The Signature II is Sunlighten's more affordable line featuring far-infrared-only heat (not the 3-in-1 near/mid/far blend). Still uses their clinically-tested Solocarbon heaters, which emit 99% efficient far-infrared heat for detoxification and cardiovascular benefits.
The 2-person Signature II offers solid build quality with basswood construction, digital controls, and tempered glass door.
While it doesn't include the smart programming or near/mid-infrared of the mPulse line, it delivers excellent far-infrared therapy at a more accessible price. Heats up in 15-20 minutes to temperatures between 100-130°F.
Perfect for anyone who primarily wants detox and cardiovascular benefits and doesn't need the additional near/mid-infrared for skin and pain relief. Still a premium sauna, just more focused.

"The Signature II does exactly what we need—great detox sessions without breaking the bank. We didn't need all the bells and whistles of the mPulse. Heats up quickly and the Solocarbon heaters are noticeably effective."
