The scientists compared an Artificial Skylight (AS) with natural daylight and LED lighting to see how well they performed. They asked people to work in a room with different lighting setups and furniture, collecting over 360 surveys to understand the effects. AS and daylight are similar in providing a pleasant environment and affecting people's body clocks positively, but they can sometimes cause glare issues. The study found that the workstation with even lighting was the most comfortable, and AS, even though it uses more light than LEDs, offers better light quality. They suggest more research is needed to improve AS design and make buildings more efficient.
