Will it appear too blue? We don't think so - it is definitely a more intense, white color, but not a harsh, blue color. During evening hours, if you walk from your 3000K living room lighting into the 4000K kitchen, things will definitely appear whiter and crisper.
Let's say you're considering 4000K for your home kitchen area. What this means is that depending on what your eyes have adapted to, its appearance can differ. The human vision system has an impressive way to adapt to ambient lighting conditions. Will 4000K Appear Too Blue? Will 4000K Appear Too Yellow? A high CRI value of 95 or higher typically ensures that the light spectrum does indeed replicate a natural light spectrum.

If you are looking for an LED light to perform color-critical tasks, or are looking for full spectrum lighting for a health-related application, you will need to look at the LED bulb's color rendering index (CRI) value to get a better sense of the spectral similarity. During mid-day hours, direct sunlight will have a color temperature over 5000K, and daylight (including the entire blue sky) will have a color temperature closer to 6500K.įinally, just because an LED bulb emits a color that looks like natural daylight, does not mean that it has the same light spectrum as natural daylight.

In general, the more red/orange the sky is (morning or afternoon light), the lower the color temperature, and the more blue the sky is (mid-day daylight, or windows facing away from the sun), the higher the color temperature.Īs such, you will find that the color appearance of a 4000K LED bulb is similar to natural sunlight during morning or afternoon hours. The reason for this, is that the sun itself has a constant color temperature of approximately 5800K, but depending on how the color of the sky, the color temperature of natural daylight can change significantly.

Is 4000K Similar to Natural Daylight?Ĭomparing LED bulbs to natural daylight a bit tricky, because natural daylight itself is always changing, depending on the weather, time of day, season and latitude. (Of course, one of the best ways to answer this question is to see a 4000K light source in person. This makes 4000K a popular choice for customers looking for a bit more clarity and crispness in their light, but also don't want something too blue or stark.
It is also the color temperature of direct sunlight during morning or afternoon hours. You are most likely to encounter 4000K color temperatures in retail and office spaces. What Does 4000K Look Like?Ĥ000K is an often overlooked color temperature, as it falls right in between "warm white" (2700K/3000K) and "daylight white" (5000K/6500K) color options.Īs one would expect, is most definitely on the "cool" side when compared to typical warm white lighting options, but is also on the "warm" side when compared to daylight color temperatures. In this article, we'll go over the 4000K color temperature option, and help you determine if that is the best color choice for you. If you want to make an educated decision when purchasing LED bulbs, you'll want to get a bit more technical, and know exactly which color you're getting! In reality, these names can refer to a wide range of color temperature options, including 4000K, 5000K and 6500K. Then, there's a jumble of names ranging from "neutral white," "bright white," "daylight" and "cool white." You might be tempted to think they're all the same, or close enough. For most residential installations, especially bedrooms and living room areas, these color temperatures will work well. When shopping for LED bulbs, you'll come across "warm white" or "soft white" bulbs, which typically have a color temperature rating of 2700K or 3000K.
