The deep, working heat.
The longest wavelength of the three. Penetrates deepest and drives the bulk of the sweat response - the part most people feel as the "real" sauna heat.
Amplify pairs full-spectrum infrared - far, mid, and near, blended in one cabin - with LED chromotherapy and built-in Bluetooth audio. Three cabin sizes on the floor in Hamilton.

Every Amplify uses the same full-spectrum heater array, the same eight-colour LED chromotherapy, and the same 7-year warranty. Pick the footprint that fits your room.
Compact two-seater built for couples, daily solo sessions, or a quiet stretch at the end of a long day. Fits in a master bath, a den, a converted closet.

The middle child everyone gravitates to. Wider bench, room to recline, fits comfortably in a basement gym or finished bonus room.

The largest Amplify. Built for family sessions, training partners, and back-to-back recovery. The footprint your home wellness room is waiting for.

Where the Signature line gives you far infrared alone, Amplify layers far, mid, and near together. You feel deep heat, recovery warmth, and surface penetration in the same 30 minutes - no mode switching, no menu to learn.
The longest wavelength of the three. Penetrates deepest and drives the bulk of the sweat response - the part most people feel as the "real" sauna heat.
Sits between far and near. Mid is associated with tissue and circulation - a useful band on the days you trained hard or sat at a desk too long.
The shortest of the three infrared wavelengths. Sits closest to visible red light. Used in skin and cellular research circles for its surface-level absorption.
Wavelength descriptions reflect published research and what owners report. An infrared sauna is a wellness device, not a medical device. Talk to your doctor before using one if you are pregnant or managing a condition.

Chromotherapy is built into every Amplify - not a bolt-on, not an upgrade. Cycle the cabin through eight colours from the touch panel. Set it once for the mood you want and pair it with the cabin's built-in Bluetooth speakers.
Amplify is for the owner who wants the full-spectrum heat without an app, a tablet, or a learning curve. The premium build of the mPulse line. The everyday rhythm of the Signature line. None of the menu screens.
Far, mid, and near infrared - delivered together so a single session covers depth, recovery, and surface warmth without you switching modes.
Set time and temperature on the in-cabin touch panel. Step in. Sweat. That is the entire learning curve. Bluetooth audio is standard, not an add-on.
A cabin you can put in a bedroom without it announcing itself. Hardware that hides. Hinges that close clean. The kind of build that earns the 7-year warranty.
Bench depth, back rest geometry, and floor heater placement are tuned for sessions you actually repeat - not a hotel showpiece you use twice.
Three cabin lines. Same 7-year warranty. The right choice depends on how much technology you want between you and a sweat.

Signature is the entry Sunlighten cabin - far infrared only, smaller sizing. Amplify steps up to full-spectrum heat (far, mid, and near infrared blended together), pairs that with LED chromotherapy and built-in Bluetooth, and gives you three cabin sizes to choose from. Same 7-year warranty across the line.
Amplify II runs on a dedicated 120V 20-amp circuit - a standard household line, once it is on its own breaker. Amplify III can run 120V or 240V depending on the configuration. Amplify IV needs a dedicated 240V circuit. We confirm the exact requirement for your room and panel before delivery.
Plan 30 to 45 minutes inside the cabin once it is warm. Amplify pre-heats in roughly 15 minutes from cold, so budget a 45 to 60 minute window from when you turn it on to when you step out.
Yes. All three Amplify cabins are on the floor at our Hamilton showroom - 1171 Upper James St Unit 9A. Book a visit and a member of our team will warm one up so you can sit inside it.
