The right light at the right time and place. It is no big surprise that light affects our mood and productivity. Productivity losses cost U.S. employers $576 billion annually. That’s a humongous number, don’t you think?

Case study:
The effects of light on health, mood, and performance in ARUP offices.

In this pilot installation, and for the first time to our knowledge, we investigate the effects that a dynamic spectrally tunable lighting system that mimics daylight has in the subjects under study compared to a traditional lighting system made of fluorescent lights. Within this work assessment of alertness, mood, sleep quality, performance, mental effort, headache, and eye strain through a 9-weeks intervention using subjective and objective measurements in offices were done.

This pilot project, prototype installation and subsequent experiment is part of the European Union’s Horizon 2020 Elliot research project: The experiment was held in ARUP London headquarter. The installation and the study was scientifically oriented and several neuroscientists were involved to build a theoretical framework concerning the interaction between the light spectral composition and human physiology.

The effects of light on health

In addition, the non-visual effects of light such as effects on mood, quality of sleep, general alertness and hormone secretion were investigated to understand the non-visual effects of different types of light (lights of different wavelengths), using our spectrally-tunable lighting technology that allows advanced control of light spectra for office workers. The scientific aim was to understand how the non-visual responses to light interact with time of day and type of work performed and to understand ultimately how these contribute to people’s everyday health, emotions and behavior. You can read more about the aims of the experiment and the methodology followed in this CIE publication.

Ledmotive in office spaces

Integrated intelligence, presence and daylight detection saves an additional 60% of energy consumption as compared to other LED systems.

Better working conditions increases employee productivity

“Today productivity costs are 112 times greater than energy costs in the workplace”
Lighting quality is comprised of a complex mix of light level and spectrum, while the interplay of light and shadow gives a space character and helps the eye to relax and focus. Poor visibility, glare, flicker and lack of control of the visual environment can all affect task performance, whilst visual discomfort may lead to headaches and eyestrain. Light is also vital for maintaining our circadian rhythm.

Overall, the evidence is unequivocal; office occupants prefer access to windows and daylight, which bring consistent benefits in terms of satisfaction and health.
Integrating quality daylighting schemes into an office space can save over $2,000 per employee per year in office costs (download full report here).

A recent study by neuroscientists suggested that office workers with daylight slept an average of 46 minutes more per night.

Ledmotive for retail

  1. High fidelity to daylight. Color perception is not altered
  2. Best CRI / R9 / CQS / GAI in the market. Just adapt the spectrum to your needs
  3. Create dynamic lighting scenes. CCT and wide gamut color reproduction and personalization
  4. Centralized lighting control over the Internet. Color assessment. Energy monitoring

“Lowest redecoration time. Press a button on your mobile phone and change your store…”


High quality lighting makes customers more comfortable, and customers who are more comfortable in an environment tend to stay longer and shop more.

High quality lighting can greatly enhance the desired traffic flow through a retail space, directing customers to intended point of sale areas. Because light conveys emotions, lends spaces atmosphere and makes it easier for people to find their way around.

Quality lighting creates a specific mood for a store that is an integral part of the brand of the retailer, and enhances not only products but the entire experience of the store.

Quality lighting, especially high CRI, enhances the appearance of customers themselves, rendering skin tones and hair in a more flattering light-this is especially important in apparel and jewelry retailing as well as in hospitality, where the positive effects of socializing is enhanced when people look better.
