SaunaBox Pulse PRO vs SaunaSpace FireLight (2026): two portable saunas that heat you in completely different ways
By SaunaBox · Published August 10, 2026
Short answer
These are not the same kind of sauna and the specification table will mislead you if you read it as a like-for-like list. The SaunaSpace FireLight is an open near-infrared bulb sauna — four incandescent bulbs at 1,000 W radiating onto you, wrapped in organic cotton canvas. The SaunaBox Pulse PRO is an enclosed insulated tent with ThermoCell panels and an integrated 660–850 nm red light, at $699. SaunaSpace does not publish a US price on its product page. It carries a 5-year warranty; SaunaBox does not match that.
One of these heats you with bulbs pointed at your body in an open frame. The other encloses you in an insulated cabin and heats the space. Both are portable, both fold away, and both are marketed as an infrared session at home — but the mechanism, the published specifications and the price transparency are different enough that picking between them is mostly a question of which approach you want, not which is better value on a row-by-row read.

Where these numbers come from. SaunaBox Pulse PRO figures come from the product page on saunabox.com. SaunaSpace FireLight figures come from sauna.space and a European authorised retailer, retrieved August 10, 2026. SaunaSpace confirms that Faraday and Luminati are previous names for the same product, now sold as the FireLight. Any figure a manufacturer does not publish is marked Not published rather than estimated.

SaunaSpace points light at you. Four 250 W incandescent bulbs sit in a panel and radiate near-infrared onto whichever part of you is facing them. You rotate. The canvas is a light shield and a modesty screen, not insulation. Advocates prefer this because it is close to full-spectrum incandescent light and the session is short and intense.
SaunaBox heats the enclosure. ThermoCell panels line an insulated tent with a MylarMax reflective interior, so the cabin holds heat around your whole body at once. You sit still. It is closer to the experience of a cabin sauna, scaled down to something that folds into a cupboard.
Neither is objectively correct. But they produce different sessions, and someone who wants one is usually not satisfied by the other. Decide the mechanism first, then look at the price.
SaunaSpace does not publish a US price on the FireLight product page. You configure a sauna — Classic or SuperSauna, natural or coloured, with or without SilverLining shielding — and the price appears at the end. A European authorised retailer lists the Classic at £4,995 and the SuperSauna at £6,445, which gives you the order of magnitude even if it is not the US number.
The SaunaBox Pulse PRO is $699. One number, on the page, before you give anyone an email address.
We are not going to pretend a configurator is a scandal — plenty of considered purchases work that way. But when the comparison question is what does this cost , one of these two answers it immediately and the other does not.
Warranty. Five years, published, against a Pulse PRO warranty SaunaBox does not publish on the product page. That is a clear win and it should be weighted properly.
A 100-day trial. On a product where the mechanism is unusual and you genuinely may not like it, a long return window is worth real money.
Material provenance. North American basswood, GOTS-certified organic cotton, stainless steel, organic bamboo. That is a well-documented bill of materials and it is published clearly.
Red light in nanometres. 660 nm and 850 nm, integrated into the tent. SaunaSpace describes red and near-infrared therapy but does not publish the wavelengths. If you are buying for red light specifically, only one of these tells you what you are getting.
PFAS testing and OEKO-TEX certification. The Pulse PRO cover is OEKO-TEX certified and independently tested PFAS-free. Given that both products wrap you in fabric in a hot enclosed space, what the fabric is tested for is a fair question, and only one of the two answers it. Note this claim applies to the Pulse PRO specifically and is not a SaunaBox-wide claim.
No consumables. Bulbs are a wear part. Panels are not. Over a five-year ownership window that is a running cost on one side and not the other, though neither company publishes a bulb replacement interval.
Frequently asked questions
How much does the SaunaSpace FireLight cost?
SaunaSpace does not publish a US price on the FireLight product page; pricing is shown through a configurator after you select a model and options. A European authorised retailer lists the Classic at GBP 4,995 and the SuperSauna at GBP 6,445. The SaunaBox Pulse PRO is $699.
Are the SaunaSpace Faraday and Luminati different products?
No. SaunaSpace confirms that Faraday and Luminati are previous names for the same sauna, now sold as the FireLight, with EMF shielding offered as an option rather than as a separate model.
Do both publish red light wavelengths?
No. The SaunaBox Pulse PRO publishes an integrated 660 nm and 850 nm red light. SaunaSpace describes red and near-infrared therapy for the FireLight but does not publish specific nanometer wavelengths.
Which one has a warranty?
SaunaSpace publishes a 5-year warranty and a 100-day trial period on the FireLight. SaunaBox does not publish a warranty length for the Pulse PRO on its product page. This is the row where SaunaSpace is clearly stronger.
What is the difference between bulb saunas and panel saunas?
A bulb sauna radiates near-infrared from incandescent bulbs directly onto the part of your body facing them, in an open frame. A panel sauna heats an enclosed insulated space around your whole body at once. The sessions feel different and most buyers have a clear preference.
How much do they weigh?
The SaunaSpace FireLight is 44.9 lb in Classic configuration and 51.9 lb as the SuperSauna. The SaunaBox Pulse PRO is 52 lb. They are effectively the same weight.
Is either fabric tested for harmful substances?
The SaunaBox Pulse PRO cover is OEKO-TEX certified and independently tested PFAS-free. SaunaSpace publishes GOTS-certified organic cotton canvas but does not publish PFAS testing. Both publish their material provenance clearly.
Do either of them publish an EMF certification standard?
Neither names a standard. SaunaSpace describes low-EMF bulbs and offers a SilverLining shielding option it says blocks 99.99% of external EMF frequencies, without naming the test standard. SaunaBox describes the Pulse PRO's heating as infrared panel based and does not publish an EMF certification for it.
Can I use HSA or FSA funds on either?
A sauna can qualify as a medical expense under 26 U.S. Code section 213(d)(1)(A) when a licensed provider issues a Letter of Medical Necessity. SaunaBox supports this through TrueMed at checkout. Eligibility depends on your provider and plan.
The Pulse PRO is 52 lb, folds flat, wraps you in an OEKO-TEX certified and PFAS-tested cover, and publishes an integrated 660 nm and 850 nm red light. The price is on the page.
