In a sauna you want to feel the glow, not see the bulb. That is why most of what works in here mounts out of sight: behind a backrest, under a bench, or recessed low into the ceiling.
It also has to survive the worst place in the house for a light. The room runs near 200°F with the humidity swinging every time water hits the stones, and ordinary LED tape gives up fast in that. The PROSAUNAS white strip kit is built for exactly that corner, fully sealed to IP67 and rated to 200°F, running on low voltage with the driver kept outside the hot room. It comes as one zone or three, and it dims.
If you would rather run the light off the heater you are already buying, the universal flexible strip package works with any HUUM, Harvia, IKI or Saunum heater and arrives with everything needed to mount it under a bench or behind a backrest.
For light you are meant to look at, the HUUM OVO is a sculpted wood cover in black or natural that throws its glow onto the wall instead of into your eyes. The indoor-outdoor sconce set is the one for a changing room or the wall outside the door.
Pull the low-voltage run while the foil and cladding are still open. Retrofitting a light into a finished room means taking boards back off. Call or text (844) 565-1113 with your heater model and we will tell you which kit runs off it.
