Criterion	Sunlighten mPulse Aspire	Clearlight Sanctuary 2
US price	Price on requestChecked Oct 20, 2026 · Price details in the review	Price on requestChecked Oct 13, 2026 · Price details in the review
Three-year ownership estimate	$319.30 Incomplete known subtotal. Electricity assumption: $0.18/kWh. Not included: purchase price, installation, other annual costs.	Not enough data Incomplete known subtotal. Not included: purchase price, installation, other annual costs, energy use.
Choose if	One person with a dedicated 120 V, 20 A circuit who wants red light and several infrared wavelengths in one cabin.	Two adults with a 20 A outlet and about 60 × 56 in of floor space who'd rather have long warranty coverage than a published price.
Main trade-off	Sunlighten publishes no price, and you can't return the cabin once the boxes are opened.	The price is quote-only, labor coverage ends after 7 years indoors, and a return costs 25% plus freight and the original shipping.
Key specifications	Heaters: 5 far-infrared, 4 mid-infrared and 3 near-infrared and red LED panels. Sunlighten says its PulseIQ platform controls the four wavelengths separately. 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. It says that's lower than dedicated LED devices. No independent measurement is given Electrical: 120 V, 18 A, 2,160 W per the assembly guide.

Exact variant	1-person installed infrared cabin with red light, eucalyptus or basswood	2-person full-spectrum infrared cabin, mahogany (basswood also offered), 120V / 20A plug-in
Dimensions	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.	Outside: 51 3/4 W × 47 3/4 D × 77 H in. Inside: 46.5 W × 44.25 D × 72.5 H in. The owner's manual asks for at least 4 in of clearance on all sides for air circulation. The product page recommends the same 4 in if you build it into an enclosed space.
Installation	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.	It plugs straight into a 120 V, 20 A wall receptacle with a NEMA 5-20P plug. It's rated at 18.83 A, close to the circuit's 20 A rating. Clearlight doesn't say you need a dedicated circuit or an electrician. The manual calls for a properly grounded 3-wire socket and advises against extension cords. It strongly recommends a GFCI in potentially wet locations, and asks for a dry, level surface with at least 4 in of clearance. The sauna ships by liftgate freight, with a scheduled delivery appointment. Clearlight's general assembly page says two people usually assemble it in about 1 to 1.5 hours, using a screwdriver and the included Allen wrench. Installation service is available in some areas, at no stated price. Outdoors, Clearlight requires its optional canvas cover, with the sauna on a deck or concrete pavers.
Materials	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.	Mahogany or basswood, which Clearlight describes as genuine, furniture-grade natural wood. It says the heaters combine ceramic and carbon.
Warranty	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.	Clearlight says parts and shipping are covered for life, with 7 years of labor for indoor use. Its lifetime residential warranty covers the entire sauna for as long as you own it: the wood cabin, True Wave heaters, controls and electrical components, audio and chromotherapy lighting. The 7 years comes from the "Sauna Works Limited Lifetime Warranty" table in the owner's manual, for indoor residential use in the USA and Canada only. Outdoor residential use is covered only if you bought Clearlight's water-resistant cover with the sauna and kept it on, and the manual limits cabin and labor coverage there to 5 years. Commercial use also carries a 5-year warranty. The warranty page says registration is automatic when the sauna ships, while the manual says you must register within 30 days of purchase. The manual also says the warranty can't be transferred without Clearlight's written consent.
Returns	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.	Returns are accepted within 30 business days of receipt, and you need a Return Merchandise Authorization. Clearlight calls it a "30 Day Risk-Free Return Policy", but returns aren't free. The sauna has to be in new or like-new condition, in undamaged original packaging with all manuals. The refund is the purchase price minus any original shipping charges and a 25% restocking charge. If the sauna shipped under a free or discounted shipping promotion, the actual original freight cost is deducted. You pay return shipping. Custom, private-label and non-standard models are non-refundable. You must open the boxes and inspect them for concealed damage within 5 business days of delivery.
