Full-spectrum on our desk

Means Finnmark-style kit marketing: listings describe short-wave heaters plus carbon long-wave panels. We do not lab-certify wavelengths. We send you to Topture when a stock kit fits.

Far-infrared on our desk

SaunaCloud’s public education treats far-IR as the heater job. Optional red/NIR is a light add-on (Atlas One makes it standard).

Who should skip

Skip spectrum arguments if the room doesn’t fit a kit and power/moisture aren’t fixed.
Skip medical shopping here — we don’t diagnose or promise outcomes.
Skip outdoor cabin as an IR-spectrum pick — different product.

Bottom line

Full-spectrum here ≈ Finnmark kit path. Far-IR custom ≈ SaunaCloud quote path. Measure room and circuit before the slogan.
