Light Bulb Color Temperature Chart
Light Bulb Color Temperature Chart – Color temperature is a way of describing the light appearance of a bulb It is measured in degrees Kelvin (K) on a scale of 1,000 to 10,000.
Generally, Kelvin temperatures fall on the 2000K to 6500K scale for commercial and residential lighting applications.
Light Bulb Color Temperature Chart
The color temperature of a bulb tells us how the light produced will look and feel The color temperature of a light bulb is assigned based on a composite color temperature (CCT).
The Ultimate Lighting Guide: Everything You Ever Wanted To Know (and T
For example, if you heat a metal object, the object will appear shiny Depending on the Kelvin temperature at which the metal object is heated, the glow will be different colors such as orange, yellow or blue. The color temperature of the bulbs is intended to replicate the Kelvin temperature of the metal object.
Understanding the Kelvin temperature (K) makes it easier to choose lighting that makes you look and feel better. At the lower end of the scale, 2000K to 3000K, the light produced is called “warm white” and appears orange to yellow-white.
Color temperatures between 3100K and 4500K are called “cool white” or “bright white”. Bulbs in this range will emit a more neutral white light and may have a slight blue tint
A light color temperature of over 4500K brings us to “daylight”. Bulbs with a color temperature of 4500K and above will emit a blue-white light that mimics daylight.
How To Optimize Your Home Lighting Design Based On Color Temperature
Along with this ability to simulate any time of day, the temperature of light can have a significant effect on an individual’s mood and should be carefully considered. How does light temperature apply to your home or workplace? We describe it below:
This is probably the light you are most familiar with in a residential or restaurant application A warm light with a low color temperature is reminiscent of a sunset or the glow of a fire Common applications would be:
Accommodations are designed for comfort In addition, we often spend in our living room in the evening or after work, which means that you will use artificial light sources to achieve the right atmosphere of the room. It calls for warm and friendly light, so look for a light source around 2700K
For the most part, restaurants want to create an inviting and intimate atmosphere For this reason, they usually choose warm light sources with dimmers, so they can adjust the lighting after the sun goes down and day turns to night. Some will also choose a warmer color temperature to mimic daylight
How Light Bulb Temperatures Affect Paint Colours: Kelvins
A hotel’s main role is to make you feel at home, so it’s no surprise to see them use the same color temperature that you might use in your living room or restaurant. Great choice for hospitality
If you still want a quiet environment but need some brightness in your surroundings, go up to 3000K. These light levels are for residential areas, but are usually used where you are working, such as kitchens and bathrooms. Here are some common applications of 3000K lighting:
The bathroom is one of those places in your home where you can go with hot or cold temperatures depending on your preference. You want to go a little further than your living room so you can see what you’re doing and a bright reflection in the mirror. You don’t want to miss that poppy seed stuck in your teeth! That’s why we recommend 3000K in the bathroom
While the kitchen is a gathering place in your home that justifies warm color temperatures, it’s also a workshop for your culinary talents. A color temperature that isn’t as hot as the living room helps you see the true color of the food in front of you or be safer when cutting or handling food. This also helps ensure that when you take it out of the oven
Light Color Temperature Scale Bell Lighting
Circadian light theory tells us that the brain is most alert during the middle of the day when light levels shift to the pure white part of the spectrum. Therefore, we use this color temperature in environments where people need to pay attention and be alert However, spending your entire work day in all white light is often overkill, so these neutral tones should lean a little more towards the warm side, closer to the white part of the spectrum. Here are some common applications of 3500K lighting
Keep your employees alert but relaxed with this neutral warm color temperature of around 3500K. The light will be white enough to keep them from falling asleep without torturing them under blue light all day, which can cause fatigue and irritability.
Retail stores aim to create a welcoming environment on the warm side of the scale, allowing customers to see the true features of a product, such as clothing or jewelry. 3500K is usually ideal, giving you a clean, clear light that won’t be too blue and therefore not too flattering or inviting to your customers.
Sometimes a warm and cozy environment is not suitable for working Cool white light is ideal when you need precision and the ability to see your subject clearly This color temperature will be over 4100K Here are some common applications:
What Is Color Temperature?
If you are using the garage as a work area, you will want to use clear lighting This will bring clarity and create a safer work environment in any project you are working on
Compared to a clothing retail store, grocery stores typically choose a slightly higher color temperature. It creates a better environment for testing food and highlights the colors, which makes the packaging more attractive
The 5000K color temperature approaches the intensity and brightness of sunlight and is best used in professional settings where accuracy is required. These applications are as wide as sports stadiums and warehouses Here are some common applications of 5000K lighting:
Adequate lighting in the warehouse contributes to employee efficiency and productivity OSHA regulations also require adequate light levels and white light is ideal This is not the best area to use warm, pleasant lighting Warehouses need the brightest light they can afford
Full Spectrum Light Without Expensive Full Spectrum Bulbs
Sports stadiums across the country are replacing their lighting with LED technology High-definition broadcasting is now almost standard, and this clarity depends on high-quality lighting HD cameras will be able to capture fine details better when the light is white and strong
Perfect lighting is another essential industry in healthcare When you’re on the operating table, your doctor will want a strong, bright light, so he can make accurate observations and see exactly what he’s doing.
6500K light is powerful and bright You don’t want to work under such light all day, but for some applications it can be critical This type of light looks like a mixture of blue and white light and gives off a lot of energy A common application is indoor cultivation:
Light in the 6500K range appears too blue Light at this color temperature is similar to sunlight So it is most suitable for agriculture and especially for indoor agriculture CCT or composite color temperature is used to determine the color of white light sources They are measured in units, Kelvin (K), and light sources are available on the market from 1800K to 6500K.
Best Daylight Bulbs For Artists (tips And Guide)
An 1800K light source is very warm, or orange/amber They are commonly used in hospitality settings where a dark and intimate feel is desired At the other end of the spectrum, 6500K sources are very cool or blue They are usually used in a hospital or school where visual acuity is important In the middle, the 4000K source looks very white
Enhanced sources are found in the warmer part of the spectrum and are slightly yellow in color These usually fall around 2700K Halogens are still considered warmer, but have a slightly warmer CCT around 3000K. These resources are commonly found in homes, retail, hospitality and museums Most people find warm light areas the most comfortable and relaxing
A unique aspect of incandescents and halogens is that as they darken, the color temperature drops from yellow to amber to orange. Often, restaurants dim their incandescent lights at night, leaving only a warm orange glow from the chandelier. Non-incandescent sources will generally be the same shade as the dimmer
Fluorescent light sources have different color temperatures That is, without phosphors, fluorescence would only produce ultra-violet light that our eyes cannot perceive. Different amounts of different phosphors produce different colors Fluorescents are often used in areas where the lights are on continuously for long periods of time, as they are more efficient than incandescents. Office buildings, schools and hospitals often use fluorescent lights
