LED technology is constantly evolving, resulting in a continuous decrease of costs and a global trend towards energy savings and emission reduction. More and more LED lamps are being adopted by customers and projects, from home decoration to municipal engineering construction. Customers tend to focus on the cost of the lamp, not the quality of the power supply or LED chips. They often neglect the importance of color temperature and the various uses of LED lamps. The right color temperature for LED lamps can enhance the project's texture and make the lighting environment more affordable.
What’s color temperature?
The color temperature is the temperature at which the black body appears after it has been heated to absolute zero (-273degC). The black body gradually changes from black to red when heated. It then turns yellow and turns white before finally emitting blue light. The temperature at which the black body emits light is known as the color temperature. It is measured in units of "K" (Kelvin). It is simply the various colors of light.
The color temperatures of common light sources:
High pressure sodium lamp 1950K-2250K
Candle light 2000K
Tungsten lamp 2700K
Incandescent lamp 2800K
Halogen lamp 3000K
High-pressure mercury lamp 3450K-3750K
Afternoon daylight 4000K
Metal halide lamp 4000K-4600K
Summer noon sun 5500K
Fluorescent lamp 2500K-5000K
CFL 6000-6500K
Cloudy day 6500-7500K
Clear sky 8000-8500K
The majority of LED lamps currently on the market fall within the three following color temperatures. Each color has its own characteristics:
Low color temperature.
Below 3500K the color is reddish. This gives people a warm, stable feeling. Red objects can be made more vivid by using low-color temperature LED lamps. It is used to relax and rest in leisure areas.
Moderate color temperature.
The color temperature ranges from 3500-5000K. The light, also known as neutral temperature, is soft and gives people a pleasant, refreshing and clean feeling. It also reflects the object's color.
High color temperature.
Cold light is also known as bluish bright, calm, cool and bright. It has a color temperature of above 5000K. This can cause people to concentrate. It is not recommended for families but can be used in hospitals and offices that require concentration. However, high-color temperature light sources have a higher luminous efficiency than lower color temperature sources.
We need to know the relationship between sunlight, color temperature, and daily life. This can often impact the color of our lamp colors.
Natural light sources at dusk and daytime have a lower color temperature. The human brain is more active under high-color temperature lighting, but less so when it is dark.
Indoor LED lights are often selected based on the mentioned relationship and different uses:
Residential area
Living room: This is the most important area in the home. It has a neutral temperature of 4000-4500K. The light is soft and gives people a refreshing, natural, unrestrained, and pleasant feeling. Especially for European markets, most magnetic rail lights are between 4000 and 4500K. It can be matched with yellow table and floor lamps to add warmth and depth to the living space.
Bedroom: The bedroom is the most important area of the home and should be kept at a temperature around 3000K. This will allow people to feel relaxed, warm, and fall asleep faster.
Kitchen: Led lights with a color temperature of 6000-6500K are commonly used in the kitchen. Knives are commonly used in the kitchen. The kitchen led light should allow people to concentrate and avoid accidents. White light is able to make the kitchen look brighter and cleaner.
Dining Room: This room is suitable for low-color temperature LED lamps with reddish tones. Low color temperatures can increase color saturation which can help people eat more. Modern linear pendant lighting is possible.
Bathroom: This is a relaxing space. It is not recommended to use a high color temperature. It can be used with 3000K warm or 4000-4500K neutral lighting. It is also recommended to use waterproof lamps, such as waterproof downlights, in bathrooms, to avoid water vapor eroding the internal led chips.
Interior decoration can be greatly enhanced by the correct use of white light temperature. It is important to use the right color temperature lighting for your decoration colors in order to maintain the highest quality lighting. Consider the color temperature of indoor walls, floors and furniture as well as the purpose of the space. The blue light hazard caused by the light source must also be considered. Low color temperature lighting is recommended for children and the elderly.
Commercial area
Indoor commercial areas include hotels, offices, schools, restaurants, supermarkets, shopping malls, underground parking lots, etc.
Offices: 6000K to 6500K cold white. It is difficult to fall asleep at 6000K color temperature, but it can be a great way to boost productivity and invigorate employees. Most led panel lights in offices use 6000-6500K colors.
