ProSun Onyx 12 Review (2026): The Level 4 Commercial Tanning Bed for Salons & Gyms

What Is the ProSun Onyx 12 Minute Level 4 Commercial Tanning Bed?

The ProSun Onyx 12 Minute Level 4 Commercial Tanning Bed is a salon-grade UV tanning bed built for businesses — tanning salons, gyms, day spas, and fitness centers adding tanning as a revenue amenity. It's a Level 4 bed, meaning it uses higher-output lamps than entry-level Level 1–3 salon beds to deliver a 12-minute maximum session, and at 83" x 35.5" it's sized to fit into a standard tanning room without the footprint (or price tag) of ProSun's larger units. 

One clarification worth making up front: the standard Onyx is all about tanning and is a full UV tanning bed. It doesn't include red light tanning lamps like you will find featured in Hybrid models. If you're comparing hybrid UV/red light options for a commercial space, this isn't that; if you want a dedicated, high-output UV bed focused to maximize tanning performance for paying customers, this is the unit built for exactly that.

Why Salon and Gym Owners Choose the Onyx 12

The case for the Onyx 12 in a commercial setting comes down to three things: footprint, control, and cost of entry. At 83" x 35.5", it fits into an 8'x8' room, which is small enough for most existing tanning rooms or a converted office. The T-Max system is built in from the factory, so you can daisy chain it to other units or attach your remote T-Max Timer or Control Manager at the front desk to control the sessions remotely while the bed itself still lets the customer override the delay time from inside — standard for a salon workflow where staff manage multiple rooms at once. And at $6,900, it's positioned below ProSun's more expensive units, which makes it a realistic first commercial bed for a new salon or an added amenity for a gym or spa.

The bed itself carries 12 x 160W and 5 x 140W lamps in the canopy plus 14 x 100W lamps in the bench, along with a 400W facial lamp for more even facial coverage — a step up in output from lighter-duty beds, which is what allows the 12-minute session ceiling.

Electrical & Installation: What a Commercial Buyer Needs to Know

Unlike ProSun's 120V home units, the Onyx 12 Minute Level 4 requires a dedicated 220V circuit on a NEMA 6-20R outlet with a 25-amp breaker, and ProSun specifies that incoming voltage needs to stay between 218 and 230 volts. If a building's electrical service can't hold that range consistently, a 0.50 kVA single-phase buck booster should be installed at the fuse box to protect the warranty. A 110V outlet is also needed when operating with a T-max system. This is a commercial electrical install and should be done by a licensed electrician — budget for that as part of the total cost of bringing the bed online, not just the equipment price.

Who the Onyx 12 Is Built For

This bed is aimed squarely at businesses: a start-up tanning salon adding its first bed, an existing salon replacing an aging Level 3-4 unit, or a gym, fitness center, or spa adding tanning as a member amenity without dedicating a large room to it. It's not built or priced for home use but many tanning aficionados who want the best use do use the bed after setting up the necessary 220v dedicated circuit with a 25 Amp Breaker and NEMA 6-20R wall receptacle.

ProSun Onyx 12 FAQ

Does the ProSun Onyx 12 include red light therapy?
No. The Onyx 12 Minute is a UV-only commercial tanning bed. ProSun's hybrid UV/red light options including the Onyx 12 Hybrid can be viewed here and full red light units with no UV tanning can be viewed here. 

What electrical setup does the Onyx 12 need?
A dedicated 220V circuit with a NEMA 6-20R outlet and a 25-amp breaker, installed by a licensed electrician. Incoming voltage needs to stay in the 218–230V range, or a buck booster may be required.

What's the maximum session time on the Onyx 12?
12 minutes.

What room size does the Onyx 12 need?
ProSun recommends an 8 ft x 8 ft room at minimum, given the bed's 83" x 35.5" footprint.

Is the Onyx 12 suitable for home use?
It's built and priced as a commercial bed for salons, gyms, and spas. Home buyers looking for a bed that runs on standard 120v household power should look at ProSun's 120V home lineup instead, such as the Jade 32 120V Hybrid Tanning Bed or the Sundream 120V Hybrid Canopy. If you install a 220v circuit with 218-230v, a 30 Amp dedicated breaker and a NEMA 6-20R Wall receptacle your home can be set up correctly to support the Onyx 12 Minute bed and achieve the pinnacle in residential tanning luxury. 

Who shouldn't use the Onyx 12?
Per FDA sunlamp product requirements, it's contraindicated for anyone under 18 or with skin lesions or open wounds present, and it should not be used by anyone who has had skin cancer or has a family history of skin cancer.
