Solaris9 BK300 vs. AuraDome: Compact Multi-Spectrum Panel or Hands-Free Dome?

Two of Lufalight's most distinctive devices solve very different problems. The Solaris9 BK300 Executive Edition is a compact multi-spectrum unit that packs nine wavelengths into one device, while the AuraDome is a hands-free arch that you sit or lie beneath. Here's how they compare, so you can match the device to the way you actually plan to use it.

What is the core difference between the BK300 and the AuraDome?

The BK300 is built around spectrum range. Its listed output covers red, near-infrared and blue wavelengths from 415nm to 1060nm, plus a UVB channel at 295 and 311nm, all in a compact unit that lists at 32 x 22 x 6.5cm. The AuraDome is built around convenience and coverage: an arch-shaped dome that holds the light for you, so you can sit back without positioning a panel at all.

How do the wavelengths compare?

The BK300 offers nine wavelengths across 415-1060nm plus its UVB channel. The AuraDome runs four wavelengths (415, 590, 630 and 850nm) across 240 LEDs at 40W, with irradiance rated at 50+ mW/cm². If you want the widest spectrum in one device, the BK300 is the broader option. If you want a simpler four-wavelength layout that covers a larger area hands-free, the AuraDome fits better. For more on how different wavelengths behave, see our wavelength-by-wavelength breakdown.

Which one is easier to set up and use?

The AuraDome is the lower-effort option: sit or lie under it and start a session, with a memory function that recalls your last-used mode. The BK300 stands on its own and can be positioned at the distance your manual recommends, which gives you more control over how you aim it but asks a little more of you each session.

What should you know about the BK300's UVB channel?

UVB is a different category from red and near-infrared light, and it deserves extra care. Follow the exposure distance and timing guidance in the manual exactly, use the supplied eye protection, and talk to a doctor first if you have a history of skin conditions, take photosensitizing medication, or are unsure whether UV exposure is appropriate for you. This article does not claim that any device treats, cures or prevents a condition; for how the UVB channel fits into a Canadian winter routine, read our Vitamin D in a Canadian winter guide.

How do warranty and certifications compare?

The Solaris9 BK300 carries a 3-Year Warranty and the AuraDome carries a 1-Year Warranty. The BK300 is an FDA-registered general wellness device; Lufalight devices are manufactured under MDSAP and ISO 13485 quality systems, with Health Canada MDL listing applicable where required for Canadian sales. Our guide to MDSAP and ISO 13485 explains what those certifications do and don't mean. Neither device is a medical device or intended to diagnose, treat, cure, or prevent any disease.

Quick decision checklist

• Want the broadest spectrum in one compact unit → Solaris9 BK300.
• Want a hands-free, sit-back session → AuraDome.
• Prefer a longer warranty window → Solaris9 BK300 (3 years vs. 1 year).
• Want a simple four-wavelength layout over a larger area → AuraDome.
• Not comfortable with UV exposure of any kind → AuraDome, or ask support before choosing.

Frequently asked questions

Can I use the BK300 without the UVB channel?
The wavelengths are listed separately on the product page; check the manual for how to select modes before your first session.

Which one is better for a small apartment?
Both are manageable. The BK300 is the more compact of the two as listed, while the AuraDome needs enough room to sit or lie beneath the arch. For a different size comparison, see our AuraDome vs. LUFAMAX1800 guide.

Safety note: Follow included eye-protection guidance, avoid use during pregnancy or while on photosensitizing medication without consulting a doctor, and stop use and see a healthcare provider if you notice any adverse skin reaction. Individual results vary and are not guaranteed.
