Traditional vs Contemporary Lighting in Kitchens

Last week, we took a look at the ergonomics in kitchen layout, spacing, sizing, and configuration.  Today we’re talking about a similar but different topic related to technological changes in lighting in the kitchen. Kitchen lights have a major impact on the overall aesthetics and functional use of a kitchen. Last week we talked about the ergonomics of spacing in the configurations of a kitchen but lighting also has a major impact on ergonomics. Good lighting can make a kitchen work well from a functional effectiveness of a space.  Particularly having sufficient light at countertops and work surface areas is very important to the productive usability of a space.  As well, having lighting that is both ample yet appropriately gentle, reduces strain on the eyes and is conducive to effective and comfortable use.

Today we’re talking about several different elements of effective lighting and tips on how kitchens can be designed with lighting in mind to make the space more effectively useful and comfortable.  

Lighting takes a central role in enhancing the human factors in use and functionality of a kitchen space. Proper lighting not only contributes to the overall aesthetics but also ensures comfortable and efficient use of the kitchen. Here are some key principles and ideas regarding ergonomic use of lighting in the kitchen:

1. Layered lighting: Incorporate different layers of lighting to create a well-lit and balanced environment. This includes: 
   1. Ambient lighting: Provides overall illumination for the entire kitchen space, typically achieved through ceiling-mounted fixtures or recessed lights. 
   2. Task lighting: Focused and bright lighting directed at work surfaces, such as countertops and cooktops, to ensure visibility and reduce eye strain during food preparation and cooking tasks. 
   3. Accent lighting: Highlights architectural features, cabinets, or artwork, adding depth and visual interest to the space.
2. Adequate task lighting: Proper task lighting is essential for ergonomic purposes. Undercabinet lighting or pendant lights positioned over work surfaces can provide focused illumination, minimizing shadows and reducing eye strain. The recommended light level for task lighting in the kitchen is often between 500 and 800 lux (50-80 foot-candles).
3. Lighting color and temperature: The color temperature of the light can significantly impact visual comfort and perception. Warm white light (2700K-3000K) creates a cozy and inviting atmosphere, while cool white light (4000K-5000K) is better suited for task areas as it enhances visibility and reduces eye strain.
4. Lighting placement and spacing: Proper placement and spacing of lighting fixtures are needed to achieve even illumination and reduce glare or shadows. Undercabinet lights should be spaced evenly along the length of the countertop, typically 12-18 inches apart. Pendant lights should be positioned at a height that provides adequate clearance while illuminating the work surface effectively.
5. Dimmable lighting: Including provisiones for dimmable lighting allows for adjusting the light levels based on the task or desired ambiance. This flexibility can contribute to visual comfort and energy efficiency.  Also, in today’s world we use our kitchens for much more than just food prep a kitchen today is also a place of gathering and eating and the ability to change the light from a working ergonomic type of lighting to a more cozy and or romantic atmosphere for dining or even having a glass of wine, can be extremely useful.
6. Glare reduction: Minimize glare from light sources by using diffusers, shades, or positioning fixtures correctly. Glare can cause eye strain and discomfort, hampering ergonomic performance.
7. Lighting controls: Install lighting controls, such as dimmers, motion sensors, or programmable systems, to easily adjust the lighting levels and settings based on the time of day or specific tasks.  (In a future article, this coming week though, we will talk about a particular common mistake in modern kitchen design: to ineffectively over-gadgetization.)

By incorporating these principles into the kitchen lighting design, you can create an ergonomic and visually appealing environment that facilitates efficient and comfortable use of the space. Proper lighting not only enhances the overall functionality but also contributes to the well-being and productivity of the individuals using the kitchen.

The picture and chart below shows several different highlights from today’s article and how it can affect the design, layout, and usability of a kitchen space.

Traditional lighting options commonly used in kitchens included incandescent bulbs and linear fluorescent tubes. Incandescent bulbs emit a warm, yellowish light by heating a filament inside the bulb, creating a cozy ambiance but with relatively low energy efficiency. Linear fluorescent tubes, on the other hand, produce light through an electrical discharge in a gas-filled tube, offering improved energy efficiency but often with a cooler, harsher light quality.

Modern lighting alternatives, such as LED (Light-Emitting Diode) and compact fluorescent lamps (CFLs), have revolutionized kitchen lighting. LED lights are highly energy-efficient, long-lasting, and available in a wide range of color temperatures, from warm to cool white. They also offer directional lighting capabilities, making them ideal for task lighting and undercabinet installations. CFLs, while more energy-efficient than incandescent bulbs, have been largely replaced by LEDs due to their superior performance and versatility.

The color temperature of lighting plays a crucial role in creating a comfortable and functional environment, especially in the kitchen. It is measured in Kelvin (K), with lower values producing warmer, reddish tones and higher values producing cooler, bluish tones. The appropriate color temperature can influence circadian rhythms, the natural sleep-wake cycle regulated by the body’s internal clock.

Lighting with a higher color temperature, around 5000K-6500K, mimics the cool, bluish hues of natural daylight. This type of light can help promote alertness and productivity, making it suitable for task areas and morning use in the kitchen. Cooler light temperatures have been shown to suppress melatonin production, the hormone responsible for inducing sleepiness.

Conversely, lighting with a lower color temperature, around 2700K-3000K, emits a warmer, reddish-orange glow similar to candlelight or sunset. This type of light is often preferred for creating a cozy and relaxing atmosphere in the evening or dining areas. Warmer light temperatures encourage melatonin production, promoting a restful state and preparing the body for sleep.

By incorporating lighting with adjustable color temperatures or utilizing separate circuits for task and ambient lighting, homeowners can tailor the kitchen’s lighting to support their circadian rhythms. Bright, cool-toned lighting in the morning can help kickstart the day, while warm, dimmed lighting in the evening can signal the body to wind down and prepare for restful sleep.
