Let’s compare the advantages and disadvantages of these two types of incandescent or LED lights with Kim Sang to better understand.Hope this information will help you.

Definition of Incandescent Lights and LED Lights.

What is an Incandescent Lights?

An incandescent lights, also known as a filament lights, emits light when its internal filament is heated. It is encased in a transparent glass bulb that is large enough to withstand the high temperatures generated during operation without breaking.

What is the LED lights ?

LED lights (light-emitting diode lights) is an electric light used in lighting fixtures that produces light using one or more light-emitting diodes (LEDs). LED lights have a significantly longer lifespan than equivalent incandescent lights and are more efficient than most fluorescent lights.

Currently, LED lights are extremely widespread. You can easily encounter them everywhere, from store advertising signs to decorative accessories in homes. However, the true definition of this type of lamp remains unfamiliar to many people.

Comparison of Incandescent and LED Lights

Comparison of Color Temperature (CCT) between Incandescent and LED Lights

Color temperature is a technical parameter characteristic of different types of light. This parameter indicates the color of the emitted light. Each functional area in a house is suitable for a specific range of color temperatures. Therefore, when choosing bulbs for use, you need to pay attention to this factor.

When lit:

• Incandescent lights have a color temperature of 2,200K.
• LED lights have a color temperature ranging from 2,700K to 10,000K.

It can be seen that LED lights possess the most diverse color range. Incandescent lights, with their limited color range, can only emit yellow light. Therefore, when compared in terms of color temperature, LED lights definitely have the advantage.

Comparison of Color Rendering Index (CRI) of Incandescent, Fluorescent and LED Lights.

The Color Rendering Index (CRI) is a measure of how accurately a light source reveals the true colors of objects it illuminates. A low CRI means the light will inaccurately reflect the colors of the object being illuminated.

The specific CRI values of incandescent and LED lights are:

• Incandescent lights: 65 to 95 Ra.
• LED lights: 95 to 100 Ra.

Thus, LED lights can most accurately reflect the true colors of objects. They not only provide uniform lighting but also protect the viewer’s eyes according to European standards.

Comparison of Durability between Incandescent and LED Lights

Durability is an essential criterion when choosing household items. High durability helps save costs on replacements and repairs.

To determine which of the two types of lights is the most durable, we look at their lifespans. Specifically:

• Incandescent lights have a lifespan of 1,000 to 1,200 hours.
• LED lights have an average lifespan of 30,000 hours, or up to 50,000 hours.

Based on the above information, it is evident that LED lights possess the most formidable durability. When converted to years, the lifespan of LED lights can extend up to 15 years.

Comparison of Luminous Efficacy between Incandescent and LED lights

Luminous efficacy (or luminous efficiency) is a measure that indicates the quality of light and the energy-saving capability of any artificial light source.

High luminous efficacy means the light source has a high luminous flux with a low power consumption.

• Incandescent lights have a low luminous efficacy, only ranging from 10 to 20 lm/W.
• LED lights have a high luminous efficacy, ranging from 80 lm/W to 150 lm/W.

From these parameter, we can see that LED lights are the best at converting electrical energy into light energy. This characteristic makes LED lights widely popular in the market today.

Comparison of Safety between Incandescent and LED Lights.

To help you easily choose a suitable light for your family, Kim Sang has compared the safety of the two popular types of lightss: incandescent and LED.

• Incandescent lights emit infrared rays when lit. Therefore, the heat they are generating is operating at a quite high, potentially causing burns if accidentally touched.
• LED lights do not emit any harmful rays when lit. They also do not contain toxic substances that could harm the environment and your family’s health.
