Clearlight, Sunlighten and Sun Home compared on current 2-person prices, 120V installation, testing, warranty, returns and the tradeoffs that matter.
Comparison
Quick answer: Sun Home Equinox 2P is our current Best Overall choice among these three premium infrared brands. It combines a public $6,099 price, a dedicated 120V/20A installation path and the most inspectable model-level VOC and EMF evidence. Sunlighten Amplify II is the better value if its current $5,799 price and 170°F stated maximum, five degrees above Equinox in this indoor matchup, matter more. Clearlight Sanctuary 2 is the safer long-term choice if a limited lifetime warranty and nearly three decades of brand history outweigh the higher price.
Best for
US buyers choosing a premium two-person indoor infrared sauna from Clearlight, Sunlighten or Sun Home.
Wrong fit
Buyers who want traditional high-temperature heat, steam and stones, or an outdoor cabin.
Tradeoff
Sun Home wins on inspectable evidence, Sunlighten on current full-spectrum value, and Clearlight on warranty depth and ownership history.
This is a $5,799 to $7,299 decision before delivery, electrical work or accessories. The three cabins look similar on a spec sheet, but the brands ask you to make three different bets.
Our current Best Overall choice among these three is the Sun Home Equinox 2P. It is not the cheapest and it does not have the longest warranty. It wins because Sun Home gives an evidence-first buyer the clearest package before checkout: a public price, exact 120V electrical requirements, a numeric third-party EMF report and a cabin-air VOC report with the lab, method, date and result visible.
That label has limits. Sunlighten currently sells a lower-priced full-spectrum two-person cabin and publishes 170°F versus Equinox's 165°F in this indoor matchup. Clearlight has the strongest published residential warranty and the longest ownership history of the three. If either matters more to you than documentation, choose accordingly.

How we compared them
We checked the manufacturers' current US product, price, electrical, warranty, return and testing pages on August 18, 2026. For the closest fair matchup, we compared two-person indoor full-spectrum cabins:
Sun Home Equinox 2P
Clearlight Sanctuary 2
Sunlighten Amplify II
We weighted five things that change the purchase: delivered product price, electrical setup, heater and temperature claims, inspectable safety/material documentation, and what the written warranty and return terms leave with the owner.
We have not completed a long-term ownership test or a warranty claim with any of these cabins. Manufacturer specifications are labeled as published claims, not as our own test results. Sale prices and policies can change, so the final written order controls.

The detail most comparisons miss
Sun Home Equinox 2P and Sunlighten Amplify II publish the same exterior dimensions, interior dimensions, bench dimensions, 1,880W draw, 15.67A draw and dedicated 120V/20A requirement. Both also describe a magnetic panel assembly system.
That is not proof that they are the same sauna. Their published heater counts, stated temperature, warranty language, controls and evidence packages differ. It does mean the brand story should not decide this purchase by itself. Put the current Equinox and Amplify spec sheets side by side and compare what is actually different.
Why Sun Home is our Best Overall pick
The evidence is inspectable
Sun Home links to a Vitatech magnetic-field report with a 0.5 mG seated-position result and a cabin-air test reporting 27 µg/m³ total VOC using EPA Method TO-15 through an AIHA-LAP-accredited laboratory. It also publishes an adhesive report showing no formaldehyde or BTEX above the report's detection limits.
Those documents do not prove a sauna is risk-free or that every future production unit will produce the same reading. They do let a buyer inspect the sample, method, lab and measurement position instead of accepting a "low EMF" or "non-toxic" badge on faith. That is the strongest reason for the overall verdict.
The buying path is clear
The Equinox 2P is $6,099 with free shipping shown on the current product page. Its 120V, 20A circuit requirement, NEMA 5-20P plug, wattage and clearances are listed before checkout. A buyer can price the cabin and ask an electrician the right question without entering a consultation funnel.
The $300 premium needs to earn its keep
Sunlighten Amplify II is currently $300 less and publishes a 170°F maximum in ideal conditions versus Equinox's 165°F. The Equinox premium is worthwhile only if you value Sun Home's more inspectable testing package and simpler evidence trail. If you do not, Amplify is the value winner.
What Sun Home does not win
Sun Home was founded in 2021, so it cannot offer the ownership history of Clearlight or Sunlighten. Its Equinox warranty is seven years on cabinetry and heaters, three years on controls, and one year on glass and audio. Its published return terms do not allow returns after a sauna has been opened, assembled or used.
