HARVIA Lighting

Sauna lighting from a light strip concealed under the bench

Harvia lighting is a range of lighting solutions from the Finnish sauna technology manufacturer Harvia, designed for both sauna interiors and exteriors. It includes light strips, spotlights and fibre-optic sets that are installed into the ceiling, benches or around the cabin door. The products are designed to operate at the high temperature and humidity of a Finnish sauna, an environment different from standard interior lighting. Harvia also offers solutions compatible with its own control units, where lighting is operated together with heating and ventilation from a single control panel or app. The brand is an established sauna technology manufacturer with a long history in Finland.


Advantages of Harvia lighting

  • Designed for the sauna environment: Components withstand high temperature and humidity without loss of function, unlike standard interior lighting.
  • Integration with the control system: Lighting can be controlled together with heating and ventilation from a single interface.
  • Multiple installation formats: Light strips, spotlights and fibre optics allow the solution to be adapted to different interior types.
  • An established industry standard: Components and servicing are widely available through an established Finnish sauna technology manufacturer.

Types of sauna lighting

Lighting in a sauna is handled differently from an ordinary interior, because the light fitting has to withstand high temperature and moisture and at the same time must not dazzle. In practice three approaches are used, and they can be combined.

Why ordinary LED strips are not enough for a sauna

The temperature at the ceiling of a Finnish sauna is well above what ordinary interior LED strips and their power supplies are rated for. The critical point is usually not the diode itself, but the electronics and the adhesive. Solutions intended for saunas either use components rated for these temperatures, or work with optical fibres, where the light source sits outside the cabin. In both cases the power supply is fitted outside the hot space.

Frequently Asked Questions

Basic lighting, yes; full integration into a single control interface, however, works most reliably with a Harvia control unit.

It offers both types: standard LED fittings and fibre-optic sets that carry light from a single source to multiple points in the interior.

Yes, the components are certified for operation under Finnish sauna conditions, including repeated temperature cycles.

With selected product ranges, yes, combined with RGB or dimmable modules controlled via a panel or app.

It requires professional installation, due to the low-voltage wiring and its placement in a high-humidity, high-temperature environment.

Yes, the manufacturer also offers watertight variants designed specifically for outdoor cabins and mobile saunas.
