How to build stylish sauna lighting, which also makes the space more functional?

Lighting brings atmosphere and safety to the sauna. Nowadays there are numerous options for lighting the sauna, so it can be difficult to make decisions. Are the LED lights or fiber optic lights best for your sauna? Would the stove lights and illuminated meters be nice accessories, or should I stay in simple lighting?

Lighting is always a matter of practicality and safety. Here are tips how to build a stylish lighting to your sauna without forgetting practicality.

The key question of sauna lighting

Should the sauna be atmospheric or more brightly lit?

You can and should trust your own taste in the matter of the amount of light and also in other issues related to sauna lighting. Other ideas are worth listening to, but finally everyone is the best expert in their own sauna.

However, there are some rules of thumb for the amount of light. Lighting is an important mood creator, but a certain amount of light is necessary from a safety standpoint.

The need for light can also vary surprisingly much between the different bathers, and it may not only be the matter of taste. For example, a 60-year-old person requires about twice the amount of light to see as well as a 20-year-old person.

The easiest solution is to install a dimmer in the lights. In this case, each user of the sauna can adjust the brightness exactly as desired.

Lighting makes the final touch to the sauna interior

The placement of luminaires is one of the most important decisions affecting the atmosphere of the sauna. The rule of thumb is to illuminate the sauna and not the bathers.

Light can be brought into space in many ways. It is worth considering whether you feel more comfortable with the light from the ceiling or in the benches, or perhaps a combination of them. Are the spot lights or indirect even light best for the sauna? The lighting can be finalized with a stove light, for example.

There may be areas in the sauna that are worth lighting for the sake of safety and comfort. These include stairs, a stool, a sauna water bowl and possible meters. One of the very latest trends is the glass-made optical bars that can be mounted in the ceiling and on the stove wall. Illuminated with optic glass fibres, the bar can withstand heat really well.

The final lighting of the space is also influenced by factors other than the number of lights. For example, if the same lighting is built on a white or black sauna, the white feels too bright and black too dim. The colors of the sauna also affect the lighting choices.

LED lights or fiber optic lights for a sauna?

In lighting design you must also take into account safety regulations. They limit lighting techniques and lighting placement.

Nowadays, the most popular technologies are LED lighting and fiber optic lighting, as well as their various combinations. You must be careful in the selections, so that the product meets the requirements of the installation site.

Fiber optic lighting can be designed quite freely, as there is no electricity in the fibers themselves.

Instead, the placement of LED lights is restrictive. There are also places where LEDs should not be installed in any case. These include the space around the heater. The distance of the LEDs from the heater must be at least 50 centimeters in each direction. The heater lighting can therefore only be carried out with fiber optics.
