Joovv vs Mito Red vs PlatinumLED: Claimed vs Measured Output

The short answer: in the only independent spectrometer measurements we found that cover all three brands, the PlatinumLED BioMax 900 measured highest (90.3 mW/cm2 average at 6 inches), the Mito Red MitoPRO 1500+ next (76.5) and the Joovv Solo 3.0 lowest (59.2), with Joovv also priced highest. All three measured below the brands’ own headline claims where a claim exists. Higher measured output does not by itself mean better results: see the evidence by outcome. All measurements come from one reviewer, at different dates, on different sized panels.

Three kinds of number, kept apart

Brand claims, a brand-commissioned lab report and an independent reviewer’s spectrometer are not the same thing, so the table separates them.

Attribute	Joovv Solo 3.0	Mito Red MitoPRO 1500 line	PlatinumLED BioMax 900
Brand claim	Joovv’s site lists irradiance under a technical section; we could not read a figure on the product page on 29 Sept 2026	About 170 mW/cm2, measured with a solar meter (as described by the reviewer); brand’s lab fluence 3.4 J/cm2 per minute (about 57 mW/cm2)	Charts on its site; PlatinumLED states it uses a handheld solar meter centre-point test and a separate third-party spectrometer test (numbers not readable in text)
Brand-commissioned lab	Joovv states Intertek certification to IEC 60601 medical electrical safety standards (safety, not irradiance)	LightLab International, ISO/IEC 17025 lab, 6 inches, Sept 2025: MitoPRO 1500X 72.5 mW/cm2 peak, 149.4 W total radiant power	None read
Independent spectrometer (Light Therapy Insiders)	Peak 72.4; average over 9 spots 59.2 mW/cm2 (Hopoo spectrometer); red only 45.2, near-infrared only 66.3	1500+: peak 87, average 76.5 mW/cm2 at 6 inches; 136 W total	Peak 113, average 90.3 mW/cm2 at 6 inches (75 at 12 inches); 186 W total
Measured wavelengths	660.7 nm and 853.6 nm (claimed 660 and 850)	Peaks at 630, 660, 833-834 and 855 nm	Seven wavelengths listed, 480 to 1,060 nm
Price the reviewer listed	$1,345, later $1,445 (Apr 2024)	$1,169 (Aug 2024)	$1,299, later about $1,339 (Jul 2024)
Price on brand site, 29 Sept 2026	$1,699 (shown as on sale)	Not the same model: the 1500 line is now sold as MitoPRO X and MitoPRO+ v2 (MitoPRO X from $449 for the smallest size)	Not re-read
Warranty as stated	2 years	2 years (entry series); 60-day money-back	3 years; 60-day return with a 20% restocking fee (reviewer)

Price per unit of measured output (our arithmetic)

Dividing the price the reviewer listed by that reviewer’s average measured irradiance:

Panel	Price listed	Average measured	Price per average mW/cm2
Joovv Solo 3.0	$1,345	59.2	about $22.7
Mito Red MitoPRO 1500+	$1,169	76.5	about $15.3
PlatinumLED BioMax 900	$1,299	90.3	about $14.4

Treat this as a rough guide. The panels are different sizes, the prices are two years old and have moved, and irradiance per area says nothing about coverage; total radiant power is a better size-adjusted figure where a reviewer gave it (Mito 136 W, PlatinumLED 186 W; not stated for the Joovv in the text we read).

What to keep in mind

• One tester. All independent figures above are from Light Therapy Insiders (Alex Fergus). The reviewer is affiliate-tied: the site earns commission on purchases through its links, the Mito review says the reviewer receives a commission on purchases through its links and discount codes, and the PlatinumLED review says the reviewer is affiliated with PlatinumLED. For Joovv the reviewer states there is no affiliate code. We found no second independent measurement of the same units.
• Old units. The Joovv review was written around 2021 (the panel launched in late 2020) and updated in April 2024. Product generations change. The Mito panel measured was the 1500+; the brand’s current lab data is for the 1500X.
• Peak versus average. Peak is the brightest spot. Average across the face is closer to what a body part receives.
• Wavelength counts. More wavelengths on a spec sheet is a marketing point; the trials pooled in one evidence review used wavelengths from about 655 to 905 nm, and no trial shows that extra bands beat two well-chosen ones.
• Safety certification differs. Joovv states Intertek certification to IEC 60601; Mito states FDA Class II registration, ETL/UL listing and IEC 60601 on select devices. Check the current claim for the exact model.

Which one, and when

• Highest measured output for the money in these measurements: the PlatinumLED BioMax 900, then Mito. See our BioMax 300 review (an older, smaller model) and the Mito Red MitoPRO 1500 review. You can find the Mito panels on Amazon.
• App control, ambient mode and modular expansion: the Joovv, see the Joovv Solo 3.0 review. It is the priciest per measured output.
• Checking any panel yourself: use the checklist in the panel roundup.

Method note

Compiled on 29 Sept 2026 from the reviewer’s articles, Mito Red Light’s published testing page, and Joovv’s and PlatinumLED’s own pages. We did not measure or test any panel. Prices are as the reviewer listed them at the time, not current prices, and Joovv’s current site price was read separately. Arithmetic is ours. General information, not medical advice.
