Viirbright - LED Lighting By Color Temperature: Light Bulbs, Tubes

Have you ever noticed that some light bulbs give off a warm, yellowish glow, while others have a cooler, bluish tint? That difference is called color temperature, and it's measured in Kelvins (K).

When we talk about color temperature, we're basically describing how "warm" or "cool" the light looks. Warm light has a yellowish, orangey glow, while cool light has a bluish, white-ish tint. The color temperature scale ranges from 1,000 to 10,000 Kelvins, with warmer colors falling in the 1,000-5,000K range, and cooler colors ranging from 5,000K-10,000K.

But why does color temperature matter? Well, for one thing, different types of lighting are better for different tasks. For example, warm light is often used in living spaces and bedrooms because it creates a cozy, relaxing atmosphere. Cool light, on the other hand, is better for places where you need to concentrate or see things clearly, like a home office or a workbench.

Color temperature is also important in photography and videography because it can affect how colors look on camera. If the color temperature of the lighting doesn't match the natural light, it can create a weird, unflattering color cast in photos and videos.

So, where does color temperature come from? The color temperature of natural light changes throughout the day, depending on the angle of the sun. At midday, the sun's color temperature might be around 6,000K, which is very bright and bluish. At sunset, it might dip below 3,000K, creating a warm, amber light.

In artificial lighting, the color temperature is usually determined by the type of bulb or fixture being used. Incandescent bulbs, for example, give off a warm light because they work by heating a filament until it glows. LED bulbs can be designed to emit light at different color temperatures, depending on the intended use.

Overall, understanding color temperature is an important part of choosing the right lighting for a particular task or space. So, the next time you're picking out light bulbs, think about whether you want a warm, cozy glow or a cool, bright light. With a little knowledge of color temperature, you'll be able to create just the right mood in any room!
