Compare Fluorescent Lights and LED Lights

Compare Fluorescent Lights and LED Lights are two lighting devices commonly used in homes, shops, cafes,… In this article, Kim Sang will help you compare these two types of lights in detail.

1. What is the Fluorescent Lights?

Fluorescent lights commonly referred to as a tube light or fluorescent tube, consists of electrodes and a bulb coated with a layer of phosphor powder (mainly composed of phosphorus compounds). Additionally, a small amount of  mercury vapor and inert gases (such as neon, argon, etc.) is injected into the bulb to increase the durability of the electrodes and produce colored light.

The structure includes:

• Glass tube: Length ranges from 0.3m to 2.4m, with the inner surface coated with phosphor powder, containing mercury vapor and inert gases (neon, argon, etc.).

• Electrode: Made of tungsten wire, in a twisted coil shape, connected to the outside through the bulbs base.

Characteristics of fluorescent tube lights: flickering phenomenon, higher luminous efficiency than incandescent lamps, lifespan of 8000 hours, and requires an electric starter.

2. What is the Led lights?

Led lights are the electric light used in lighting fixtures, producing light by using one or more light-emitting diodes (LEDs). LED lights have a significantly longer lifespan than equivalent incandescent bulbs and are more efficient than most fluorescent lights.

 3. Similarities between Fluorescent Lights and LED Lights:

• Both LED lights and fluorescent lights are currently available on the market as lighting devices.
• Fluorescent lights and LED lights can be used for residential, office, outdoor, and industrial lighting,…
• Both types of lights are simple and easy to install and use.
• LED lights and fluorescent lights emit light that does not negatively impact human health.

Different:

• Fluorescent lights are composed of fluorescent powder that acts as the luminescent material. The light illuminates when an electric current passes through the filament, causing electron radiation to interact with the noble gases in the fluorescent tube, generating ultraviolet rays. These ultraviolet rays then excite the fluorescent powder, causing the light to glow.
• LED lights utilize the most modern and advanced LED technology available today. The lights illuminate when an electric current from the LED driver is supplied to the LED chip. LED lights often use high-quality LED chips from renowned brands.

 4. Lumen of Fluorescent lights compared to LED lights

• LED lights have high lumen, providing illumination for large spaces.
• Fluorescent lights have average lumen, illuminating a smaller area compared to LED lights.
• LED lights have a lumen depreciation of 6%, whereas fluorescent lights have a depreciation of 20%.

5. Compare the brightness of LED lights and Fluorescent lights

 Reviews

• LED lights have high luminous efficiency, provide good illumination, and are more energy-efficient compared to fluorescent lights.
• The quality of light offers more accurate color rendering than fluorescent lights.
• Using LED lights results in optimal performance and significant electricity cost savings for users.

6. Compare the power of LED lights and Fluorescent lights

Comparison

The power of Fluorescent lights

• Fluorescent lights typically have a higher wattage than LED lights. There are various types of fluorescent lights: compact fluorescent lamps (CFLs), 1.2-meter fluorescent tubes, neon lights, etc.
• Some common wattages for fluorescent lights include 15W, 20W, 24W, 40W, and 50W.

Fluorescent lighting efficiency

• The average luminous efficacy of fluorescent lights ranges from 62 to 70 lm/W. This is considered a moderate level of efficiency, offering better energy savings compared to incandescent bulbs.
• However, when compared to LED lights, fluorescent lights still have a lower luminous efficacy and consume more energy.

Compare the power of LED lights with Fluorescent lights

• Due to different production technologies, LED lights and fluorescent lights vary in lighting efficiency for each wattage.
• Specifically, when using fluorescent lights of a certain wattage, users can replace them with lower-wattage LED lights while still ensuring adequate illumination, thereby saving energy.

Assess the brightness of fluorescent lights

• LED lights have a luminescent efficiency 3 times higher than fluorescent lights.
• Therefore, in the same lighting area, if the user chooses a fluorescent lights, it will require more power than an LED lights.
• When using LED lights will help users save energy better than fluorescent lights.
• Thus, using LED lights is always more appreciated due to its ability to save money and save monthly electricity costs for users.

 7. Compare of LED lights and Fluorescent lights

 Comparison

Tube Led light 1m2

• Led Tube is a type of tube with length = 1200mm (1m2). This is the most common and commonly used size.
• Some wattage equivalent to 1200mm length of LED tube is: 18w, 20w, 25w.

Fluorescent lights 1m2

• The 1.2-meter fluorescent tube light was the most commonly used type of light before LED lights became available. Its design is quite similar to that of LED lights, but it has lower efficiency and a poorer color rendering index.
• Some common wattages include 20W, 24W, and 40W.

8. Compare the specifications of Fluorescent lights and LED lights

• LED tube lights and fluorescent lights both have similar designs.
• However, each type is manufactured using different technologies, resulting in varying performance characteristics.
• Users can refer to the comparison table between LED tube lights and fluorescent lights to gain a better understanding of these lighting options. This will help in selecting the appropriate lighting device based on their specific requirements.

9. Should fluorescent lights be replaced with LED lights?

Compare the electricity saving ability of 1m2 Fluorescent lights with LED lights.

• By comparing fluorescent lights with LED lights, it is evident that using LED lights can save up to 60% on monthly electricity bills.
• LED lights are the optimal cost-saving solution for monthly and annual lighting expenses for households and businesses alike.

You should replace fluorescent lights with LED lights to save electricity

• After comparing the metrics between fluorescent lights and LED lights or LED tube lights, buyers can clearly see that LED lights are currently the most superior lighting devices.
• Using LED lights provides high illumination efficiency for large spaces and saves energy.

• LED lights also have a long lifespan of over 40,000 hours, good durability, and are user-friendly.
• Using LED lights for illumination will yield good results, increase work productivity, and save on electricity bills, maintenance, and replacement costs. Therefore, buyers can use LED lights or LED tube lights to replace fluorescent lights to achieve high economic value.
• Choose products from reputable brands to avoid flickering LED lights during use.
