That subsidiary's own store also sells the Amplify line.

Where it sells

Sunlighten, Inc. sells saunas from a one-person dome to four-person full spectrum cabins on its own US store, shop-us.sunlighten.com.
Its mPulse cabins are sold through sauna consultants without a priced cart.
No Sunlighten store or listing was found on Amazon US in November 2026.

Description

The Sunlighten Solo Dome Chromo is a one-person personal sauna: two rigid bamboo carbon dome sections that lock together with pins and slide over a user lying down. Five SoloCarbon far infrared heaters draw 1,260 W, and a control box sets the upper and lower domes separately, with a timer up to 60 minutes.

The manual gives a range of 113 to 149°F, and the store page says up to 150°F. It plugs into a standard 120 V outlet with a NEMA 5-15 plug, needs no dedicated circuit, measures 69 by 28 by 18 inches, and weighs 46 lb. Chromotherapy lights with a remote, a curtain and a pillow come with it.

The Solo System Chromo adds the heated SoloPad for $2,099.00 on the same store, and the pad alone is $849.00. Sunlighten's own 2020 report from Vitatech Electromagnetics gives 0.57 mG RMS for the Solo at the user's position.
