Per-heater wattage isn't stated Red and near-infrared light: Sunlighten says the LED panels peak at 650 nm (red) and 880 nm (near-infrared) and deliver 1 to 3 mW/cm² to the skin.

Exact variant	3-person Full-Spectrum Infrared Sauna	1-person installed infrared cabin with red light, eucalyptus or basswood
Dimensions	HigherDOSE lists the 3-person exterior as 61 W × 41 D × 76.5 H in. The interior is 57 in (the dimension is unlabeled) by 36.25 in deep and 70 in high, and the cabin weighs about 580 lb. Confirm the exact unit and clearances before measuring your room.	Outside: 43.6 W × 41.6 D × 79 H in, including 2 in feet. Inside: 37.8 W × 35.6 D × 71.5 H in. The bench is 37.8 in wide and 21.7 in deep, 20.2 in off the floor. It weighs 463 lb in eucalyptus and 432 lb in basswood. Sunlighten recommends 4 in to the walls and 6 in above the cabin. Sunlighten gives no minimum doorway width and asks you to measure doorways and hallways before you buy.
Installation	It needs a dedicated 240 V, 15 A circuit. HigherDOSE rates it at 2,930 W with a NEMA 6-15P plug, so you'll need a matching NEMA 6-15 outlet. An upgraded cord is available on request, ships separately and is yours to fit. Installation isn't included. The carrier leaves the sauna on a pallet, as far as it can get along the road or driveway. Delivery to a room of your choice costs extra, by quote from HigherDOSE's sauna sales team. No assembly time or manual is published, and the page has only a "How to build" heading.	It needs a dedicated 120 V, 20 A circuit and outlet with a NEMA 5-20 plug. Sunlighten's assembly guide rates it at 120 V, 18 A and 2,160 W. The 10 ft cord exits at the back left of the floor and must plug straight into the wall. The assembly guide says to add a GFCI or dual-function breaker only if your local code requires one. The spec sheet says dual-band Wi-Fi (2.4 and 5 GHz) is required, while the product page says recommended. Freight goes to a garage or a flat, paved driveway, where the carrier leaves it on a pallet and can't carry it up steps. You need two people to unpack and assemble it, which Sunlighten's FAQ puts at 1 to 2 hours, and professional installation isn't required.
Materials	HigherDOSE describes the exterior as black mahogany and the interior as basswood. These are the maker's descriptions, not independently verified species or emissions results. The finish and cabin-specific VOC testing are unknown. The resource page's fabric test covers the sauna blanket, not this cabin.	Sunlighten says each sauna is built from sustainably sourced eucalyptus with natural variation in tone and grain. Its spec sheet also lists basswood. It lists kiln-dried wood, thick insulation, a glass front door and side glass, and CELLIANT fabric covers over the heaters on the interior walls. Its safety page calls the glue non-toxic, citing testing by Franklin International.
Warranty	The product page promises a limited 5-year residential warranty and a 1-year commercial warranty. HigherDOSE's warranty page has no sauna section, only one-year terms for eight other products. It doesn't publish what the 5 years covers, so heaters, controls, labor, parts shipping and transfer are all unclear. Ask for the written sauna warranty before you order.	Sunlighten's warranty page gives the cabinetry and heaters 7 years for home use, and one set of terms covers its mPulse, Signature and Amplify cabins. Coverage is for replacement parts only, with no labor or technician costs. You pay freight on parts shipped for service, and the page excludes costs or freight for parts shipped more than 90 days after delivery. Controls (tablet, control pad and power box) get 3 years, the glass door and audio get 1 year. Chromotherapy and the Blaupunkt sound system carry a separate 1-year manufacturer's warranty. Commercial use gets 5 years on the cabinetry and heaters and 1 year on controls, glass and audio. It covers only the original buyer and ends if you transfer ownership, and the sauna must be bought and put into use within a year of its manufacture date. It's void if the sauna is altered, misused or exposed to water. It's also void on a power strip, extension cord, converter or non-dedicated circuit. The same goes for a spot within 5 ft of a shower, tub or cold plunge, or a repair attempted without consulting Sunlighten. Sunlighten says its saunas aren't designed for outdoor use, and outdoors the separately sold cover must stay on at all times, even during sessions. The page doesn't say whether the red and near-infrared LED panels count as heaters.
Returns	HigherDOSE's return policy gives Full Spectrum Saunas 30 days from delivery, but only if unopened and in the original packaging. Every approved return carries a 30% restocking fee, about $2,700 at the 3-person price. You also pay all return shipping. The 120-day money-back guarantee in the site banner doesn't cover saunas. The policy was last updated May 8, 2025.	You have 30 days from delivery to return it, but only while it's unopened in its original packaging. Opened saunas can't be returned or exchanged. Fees can include a 3% administrative fee and a $499 restocking fee for each mPulse sauna. They can also include storage fees, return shipping to the warehouse and shipping back to you on an exchange. To cancel before it ships, email your sales representative, and the same fees may apply. To return it, email your sales representative for an authorization, or Sunlighten's logistics team if you have none. Sunlighten then schedules the pickup and refunds your original payment method after it inspects and restocks the sauna. Sunlighten reserves the right to refuse a return, exchange or cancellation.
Unresolved questions	Installation clearances Heater count and placement Wood finish and cabin-specific VOC testing What the 5-year warranty covers, including labor and parts shipping, and whether it transfers Whether the cabin carries an ETL, UL or CSA listing, and its file number Measured EMF levels and how they were tested Average power draw and preheat time, and so the running cost Assembly time and what an installation manual would require, such as GFCI protection	The price, and which models the Sale ends 10/31/26 footnote covers A ship date or lead time for the Aspire, since the shipping page says the estimated ship date varies by model Whether any EMF measurement covers the Aspire, since the Vitatech report tested other models and the safety page's 0.5 mG figure gives no model or distance The ETL file number and which models it covers A top cabin temperature Average power draw once the cabin is up to temperature The minimum doorway width its panels and cartons need Whether the 7-year heater warranty covers the red and near-infrared LED panels Whether your local code requires GFCI protection, and what an electrician would charge The tablet's screen size, and whether there's an automatic shut-off Whether the sauna works without Wi-Fi, since the spec sheet lists dual-band Wi-Fi as required and Sunlighten doesn't say
