000 hours or more. This means that if an LED light is turned on for 4 hours a day, you may not need to replace it for 15 to 25 years or even more.
-
How it Breaks Down: LED lamps generally do not experience a significant decrease in light quality during their lifetime. They remain bright and consistent throughout the life of the lamp, and usually do not suffer from problems such as flickering or warm-up time.
From this comparison, it can be seen that LED lamps have a much longer service life compared to traditional TL lamps. This is one of the main reasons why LED lights are a more cost-effective option in the long run, even though their initial price may be higher than fluorescent lights. With a longer service life, you will also reduce replacement costs and energy expenditure on more frequent lamp replacements.
Instant Warm-up Time and Performance of TL and LED Lamps
Heat-up time and performance instant are two important factors that differentiate TL (Tubular Fluorescent Lamp) lamps and LED (Light Emitting Diode) lamps. Let’s look at these two factors in their context:
Tubular Fluorescent Lamp:
-
Heat Up Time :TL lamps take time to reach full brightness after being turned on. This happens because the TL lamp requires several seconds to the first minute to heat the gas in the tube to produce bright light. During this time, the light may appear dim or even flicker before reaching full brightness.
-
Instant Performance: LED lamps typically do not provide instant performance when turned on. This can be a problem in situations where you need instant light, such as in a room that is frequently turned on and off.
LED (Light Emitting Diode) lights:
-
Warm-up Time: One of the main advantages of LED lights is their instant performance. When you turn on an LED light, it reaches full brightness instantly with no warm-up time. There are no brightness dip or flashing phases.
-
Instant Performance: LED lights provide instant performance when turned on. This makes it especially suitable for situations where you need instant light, such as in rooms that are frequently turned on and off, or in places where sudden lighting is needed, such as outdoor lights.
With better instant performance, LED lamps are often considered more comfortable and practical in daily use compared to fluorescent lamps. Faster warm-up times also result in better energy efficiency as no energy is wasted waiting for the lamp to reach full brightness. Therefore, many people are switching to LED lamps for household and commercial use because of their better instant performance.
Quality of Light Produced by LED and LED Lamps
Quality of light produced by TL (Tubular Fluorescent Lamp) lamps and LED (Light Emitting Diode) lamps can differ in several aspects. The quality of this light can affect visual comfort, color authenticity and the atmosphere in the room. Let’s look at the comparison of the light quality of the two:
TL Lamp (Tubular Fluorescent Lamp):
-
Light Spectrum: Traditional fluorescent lamps can produce a light spectrum consisting of certain long lines in the electromagnetic spectrum. This can produce light that has a predominant blue-green tone, with a lack of red and yellow color components. This light quality is often considered cold or hazy by some people.
-
Color Ratio Index (CRI): Most fluorescent lamps have The Color Latch Index (CRI) is usually quite low. CRI is a measure of the extent to which the lamp light is able to maintain the original color of the object being illuminated. TL lamps often have a CRI below 80, which can make colors look less vivid and accurate.
-
Flicker: Some TL lamps can experience flicker. ) which may be invisible to the human eye but can interfere with visual comfort and well-being.
LED (Light Emitting Diode) lights:
-
Light Spectrum: LED lights can be designed to produce a wide spectrum of light, including a spectrum that is more comparable to natural sunlight. This means that some LED lights can provide a more natural and visually pleasing light.
-
Color Rendering Index (CRI): Many high-quality LED lights has a good CRI, often exceeding 80 or even 90. This means that the colors of objects illuminated by LED lights often look more vivid and accurate.
-
Flicker: LED lights tend to produce lower flicker or even no flicker, depending on the quality and design. This can provide better visual comfort.
The quality of light produced by high-quality LED lamps is often considered better than traditional TL lamps. This can create a more comfortable, natural lighting environment, and allow objects and colors to appear better. However, it is important to remember that not all LED lights are the same, and light quality can vary between different brands and types of LED lights. Before purchasing an LED lamp, check the product specifications and reviews to ensure that it meets your lighting needs.
Use of Mercury in TL and LED Lamps
Use of mercury in TL (Tubular Fluorescent Lamp) lamps and LED (Light Emitting Diode) lights are different and have different environmental impacts too. The following is how mercury is used in both types of lamps and how to manage them:
Tubular Fluorescent Lamp (TL):
-
Use of Mercury:Traditional fluorescent lamps contain mercury in the form of gas or vapor. This mercury is needed in fluorescent lamps to start the light emission process. When an electric current flows through the lamp’s glass tube, the mercury evaporates and helps produce ultraviolet (UV) radiation, which then interacts with the phosphor coating inside the tube to produce visible light.
-
Mercury Management: The presence of mercury in fluorescent lamps is a serious environmental problem. Mercury is a toxic substance that can contaminate soil and water if fluorescent lamps are disposed of incorrectly. Therefore, fluorescent lamps containing mercury must be recycled specifically and must not be thrown into regular trash. Many countries and regions have recycling programs that allow the safe disposal of fluorescent lamps containing mercury.
LED (Light Emitting Diode) lamps:
-
Use of Mercury: LED lights do not contain mercury. This is one of the main advantages of LED lamps in terms of environmental safety. LED lamps produce light using semiconductors without the need for mercury.
-
Waste Management: Because they do not contain mercury, LED lamps have ecological advantages in terms of waste management. They do not pollute the environment with mercury if thrown away. However, LED lights still contain various electronic materials and components, so they are best recycled to minimize environmental impact. In some cases, the electronic components in LED lamps can even be recovered and reused in production.
Overall, LED lamps are considered more environmentally friendly than fluorescent lamps because they do not contain mercury and produces more energy efficient light. However, it is important to always ensure that LED lamps that are no longer in use or are damaged are properly recycled, such as by following a recycling program available in your area, to reduce environmental impact.
