Two mock-up office rooms, one with a spectrally tuneable LED lighting system and the other with a fluorescent lamp (FL) lighting system were built for user acceptance studies for office lighting. One room was illuminated with six LED luminaires and the other with six FL luminaires. Each LED luminaire has 480 LEDs (20 different LED types and 24 of each type). Each FL luminaire has eight fluorescent lamps, four with a correlated colour temperature of 4000 K and four of 6500 K. User acceptance…

A Randomized Controlled Trail for Comparing LED Color Temperature and Color Rendering Attributes in Different Illuminance Environments for Human-Centric Office Lighting

The findings are that LEDs with lower CRI values at warm color temperatures and LEDs with higher CRIvalues at cool temperatures provide the right level of color attributes for office lighting.

A Pilot Study Assessing Short-Term Chromatic Adaptation Preferences for Correlated Colour Temperature in India

This small-scale pilot study investigates peoples’ shortterm chromatic adaptation preferences for correlated colour temperature (CCT) within the cultural context of India. White tone CCT preferences

The effectiveness of light-emitting diode lighting for providing circadian stimulus in office spaces while minimizing energy use

The most impactful strategy involved supplementing common overhead lighting with a desktop luminaire delivering light directly to the simulated office occupants’ eyes, which provided greater circadian stimulus and used less energy than overhead luminaires that were capable of delivering the criterion circadian stimulus of 0.3.

Gender Difference in Colour Preference of Lighting: A Pilot Study

If gender difference exists when the observers judge objects with different colours under different E-CCT conditions, there is significant difference between males and females for the 200 lx and 600 lx conditions, especially for the cases with higher CCTs.


Working time, working style, color rendering index and energy benefits are discussed regarding two workspaces, offices and factories, comparatively, comparatively to contribute to literature in terms of indicating key design considerations in two distinctive work spaces.

User preferences for LED lighting in terms of light spectrum

A study was carried out in light booths to investigate user preference for different light spectra and it seemed that light sources with a higher CQS Gamut Area Scale and CZS Colour Preference Scale values were preferred by the observers as far as LED spectra were concerned.

A study of user preferences for fluorescent lamp colours for daytime and night-time lighting

A field study has been made in eight offices in a new municipal building to determine the fluorescent lamp colours preferred by the staff for supplementing daylight and providing the night-time

Subjective preferences and colour quality metrics of LED light sources

To understand people's judgement of the naturalness of object colours and preference for the lit environment, lighting booth experiments were conducted. Seven different LED spectral power

Effect of correlated colour temperature on the perception of interiors and colour discrimination performance

A feature of many national lighting standards is the recommendation that lamps with high correlated colour temperatures should not be used at low illuminances. The technical justification for this

Optimization of LED‐based light blendings for object presentation

Light-emitting diode (LED)-based lighting systems seem to have considerable potential for use in shops and display units, where they may well outperform existing lighting systems.

Color rendering properties of LED light sources

A laboratory human factors experiment was conducted to understand the color rendering properties of various LED-based reading lights. Human subjects rated their preference for a given scene
