Choose if	Two or three people who want red light built into their sauna and can add a dedicated 240 V, 20 A circuit.	Two adults with about 57 × 54 in of floor space and a lightly loaded 15 A outlet who want a near-infrared panel included at a published price.
Main trade-off	You pay $1,600 extra for red light with no published wavelength or dose, and opened saunas can't be returned.	The 1,780 W draw nearly fills a 15 A circuit, the panel has no published wavelength or output, and beyond the heater core, harness and wiring the warranty runs 10 years, with warranty labor at your expense.
Key specifications	Heaters: 7 far-infrared, 5 near-infrared red-light and 3 full-spectrum heaters. The red light's wavelength and output aren't stated Electrical: 240 V, 3,465 W and 14.44 A, on a dedicated 20 A circuit with a NEMA 6-20R outlet Inside and bench: 56.8 W × 39.9 D × 70.3 H in inside. The bench is 56.6 W × 20.2 D in and 19.5 in off the floor Top temperature: Up to 170°F, which Sunlighten qualifies with "in ideal conditions" Heat-up: Sunlighten suggests preheating for 45 to 60 minutes. It says the cabin warms about one degree per minute, depending on room temperature Weight and delivery: 710 lb in two to three boxes on a pallet, left in your garage or driveway. Two people assemble it in about 2 to 3 hours Extras: Chromotherapy lighting and a sound system Options: The 2-person Amplify RED II costs $900 less and the 4-person Amplify RED IV $1,700 more. Without red light, the same-size Amplify III Eucalyptus is $1,600 less	Heaters: Eight heaters in all. Tecoloy Dual-Wave on the walls and bench (mid- and far-infrared, per the product page). True Infra far-infrared on the floor and lower back. The info sheet instead says the Tecoloy heaters provide near-, mid- and far-infrared. Count per location and heater wattage aren't stated Near-infrared panel: 96-diode LED panel, included as standard. The product page calls it near-infrared. The info sheet describes it as a customizable 9-color near-infrared panel. Wavelength, irradiance and wattage aren't stated Electrical: 120 V, 1,780 W, 15 A (the info sheet lists 1,810 W). NEMA 5-15P plug for a standard 120 V, 15 A outlet Temperature and timer: Maximum 170°F (75°C). Session timer runs 5 to 60 minutes in 5-minute steps. Overheat error at 180°F (82°C). The product page FAQ says most users find 120–140°F comfortable and suggests a 20–30 minute preheat. The manual says to allow about 15 to 20 minutes to warm up Capacity and interior: 2 people (the info sheet says 1 to 2). Interior is 45 W × 39.5 D × 71.5 H in Controls and extras: Digital touch-panel controller for temperature, session time and lighting. Bluetooth audio.

Exact variant	3-person infrared cabin with integrated red-light configuration	2-person indoor infrared cabin, Indonesian mahogany, Tecoloy dual-wave mid/far-infrared heaters plus a standard 96-diode near-infrared LED panel, 120V/15A plug-in
Dimensions	Outside: 62.3 W × 45.9 D × 77.7 H in, including 2 in feet. Inside: 56.8 W × 39.9 D × 70.3 H in. The door opening is 28 in. The bench is 56.6 in wide and 20.2 in deep, 19.5 in off the floor. The eucalyptus model weighs 710 lb. Sunlighten says it fits under a standard 8 ft ceiling and its panels fit through a standard 30 in doorway. The product page gives no clearance to leave around the cabin.	Outside: 47.25 W × 43.5 D × 77 H in. Inside: 45 W × 39.5 D × 71.5 H in. The manual asks for at least 5 in of clearance from walls on all sides, so plan on about 57.25 × 53.5 in of floor space. Health Mate doesn't state the weight or bench size.
Installation	It needs a dedicated 240 V, 20 A circuit and a NEMA 6-20R outlet for its 6-20P plug. Sunlighten tells you to book your electrician early so the outlet is ready on build day. Its FAQ says a power strip or converter voids the warranty. The warranty page also rules out extension cords and non-dedicated circuits. It requires at least 5 ft between the sauna and any source of water or vapor. The product page doesn't mention GFCI protection or clearance around the cabin. Freight arrives in two to three large boxes on a pallet, left in your garage or on a flat, paved driveway spot. The carrier calls first to schedule. The panels lock together with Magne-Seal corners, without screws or nails. Sunlighten says two people take about 2 to 3 hours. Its guides page has manuals and assembly guides for the standard Amplify II, III and IV, but none listed under Amplify RED.	It plugs into a standard 120 V, 15 A outlet with a NEMA 5-15P plug, and the product page says "no electrician needed." The catch is the load. The 1,780 W rating works out to about 14.8 A at 120 V, which leaves the circuit little room for anything else. The manual says to confirm the breaker matches the sauna's rating and not to share the circuit with too many appliances. It also calls for a properly grounded three-wire outlet and strongly recommends a GFCI in potentially wet locations. The cabin must be freestanding (not built into a structure) on a level, dry surface. It ships crated on a pallet by freight, with lift-gate service and a scheduled appointment, typically in 7 to 12 business days. Standard curbside delivery is free. The product page lists inside delivery and white-glove delivery as quoted separately, and says extra fees may apply if the carrier needs special access or handling. According to the manual, the magnetic wall panels need no tools. The shipping page says two people can assemble it in 30 minutes or less. For outdoor use, the manual says it needs a cover and a spot under an awning or overhang.
