Warm White Or Cool White: What Is Better For Eyes?

warm white or cool white better for eyesIt’s not a secret that lighting serves more than one (and pretty obvious) function in our everyday lives. It also helps us set the right mood, create a proper ambiance and make the objects appear more vivid and attractive. Unfortunately, completely opposite things can happen if we choose the wrong lighting. Something as simple as lighting determines how we feel in a room – comfortable and relaxed, or uneasy and weary. And this is not just a matter of temporary discomfort. Some types of light are not friendly to our eyes and can even cause serious damage in a long run. So let’s find out which light sources are perfect for you and which should be avoided. And what light: warm white or cool white better for eyes?

First of all, let’s sum up everything that we know about artificial light. There are several common types of light bulbs: incandescent, fluorescent, LED, and halogen (less common). The light emitted by artificial sources has a wide range of possible color temperatures ranging from 1000 K to over 7000. Therefore, to choose the light that would be perfect for your eyes, you should consider the type of light source and the color temperature.

Warm White vs Cool White vs Daylight: A Comparative Chart

As we can see, the warm white spectrums, as well as neutral white, are the most favorable to your eyes. By choosing the right color temperature for each of your activities you can make sure that by the end of the day your eyes won’t be too tired. For instance, if you are thinking about daylight vs soft light for a living room, you should consider your typical activities. In case it’s mostly watching television and hanging out with family and friends, then soft light will be perfect. If your living room is also a work zone, then you might want to consider daylight. In any case, overhead lighting is not as important for your eyes as task lighting. That’s why you should be more concerned about finding the best reading lamp for eyes.

So which light is good for eyes: white or yellow? In fact, color temperature isn’t the only thing that affects your eyes. As we have already mentioned, there are several types of light bulbs and not all of them are good for your vision.

All Types Of Light Bulbs

  1. all types of light bulbsIncandescent bulbs produce light in the warm spectrum. Depending on wattage they can be rather bright and the light they emit can be very clean. You can find incandescent bulbs for all types of activities. Such bulbs are usually rather comfortable for eyes, but very uneconomical.
  2. Halogen bulbs. These bulbs are more long-lasting than incandescent bulbs, have a higher lumen output and the color temperature is usually higher. Even though these bulbs are applicable to a variety of indoor and outdoor lighting projects, they are losing their ground to LED lights. And you will see why.
  3. LED lights come in a variety of forms. There are replaceable LED bulbs that can go into regular sockets, and there are LED lighting fixtures with integrated diodes. LED lights are available in both warm and cool white, as well as neutral white. They are energy-efficient, long-lasting and safe for your eyes. The best floor lamps for reading are equipped with LED lighting.
  4. Fluorescent light bulbs and tubes are the sources of light that can harm your eyes and should be avoided as much as possible. The thing is that such bulbs emit UV rays, which are very bad for our eyes. As a matter of fact, fluorescent bulbs produce mostly cool white or daylight, that’s why we often associate cool light with something unhealthy. Unfortunately, fluorescent tubes are often used in commercial facilities, offices, schools, and public places, where we usually spend a lot of time.

General Conclusions and Recommendations

To sum up, there is no definite answer to the warm lighting vs cool lighting dilemma. There are tasks, for which cool light is more suitable (floor lamps for reading usually feature either neutral or cool white light). On the other hand, leisure activities and relaxation will be more enjoyable under a warm light. But you don’t need to make the “cool white vs warm white” decision once and for all. You can try different options and see what works best for you.
