Making Every Lumen Work.
Supermarket lighting is often reduced to one question:
How bright should the store be?
But the best-lit stores are rarely the brightest.
They are the most deliberate.
A good supermarket lighting strategy should answer five questions:
1. Are we lighting the shelves — or the floor?
Customers look at products, not the floor. Vertical illumination matters.
2. Does the shape of the light match the shelf?
Long aisles need controlled, elongated distributions — not overlapping circles of light.
3. Is the light uniform, or simply bright?
800 lux under a luminaire and 300 lux between luminaires may look impressive on paper, but still feel uncomfortable in reality.
4. Does the light make the product look right?
Fresh food needs accurate colour rendering. CRI, CCT, R9 and colour consistency all matter.
5. What happens when the store changes?
Shelves move. Categories change. Promotions rotate. A good lighting system should adapt with them.
This changes the way we should think about efficiency.
It is not just about lm/W.
It is about how much of that light actually reaches the merchandise.
Less wasted light.
Better product visibility.
Better visual comfort.
More flexibility.
The goal isn't to add more light.
It's to make every lumen work.
What do you think matters most in supermarket lighting today — energy efficiency, product presentation, or visual comfort?
