How does proper in-store lighting affect sales


"How important is lighting to increasing sales in retail? This question has a very simple answer: "The better the lighting, the better the visibility. That's why dark corners in sales areas can lead to "dead zones," which negatively affects the financial efficiency of the sales area as a whole. To make the most of the retail space, you need to pay attention to lighting and act consistently."
Front porch

Evaluate fairly how well your porch and entrance are lit. Lack of brightness can lead to a 15-20% reduction in visitors. This is because passersby don't pay proper attention to the entrance, and therefore there is no spontaneous desire to enter the store. If the steps and part of the façade around the entrance are well lit, however, it is possible to move into the sales area.
Entrance Group

Have you ever noticed that when you enter a sales floor during the day, it is often very dark for the first 3-4 meters after the entryway, and then your eyes begin to get used to the light and you begin to distinguish the merchandise? This can cause discomfort and cause shoppers to move at a high rate of speed at the entrance, slowing down only when they begin to see the merchandise. This blinding effect can lead to a loss of valuable entrance area and discourage shoppers. So what to do in this situation?

The fact is that the level of illumination on the street in cloudy weather is about 2000 lux, while in the trading halls of even the most modern stores, this figure is about 1000 lux. In order not to lose customers in the entrance area, you need to provide a bright light, about 2000 lux, immediately after the entrance and gradually reduce it to an average light level of 1000 lux.
Store lighting standards recommend a light level of 300-400 lux. On an overcast day, there are about 2000 lux outside, which indicates that the light level in the store is much lower.

The generally accepted norm is a grocery store lighting level of 1,000-1,200 lux, not including special shop lighting. Lighting quality is also important and includes brightness, color rendering, and color temperature of light. The best choice for general store lighting would be neutral white lamps with a color temperature of 4000K. Many stores save on lighting by choosing lamps with a 640K or 33K color temperature, which corresponds to a color rendering of only 65%.

This lighting makes food colors look gray, blue and green rather than bright and appetizing, as bright colors suffer. For products to look good, fluorescent lights must be at least 840, which is 85% color rendering. Proper design of general store lighting will help avoid frequent mistakes when choosing bulbs.

The first mistake is inadequate and uneven lighting.

The next mistake is the use of indiscriminate raster lights installed in the ceiling.

This system is already outdated and now most modern retail facilities use a more advanced cross-shaped trunking system, which allows you to achieve high uniformity of lighting.

Of course the cross-shaped system is quite expensive, so the system is still a pipe dream for many supermarkets. In such cases, stores often try to install their own lighting "lines" on an existing ceiling.

One of the most common mistakes in such do-it-yourself installations is installing lighting lines in aisles, exclusively along aisles and along shelves. The basic rule when installing a linear system is that it must be installed perpendicular to the aisles!

For example, if in your salesroom the rows of racks are arranged perpendicular to the incoming flow, and on the left of them are parallel, then the line system should be installed vice versa: on the right parallel to the entrance, and on the left perpendicular. Many people wonder what the connections between the lines look like in this case.

When organizing proper lighting in a store, it is important to keep in mind that light falling from windows can create an unwanted counter effect and drown out all other light sources in the room. This is especially noticeable on walls that appear dark and insufficiently illuminated in front of the windows.

If you plan to place racks in such an area, goods will not be visible enough, even with the lights on. Considering that about 80% of shoppers walk along the perimeter of the sales floor, and only 40% go into the center, windows take up the most valuable space in the store. So while it may seem wrong to board up the windows, it should be done.

In addition, it is worth considering that daylight has a color temperature of 6500K, corresponding to a blue glow. This can negatively affect the visual perception of departments such as confectionery or butchery, which will look gray or blue, which does not create a desire to buy products.
Bread and Pastry Department

The bakery and pastry department requires special lighting to bring out the natural colors of the products. Lamps with a color rendering index of 85% and a light color temperature of 3000K are recommended for general building lighting. The ceiling of the section is usually lowered for aesthetic and functional purposes, but it is possible to use rotary lights aimed at the products to highlight them as much as possible.
Gastronomic row

For the gastronomic row, including cheeses, salads, fish and sausages, additional lighting is recommended to emphasize the different shades of products. For example, a concentrated bell light with a metal halide lamp will highlight the natural colors of fish.
Cash registers

Cash registers require sufficiently bright lighting (1,500 to 2,500 lux) for convenient calculations. It is recommended to use a luxmeter to measure the level of illumination. To get the best results, it is recommended to ask professionals to create a mini lighting project.
