The Key Difference: Indoor vs Outdoor
The fundamental choice between Luminar and Equinox comes down to where you want your sauna. The Luminar is engineered for permanent outdoor installation with weather-resistant carbonized cedar and aerospace aluminum. The Equinox is designed for indoor use with beautiful eucalyptus construction that complements your home's interior.
Heater Technology
Both lines use the same medical-grade full-spectrum infrared technology. The difference is quantity: the Luminar 5-Person packs 15 heaters for its larger cabin, while the Equinox 3-Person uses 7 heaters. Both deliver near, mid, and far infrared wavelengths with low-EMF certification. In practice, both heat evenly and effectively for their respective sizes.
Construction and Materials
The Luminar uses Grade-A carbonized cedar with aerospace aluminum framing - designed to withstand rain, snow, UV exposure, and temperature extremes. The Equinox uses eco-certified kiln-dried eucalyptus, a dense hardwood with a contemporary aesthetic. Both are premium materials, just optimized for different environments.
Installation and Electrical
The Luminar requires 240V hardwired installation ($500-$1,500 for an electrician). The Equinox can run on standard 120V, though 240V is optional for faster heat-up. If installation simplicity matters, the Equinox has a clear advantage.
Our Recommendation
Choose the Luminar if: You have outdoor space, want the ultimate sauna experience, and don't mind the 240V installation requirement. The larger capacity and higher max temperature make it ideal for families.
Choose the Equinox if: You want indoor convenience, prefer a sleek design that fits your home, and want the option of simple 120V plug-in power. It's the better choice for year-round use regardless of weather.
Frequently Asked Questions
Can I use the Luminar indoors?
No, the Luminar is designed exclusively for outdoor use. Its large size, weight (1,270 lbs), and 240V requirement make it impractical indoors. Choose the Equinox for indoor use.
Can I use the Equinox outdoors?
No, the Equinox is designed for indoor use only. The eucalyptus construction is not weather-treated. For outdoor use, the Luminar line is specifically engineered with carbonized cedar and aerospace aluminum.
Which has better heater technology?
Both use the same full-spectrum infrared technology with low-EMF certified heaters. The Luminar simply has more heaters (15 vs 7) due to its larger size, but the quality and type of infrared delivered is identical.