Supermarkets: 3000K+4500K+6500K mix color temperature. There are different areas in the supermarket. Each area has a different color temperature. The meat area can use 3000K low temperature color to make it more vibrant. For fresh food, 6500K color temperature track lighting is best. The reflection of crushed ice can make seafood products appear fresher.
Underground parking lots: The 6000-6500K are the best. The 6000K color temperature is a good choice to help people focus and make driving safer.
School classrooms: 4500K color temperature lamps can illuminate the comfort and illumination of classrooms while avoiding the disadvantages of 6500K color changes that will cause students' visual fatigue and an increase in brain fatigue.
Hospitals: 4000-4500K for recommendation . In the recuperation area, patients are obliged to stabilize their sentiments. A tranquil lighting setup will help enhance their happiness; the medical staff develops focus and discipline, and uses an effective lighting program that enhances their involvement. Therefore, it is highly recommended to use lighting fixtures that provide good color rendition, a high illumination, and a mid-range color temperature between 4000 and 4500 K.
Hotels: A hotel is a place where various travelers can relax and rest. Regardless of the star rating, the atmosphere should be friendly and conducive to relaxing, so as to emphasize comfort and friendliness. Hotel lighting fixtures should use warm colors to express their needs in the illumination environment, and the color temperature should be 3000K. Warm colors are closely related to emotional activities such as kindness, warmth, and friendliness. Transitioning spotlight lamp wall washer with a 3000k warm white bulb is popular in commerce.
Industrial area
Industrial industries are places with a lot of work, such as factories and warehouses. Industrial lighting generally includes two kinds of lighting-regular lighting for emergency illumination.
Workshop 6000-6500K
The workshop has a large illuminated workspace and a 6000-6500K color temperature requirement for optimal illumination. As a result, the 6000-6500K color temperature lamp is the best, able to not only meet the maximum illumination requirements but also make people focus on work.
Warehouse 4000-6500K
Warehouses are usually used for warehousing and for keeping products, as well as gathering, capturing, and counting them. The optimal temperature range for 4000-4500K or 6000-6500K is appropriate.
Emergency area 6000-6500K
An industrial zone typically needs emergency lighting to assist personnel during an emergency evacuation. It can also come in handy when there is a power outage, since staff can continue to do their work even during the crisis.
Outdoor lamps including floodlights, streetlights, landscape lighting, and other outdoor lamps have strict guidelines concerning the color temperature of the light.
Street lamps are important parts of urban lighting. Choosing different color temperatures will affect drivers in different ways. We should pay attention to this lighting.
2000-3000K appears yellow or warm white. It is the most effective at penetrating water on rainy days. It has the lowest brightness.
4000-4500k It is close to natural light and the light is relatively dim, which can provide more brightness while still keeping the driver's eye on the road.
The highest brightness level is 6000-6500K. It can cause visual fatigue and is considered the most dangerous. This can be very dangerous for drivers.
The most appropriate street lamp color temperature is 2000-3000K warm white or 4000-4500K natural white. This is the most common street light source available (metal halide lamp temperature 4000-4600K Natural White and high-pressure sodium lamp temperature 2000K Warm White). The 2000-3000K temperature is the most commonly used for rainy or foggy conditions. A color temperature between 4000-4500K works best for road projects in other regions. Many people chose 6000-6500K coldwhite as their primary choice when they first started to use LED street lights. Customers often seek high light efficiency and brightening. We are a professional manufacturer of LED street lights and have to remind our customers about the color temperature of their street lights.
Floodlights are a major part of outdoor lighting. Floodlights can be used for outdoor lighting, such as squares and outdoor courts. Red light can also be used in lighting projects. The light sources are green and blue light. The stadium floodlights are the most demanding in terms of color temperature. There will likely be competitions within the stadium. It is important to remember that lighting should not have adverse effects on the players when choosing color temperature and lighting. The 4000-4500K color temperature for stadium floodlights is a good choice. It can provide moderate brightness and reduce the glare to the maximum extent.
Outdoor spotlights and pathway lights are used to light up outdoor areas such as gardens and paths. A warm 3000K color light, which looks warm, is better, as it's more relaxing.
