Light, Mood and the 3pm Brain Crash
What Your Lighting Says About Your Workplace (Before You Do)
If your workplace lighting feels like a spreadsheet with a ceiling grid, your team is probably working harder than they need to. Research keeps telling the same story: access to daylight, glare-free ambient light and circadian-aware schemes make people feel more alert, less sleepy and more productive across the workday. Think of it as swapping out that 3pm energy crash for a space that feels quietly keeps the brain switched on, not by being brighter everywhere, but by being smarter about where and how light shows up.
Design-wise, I like to treat a workplace more like a city than a single “on/off” room. Some pockets like to buzz, like the spots where people arrive, bump into each other or grab a quick coffee. Others want to feel like tucked-away side streets where you can hear yourself think. When I’m working with an interior designer or architect on a workplace, we usually start by mapping how the day flows through the plan. Where people arrive, pause, collaborate and where thy need real focus. From there, the lighting can do some quiet but important work: softer, layered lighting in arrival and breakout areas so they feel warm and social, calmer, low-glare lighting over workstations so screens are comfortable, and a bit more control in meeting rooms, focus pods and collab zones, so you can dial the mood up or down depending on what’s happening in the room. The technical bits such as illuminance levels, optics, controls are all handled in the background, but what we want people to really notice is that the light feels appropriate at different times of the day, instead of being one flat setting from 8 till 6.
And the fun bit is that light can be used to give your workplace its own personal brand. Your lobby and open office are already saying something about you and lighting just decides what whispers, mumbles or actually tells the story that you want your clients and future hires to hear. On projects, I love finding those signature moments with the design team. It could be a logo on the wall that feels crisp, a favourite collaboration corner that has that has a quiet glow of its own in the evenings, or meeting rooms where people consistently say, “This feels nice, what’s different in here?”. Done well, lighting becomes a quiet part of your identity and the thing that makes a client remember “the space that felt so considered”, and a candidate think, “Oh, these people really care about how we work here”, all before a conversation.
