warm, cool and neutral lighting examples

Just a couple of decades ago, choosing the right lighting for your home was as simple as heading to the local hardware store and purchasing the right size bulb for your lamp or socket. Before the advent of CFL and LED lights, there were limited options for energy-saving lighting, and almost all incandescent bulbs give off that same, warm, yellowish glow of light.

Fast forward to today and a trip through the lighting department of your local hardware store most likely offers you hundreds of different options - and infinitely more if you look online. Not only can you choose between dozens of different energy efficient bulbs, you can also opt for different colors of lighting as well.

Most CFL lights offer what is known as cool light, or white light, while LED lighting can be found in both cool and warm (yellow) light. Today, many smart LED lighting options allow homeowners to change the hues of the lights in their home with programs like the Google Home App's Color Picker".

This short article explores the differences between what is known as “warm” and “cool” lighting to help homeowners pick the best lighting option for different parts of their home. 

Differences Between Warm and Cool Lighting


When you turn on a light in your home, it probably emits either a white or yellowish glow. The white color refers to cool lighting, while warm lighting is characterized by a softer yellow hue. Correlated Color Temperature (CCT) in different lighting fixtures is used as a description of the color of the light emanating from the light fixture. CCT is measured in kelvins (K) on a 1,000 K to 10,000 K scale. Warm, yellow lighting has a CCT rating of between 2,400 and 2,700 K, while cooler, white LED lighting has a rating of 4,000 K.

So what exactly does this mean for the lights we use in our homes? In practical terms, cool lighting will contain more “blue light” and will appear slightly brighter to the eye. This is why cool or white LED bulbs are rated as having a higher lumen output than their warm LED counterparts.

Cool lighting tends to offer a more modern and “clean” look for different areas of your home while warmer, yellow lights offer a softer and more conventional “glow” for your home. It comes as no surprise that people who live in colder climates tend to prefer warm lights, while homeowners in warmer climates tend to favor cooler lighting options. 

The Effects Of Blue Light


While the decision on which type of lighting is best for your home is mostly a question of individual style preference, there are a few health considerations that should be taken into account. Cool CLF and LED bulbs have been shown to negatively affect sleeping patterns, similarly to the blue light emitted by our cell phones and computers. Not only do these cool lights produce artificial light at night, but their higher concentration of blue light can throw off your body’s circadian rhythms

A recent article in Live Science finds that “exposure to blue light suppresses the production of melatonin more than any other type of light. It is believed that the shorter wavelengths in blue light is what causes the body to produce less melatonin because the body is more sensitive to this type of light.” Suppressed melatonin levels can disrupt your sleeping patterns. At the same time, exposure to bright light during the daytime hours can boost attention, reaction times, and improve your overall mood while making it easier to fall asleep at night - when it’s dark. You must carefully consider the placement of warm lighting and cool lighting in your home, as they have the potential to negatively affect your mood if placed poorly/in inappropriate spaces.

Light Temperatures By Room


While there are no set rules for color temperature, here are some general guidelines for warm vs cool lighting in different areas of the home.

  • Warm Light for the Bedroom. Warm lighting makes much more sense for bedrooms, especially in the case of night lamps as the lower levels of blue light will not affect your sleep patterns as much. 

  • Cool Light for the Office. Now that the home office has become essential for work and school, cool light works well here for encouraging focus, alertness, and clear video conferencing!

  • Cool Light for the Kitchen. Many homeowners find that cool, white lighting is best for kitchens as it offers a feeling of cleanliness and modernity, as well as providing full illumination for cutting and cooking.

  • Warm or Cool Light for the Bathroom. Warmer lighting might also be better for bathrooms where this can offer a relaxing feel for a warm shower or hot bath. And if your bathroom already has a lot of white in it (like the tub, sink, or tiles,) a burst of bright, white light in the middle of the night or first thing in the morning can be quite a shock! Although, just like in the kitchen, cool light in the bathroom can amplify a sense of cleanliness, and provide a comfortable environment for self-care tasks that require full visibility, like shaving or applying makeup. This room is where multiple lighting options - and a generous supply of ambience-enhancing candles - may help create the ideal lighting for many situations.

  • Warm Light for the Dining Room. Warmer lighting for dining areas can bring a sense of coziness to your family dinners or dinner parties. 

Again, these are just general suggestions. Be sure to take into account the amount of sunlight each room receives, which tasks will be completed there, as well as what feels good. Your personal preference is always the most important factor to consider when making any decision in your home!