Why Clearlight wins warranty and track record
Clearlight's strongest argument is not a heater-count table. It is the limited lifetime residential warranty covering heaters, controls, electrical, wood and included audio, paired with nearly three decades in the infrared category.
The two-person Sanctuary 2 currently lists at $7,299 in basswood and $7,699 in mahogany. It uses a dedicated 120V/20A circuit, so it does not force a 240V upgrade in this comparison. Clearlight also publishes a strong low-EMF and low-ELF position.
The tradeoff is price. You are paying $1,200 more than Equinox and $1,500 more than Amplify at the prices we observed. That can be rational if warranty depth and an older installed base matter more than the newest test-document package. Ask Clearlight for the exact current warranty PDF, freight total and model-level EMF/ELF report with your quote.
Choose Clearlight if: you plan to keep the sauna for many years and want the strongest written warranty promise of these three.
Why Sunlighten wins current full-spectrum value
Sunlighten's Amplify II changed this comparison. Its current official product page lists a two-person full-spectrum cabin at $5,799 with free freight shipping, a dedicated 120V/20A setup and a stated maximum of 170°F in ideal conditions. That is five degrees above Equinox's published 165°F maximum in this specific indoor infrared matchup.
That five-degree edge does not make Sunlighten the higher-heat brand across every sauna format. Sun Home publishes a 0-170°F range for the outdoor infrared Luminar and notes that heat-up time depends on ambient temperature. Its Nova traditional sauna uses a HUUM DROP heater that Sun Home describes as designed to reach 230°F. Those products involve different installation and heat-format decisions, so they are context rather than direct alternatives to Amplify II.
That makes it the cheapest comparable full-spectrum cabin here, not the expensive quote-only option older comparisons describe. Sunlighten still keeps mPulse pricing behind a consultation, but Amplify is now directly purchasable.
The warranty is seven years on cabinetry and heaters, three years on controls, and one year on glass and audio. The written terms say replacement parts are covered, while labor, technician costs and freight after the first 90 days remain with the owner. Opened saunas cannot be returned, and the current return terms list possible administration, restocking and freight charges.
Sunlighten says its cabins use third-party-tested low-EMF and low-VOC technology. The public buying path we reviewed did not make the exact Amplify II test reports as easy to inspect as Sun Home's numeric reports. Ask for those documents before treating the claims as equivalent.
Choose Sunlighten if: you want the current lowest price for a comparable two-person full-spectrum cabin, or you prefer its 170°F stated maximum to Equinox's 165°F in this indoor comparison.
The real cost is not just the sauna
All three comparable cabins use a dedicated 120V/20A circuit. Do not read "120V" as "plug it into any nearby outlet." Have an electrician confirm that the circuit is dedicated, correctly protected and uses the required receptacle before delivery.
Also price these items in writing:
Freight destination and whether delivery stops at the curb, driveway or garage.
The people or service needed to move heavy panels to the final room.
Electrical work, permit requirements and access clearances.
Return freight and restocking charges if the sealed shipment is refused.
Labor, travel and parts shipping after the first 90 days of warranty coverage.
Replacement cost and manual fallback if an app, display or control box fails.
Buy Sun Home Equinox 2P if you want our Best Overall pick and care most about public, numeric evidence before checkout.
Buy Clearlight Sanctuary 2 if the strongest warranty and older track record justify the premium.
Buy Sunlighten Amplify II if you want the lowest current price and a higher stated maximum than Equinox in this indoor full-spectrum matchup.
Stop and reconsider infrared if what you really want is hot air, stones and steam. Read infrared vs traditional sauna before spending $6,000 on the wrong heat style.
Frequently Asked Questions
How does Sun Home compare to Sunlighten and Clearlight? Is it actually as good?
Yes, Sun Home belongs in the same premium infrared shortlist. Equinox matches Sunlighten Amplify II on published footprint and electrical requirements, costs less than Clearlight Sanctuary 2, and offers the most inspectable public test package of the three. The tradeoff is a shorter company history and a seven-year cabin/heater warranty instead of Clearlight's limited lifetime coverage.
Is Sunlighten still worth buying or have there been a lot of problems recently?
Sunlighten is still worth buying when a specific model wins the comparison. Amplify II is currently the lowest-priced comparable full-spectrum two-person cabin here and publishes a 170°F maximum in ideal conditions, five degrees above Equinox in this indoor matchup. Before buying, get the warranty exclusions, return costs, exact test documents and control-replacement path in writing. Owner complaints are useful questions to investigate, but they are not a measured failure rate for every current unit.
