We’re surrounded by light, but are we really using it in the best way?
Light pollution doesn’t just happen outdoors; indoors too, at home, in the office, or in a store, poor lighting can impact well-being, distort the atmosphere, and even drive up your energy bill.
The good news? You don’t need major changes to make a difference. With small actions and more mindful choices, you can create a space that’s more balanced, comfortable, and energy-efficient.
So, what exactly is light pollution?
When we hear this concept, it’s easy to picture a night sky veiled by a haze of artificial light, disturbing our natural rhythms and even affecting animals that rely on darkness to survive.
But the truth is, the problem starts much closer to home, within our own spaces. Excessive, poorly directed, or improperly toned lighting can:
▪️ Cause visual fatigue
▪️ Disrupt the circadian rhythm (especially at night)
▪️ Increase energy consumption unnecessarily
▪️ Make the environment feel less welcoming
Discover how to avoid this with 5 simple, yet rarely discussed tips.
1. Choose lighting with directional cut-offs
Not all light serves the same purpose. Indoors, it’s essential to light with intention.
Fixtures with directional cut-offs and anti-glare diffusers provide soft, effective lighting, free from harsh reflections or unwanted shadows.
Pro tip: focus light only where it’s needed, like the kitchen counter, your workspace, or bedside table. This way, you enhance visual comfort and avoid unnecessary energy use.
2. Choose warm, balanced lighting
Cool lights (like bluish white) might look modern, but they quickly become harsh – especially at the end of the day. The right color temperature makes all the difference!
▪️At home, we recommend warm light between 2700K and 3000K: it’s cozier, more relaxing, and sleep-friendly — perfect for living rooms and bedrooms.
▪️For workspaces, go for neutral light (around 4000K): it’s more energizing and focused without being uncomfortable, ideal for staying productive without straining your eyes.
❌ Avoid cool light in rest areas.
✅ Use each type of lighting where it makes the most sense. Your well-being will thank you!
3. Control the lighting schedule
Does your home or balcony really need to stay fully lit until you go to bed? And what about the office? Do the lights need to be on when no one’s there? Probably not.
Installing timers, motion sensors, or smart home systems is a simple (and smart) way to stay comfortable without wasting energy.
Controlling your lighting means controlling the atmosphere—and the bill.
4. Rethink decorative lighting
Lighting up a historic facade? Perfect. But does that intense spotlight on the garden at 3 AM really make sense?
Decorative lighting can bring life to a space, but it should be used in moderation. Avoid light spots that overwhelm or disrupt the harmony of the environment. Opt for discreet solutions like LED strips, table lamps, or recessed lights that create softer, more immersive atmospheres.
A good lighting design enhances, it doesn’t saturate. And don’t forget: less is more.
5. Plan (or ask for help from someone who knows!)
Lighting a space is much more than choosing beautiful or strikingly designed fixtures. A good lighting study ensures the right light in the right places, without unwanted shadows, glare, or overlooked areas.
