The short answer: the Joovv Solo 3.0 is a well-built, app-connected red and near-infrared panel that costs $1,699 on Joovv’s own site (29 Sept 2026, shown as on sale). An independent spectrometer review measured 59.2 mW/cm2 average output, lower than the Mito Red MitoPRO 1500+ and PlatinumLED BioMax 900 in the same reviewer’s measurements, and rated it poor value. You are paying for design, app and modularity, not extra light. Whether any panel helps depends on the outcome: see what the evidence says.
What Joovv states
From Joovv’s product page, read 29 Sept 2026: a 2-year warranty; devices tested and certified by Intertek to recognised medical electrical equipment safety standards including IEC 60601; and the wording that it is a Class II medical device intended to provide topical heating to raise tissue temperature for temporary relief of minor muscle pain, joint pain, minor arthritis pain and muscle spasms, temporary increase in local blood circulation and temporary muscle relaxation, and not intended to diagnose, cure or prevent specific diseases or conditions. The page text we read did not show an irradiance figure. Joovv’s blog says it provides irradiance under a technical section and criticises rivals for measuring with solar meters. We did not verify the technical-section figures.
What an independent reviewer measured
The only spectrometer measurement we found is by Alex Fergus of Light Therapy Insiders, from a review written around 2021 (the panel launched in late 2020) and updated on 7 April 2024, using a Hopoo HSP-350F spectrometer and a Cornet EMF meter. The reviewer is not neutral across brands: the site earns affiliate commission on purchases of some other panels (its Mito and PlatinumLED reviews say so), though for Joovv it states it has no discount code because Joovv runs an exclusive affiliate programme.
Panel size and features from the same review: 150 LEDs (76 red, 74 near-infrared), about 9 by 30 inches, 14 pounds, a timer from 1 to 20 minutes on the panel and up to 90 minutes through the app, four intensity levels in ambient mode, and a 10 Hz pulsing mode that is near-infrared only. The reviewer’s verdict was “Bad Value” despite good build and design. One reviewer, one unit, an older measurement: treat it as indicative.
Against the alternatives
The three-way comparison puts the same reviewer’s numbers side by side: on price listed per average mW/cm2, Joovv came out at about $22.7, Mito about $15.3 and PlatinumLED about $14.4, with the caveats set out there (different sizes and dates, old prices). Joovv’s advantages are non-optical: the vertical stand and handles, the app, stackable modules and the safety certification it cites.
Who it suits
- Consider the Joovv if you want app control, ambient mode and a modular system, and treat output as secondary.
- Look elsewhere if you want the most measured output per dollar; see the Mito Red review and the panel roundup.
- Ask first whether a panel is right for your goal at all: the evidence page grades outcomes, and for sleep timing see the circadian light protocol.

Method note
Researched from Joovv’s product and blog pages and a named third-party spectrometer review (29 Sept 2026). We did not test the product or take any measurement. Prices change; re-check before buying. General information, not medical advice: ask a doctor before using light devices if you have a skin condition, eye condition or take photosensitising medicines.