Materials	Eucalyptus tongue-and-groove boards on solid wood framing, which Sunlighten calls sustainably sourced and non-toxic. Basswood and Obsidian finishes were marked not available for this model. One line on the page says its saunas are made of basswood, which conflicts with the eucalyptus selection. Sunlighten says the glue on its boards was third-party tested by Franklin International.	100% Indonesian mahogany. Health Mate notes that grain, tone and finish vary. The info sheet describes a wood interior and exterior with limited see-through glass. The handle is stainless steel.
Warranty	Sunlighten's warranty page groups Amplify with its other cabin saunas. For home use, the cabinet and heaters get 7 years, the controls 3 years, and the glass door and audio 1 year. Cabinetry includes benches, floor grates and heater cover frames. Controls include the control pad, in-sauna tablet and power box. Commercial use gets 5 years on the cabinet and heaters and 1 year on everything else. The cabin terms don't single out the red-light heaters. The general terms cover replacement parts only. Labor and technician costs aren't covered. You pay all freight, including on parts shipped for service. Coverage is for the original buyer only and ends if you sell the sauna. It's void on a power strip, extension cord, converter or non-dedicated circuit, or within 5 ft of water. Outdoors, the plastic sheet of the sauna cover (sold separately) must stay on at all times, even during sessions. The sauna must be bought and put into use within a year of its manufacture date. The page shows no version or effective date.	The product page markets a "Limited Lifetime Warranty," but the same page's FAQ says only that Health Mate saunas come with a 10-year warranty on wood. The owner's manual is more specific. Its warranty section is headed "10-Year Limited Warranty" and applies to saunas bought after 2024. It gives lifetime coverage to the heater core, harness and wiring. Coverage is 10 years on the cabin and frame, paneling, flooring, door and glass, handles, electronic controls and wiring, interior and exterior lighting, interior audio, and labor of factory-installed components. A second, shorter column of 1 to 5 years applies to what the manual defines as commercial use. Despite that labor row, the same terms say labor to replace cabin, frame, hardware and component parts isn't covered. All warranty labor must be done by the customer or a contractor, at the customer's expense. You pay shipping on parts in both directions, and removal and reinstallation costs are excluded. A claim requires timely registration. The warranty can't be assigned or transferred unless Health Mate approves. Upgrades, options, parts and accessories follow their own manufacturer's warranty, and the near-infrared LED panel isn't named. The coverage table has no outdoor column, so it doesn't address outdoor placement, which the manual allows with a cover. Health Mate's warranty page words the lifetime offer as applying to new full-size saunas purchased in 2025. Its warranty sheet is titled "Limited Warranty."
Returns	Non-custom saunas can be returned within 30 days of delivery, but only unopened in the original packaging. Opened saunas can't be returned. Fees can include a 3% administrative fee, a $499 restocking fee per Amplify sauna, storage fees and return shipping. Cancelling before it ships can cost the 3% fee, plus storage fees if it has to be rerouted.	Health Mate accepts returns within 30 business days of receipt, with a return authorization (RMA) number. The sauna must be in new or like-new condition, in undamaged original packaging with all manuals. The catch is cost. The refund is reduced by a 20% restocking charge (about $1,060 at list price) and any original shipping charges. You also pay return shipping. Custom, private-label and non-standard models are non-refundable. An order canceled before shipment is fully refunded. After shipment, a cancellation is handled as a return. The returns policy gives 5 business days to inspect for concealed damage. But the shipping page says damage must be noted on the delivery receipt and reported within 1 day (24 hours) of delivery.
Unresolved questions	The red-light heaters' wavelength and irradiance, and whether they run at the same time as the far-infrared heaters Average power use during a session, and so the yearly running cost Whether the circuit needs GFCI protection, and how much clearance to leave around the cabin What the linked Amplify RED III spec sheet adds, since it couldn't be opened on Oct 13, 2026 Whether an ETL listing covers this exact model, and its file number What the Vitatech EMF test measured, at what distance, and whether it included the red-light heaters Whether it's in stock, since the product page and Sunlighten's store listing disagreed The lifespan and replacement price of the full-spectrum and red-light heaters Whether the $8,599 sale price lasts past the October 14 event	Cabin and crate weight, bench dimensions, and heater count and wattage by location Near-infrared panel wavelength, irradiance and wattage How a "9-color" panel relates to near-infrared output, since near-infrared itself isn't visible Whether the near-infrared panel runs separately from the heaters Whether the lifetime offer, worded for 2025 purchases on the warranty page, applies to 2026 orders Whether the LED panel is covered by the warranty How the 10-year labor row fits the manual's statement that warranty labor is at the customer's expense Which wattage figure (1,780 W or 1,810 W) is correct Prices of inside delivery, white-glove delivery and the promo savings behind the offer form Listing number and model scope behind the Intertek ETL mark Whether any app or smart control exists. The comparison page tags Enrich 2 as Smart without defining it and lists App Control only for Inspire models. The same page's $5,300 Classic Enrich Series card says "Doesn't have smart features"
