It is important to understand these differences in the various contexts of use of yellow and white lights in order to use it correctly as needed. Yellow lights are usually used for warning and softer lighting, while white lights are used for brighter and functional lighting.

To understand more about the differences between yellow and white lights. So you can read a more detailed explanation regarding the differences between yellow and white lights below.

Quality of Light Produced by yellow and white lights

The quality of light produced by yellow and white lights differs in terms of color temperature, intensity, and color perception. The following is a more detailed explanation of the light qualities of both:

1. Yellow Light:

   • Color Temperature: Yellow light has a lower color temperature compared to light white. They tend to produce warmer light with a color temperature of around 2700-3000 Kelvin. This warmer light tends to create a more comfortable atmosphere and is suitable for lighting in more relaxed rooms such as the living room or bedroom.
   • Intensity: Yellow lights generally have a lower intensity than white lights. They tend to provide softer, less bright lighting.
   • Color Perception: Yellow lights tend to make objects look more yellow or golden yellow. This can affect the perception of the color of objects in yellow lighting.

2. White Light:

   • Color Temperature: White light has a color temperature which is higher than the yellow light. They often have a color temperature between 4000 to 6500 Kelvin. White lights with a higher color temperature tend to produce brighter light and have a cooler appearance.
   • Intensity: White lights have a higher intensity compared to yellow lights. They provide brighter and more functional lighting.

Energy Efficiency and Electricity Use of yellow and white lights

Energy efficiency and electricity use of yellow and white lights depends on the type of lighting technology used. Below, I will discuss the efficiency and electricity use of yellow and white lights using two common light technologies, namely incandescent lights and LED lights:

1. Incandescent Lamps:

• Yellow Incandescent Lamps: Yellow incandescent lamps have relatively low energy efficiency. They produce a lot of heat in addition to light, which makes them less efficient. Most of the energy used by incandescent lamps is converted into heat, not light, so they consume more electricity to provide the same lighting as LED lamps.
• Incandescent White Lamps: Incandescent lamps White also has low energy efficiency and consumes more electricity compared to white LED lights.

2. LED Lights:

• Yellow LED Lights: Yellow LED lights have much higher energy efficiency than yellow incandescent lights. They produce light with less heat, thus consuming less energy. Yellow LED lights also have a longer lifespan than incandescent lights.
• White LED Lights: White LED lights are one of the most energy efficient. They produce bright light with very low power consumption. In addition, white LED lights have a wide range of adjustable color temperatures, which allows you to choose the brightness and color levels according to your needs.

In general, LED lights are more energy efficient and have a longer lifespan. Lasts longer than incandescent lamps. Therefore, the use of LED lights, both yellow and white, can help reduce your electricity consumption and energy costs.

In addition, many countries and regions have moved to regulations that limit the use of traditional incandescent lamps for reasons energy efficiency. Therefore, a better choice in terms of energy efficiency is to use LED lights. This is not only better for the environment but can also save money in the long run through reduced electricity costs.

Effect on Eye Health and Sleep Quality of yellow and white lights

Light used in lighting , including yellow and white lights, can affect a person’s eye health and sleep quality. Here’s how they affect eye health and sleep quality:

Yellow Light:

1. Effect on Eye Health:

   • Eye Comfort: Yellow light is often considered more comfortable for the eyes, especially in night lighting situations. This is because yellow creates a warmer atmosphere and is less irritating to the eyes than bright lighting.
   • Blue Light Reduction: Yellow lights usually have some blue light in their spectrum. This may help reduce eye strain associated with exposure to blue light, especially at night.

2. Effect on Sleep Quality:

   • Improves Sleep Quality: Yellow light, especially when used before bed, can help stimulate the production of the hormone melatonin, which regulates the sleep cycle. This can help improve sleep quality and make it easier to fall asleep.
   • Increased Comfort: Yellow lighting tends to create a more comfortable and relaxing sleep environment, which can help a person sleep better.

White Light:

1. Effect on Eye Health:

   • Blue Light Exposure: White lights often have more blue light in their spectrum than yellow lights. Long-term exposure to high levels of blue light can cause eye fatigue and eye strain, especially if used for too long.

2. Effect on Sleep Quality:
