What is CRI?

CRI is a measurement of how accurately a light source reveals the true colors of objects compared to a natural light source like the sun. Think of it as a quality score for light. The scale ranges from 0 to 100.

• CRI of 100: This is the highest possible score, representing perfect color accuracy. The sun has a CRI of 100.

• CRI of 80 and above: This is generally considered a good CRI for residential and commercial use. Colors will look vibrant and true.

• CRI of 70 and below: Light sources in this range can make colors appear dull, washed out, or even distorted. You might notice this with older fluorescent or some low-quality LED bulbs.

Why does CRI matter?

A high CRI is crucial for tasks where color accuracy is important. For instance, in a kitchen, a high CRI bulb will make food look more appetizing. In an art studio or retail store, it ensures that products and artwork are shown in their true colors. For everyday living spaces, a high CRI creates a more pleasant and natural-looking environment.

What is Color Temperature?

Color Temperature, measured in Kelvin (K), describes the "warmth" or "coolness" of the light's appearance. It has nothing to do with the bulb's actual heat! The Kelvin scale is counterintuitive: lower numbers mean a warmer, yellower light, while higher numbers indicate a cooler, bluer light.

• Warm White (2000K - 3000K): This light is soft, cozy, and often has a yellowish or amber tint, similar to a traditional incandescent bulb. It's perfect for creating a relaxing atmosphere in bedrooms and living rooms.

• Cool White / Neutral White (3100K - 4500K): This is a balanced, clean white light. It's often used in kitchens, bathrooms, and offices where a brighter, more focused light is needed for tasks.

• Daylight (4600K - 6500K): This light has a bluish-white tint, similar to natural daylight on a clear day. It can be invigorating and is ideal for workshops, garages, and basements.

Why does Color Temperature matter?

The right color temperature can drastically change the mood and functionality of a room. Warm light promotes relaxation and comfort, while cool light enhances focus and alertness. By choosing the right color temperature, you can tailor your lighting to the purpose of each space in your home.

Bringing it all together

Choosing a light fixture isn't just about wattage anymore. By considering both CRI and Color Temperature, you can select the perfect light for any situation.

• For task lighting (kitchens, home offices): Look for a high CRI (85+) to ensure color accuracy and a cool white or daylight color temperature to promote alertness.

• For ambient lighting (bedrooms, living rooms): A high CRI (80+) is still great for making colors pop, and a warm white color temperature will create a cozy and inviting atmosphere.

The next time you're shopping for lighting fixtures, take a moment to check the packaging. You'll often find both the CRI and Kelvin ratings listed. By paying attention to these two numbers, you're not just buying a light bulb—you're curating the perfect visual experience for your home.
