The Brightest Handheld in One Test, With a Cooldown

The Go 2.0 is Joovv's fanless battery handheld, 12 dual-chip LEDs at 660 and 850 nm for one spot at a time, at $549 without its $150 charging dock. Light Therapy Insiders, which earns commission from six competing brands and holds no Joovv code, read 37.1 mW/cm2 at peak at 6 inches on a spectrometer, the highest of the seven handhelds in its 2021 test; a peak is not an average, so output is not scored. Intertek lists the Go 2.0 as ETL classified to the medical electrical safety standard; there is no 510(k), and Joovv's "Class II Medical Device" badge describes the exempt ILY product code it is listed under. Each 10-minute session is followed by a 10-minute cooldown, modes change only through the app, and the same tester timed the battery at about 75 minutes against Joovv's 2 hours. It carries a 1-year warranty, and an opened return within 30 days costs a $50 restocking fee; owners on Reddit report a Bluetooth link that would not connect and a return Joovv refused.

The Joovv Go 2.0 is Joovv's battery handheld: 5.75 x 3.75 x 1.47 in and about 1.32 lb, with 12 dual-chip LEDs at 660 and 850 nm, a silicone grip handle and no fan. Joovv states up to 5 W of light and more than 100 mW/cm2, recommends 10-minute sessions at 6 to 12 in, and follows each session with a 10-minute cooldown. The battery runs up to 2 hours and recharges in about 5.5 hours from a 9 V adaptor. The $549 price includes a travel case and eyewear; the charging dock is $150 more, and changing light modes needs the Joovv app.

Social Scores

Reddit Score3.0

Four owner posts on r/redlighttherapy name the Go 2.0, and none is positive about the device. In September 2024 one owner said she was disappointed with its features and usability and that Joovv did not publish her critical review on joovv.com, and in November 2024 another said the Bluetooth would not connect, Joovv refused the return and a card chargeback recovered the money. In February 2025 an owner of a $500 Joovv handheld said its battery no longer held a charge after about a year, and in January 2024 a new owner asked how to switch the unit off properly.

Google Score6.0

Two written reviews test the Go 2.0. Light Therapy Insiders, which earns commission from six of the seven brands in its handheld test and holds no Joovv code, measured 37.1 mW/cm2 at peak at 6 inches on a spectrometer, the highest of the seven (tested 2021, updated March 2024), and praised the design, grip handle and app modes but ranked it fourth of seven on price. Wareable (May 2026), which earns affiliate commission and runs paid placements for other light-therapy brands on the same page, found it premium-feeling, easy to control through the app and suited to travel, with price the main drawback.

YouTube Score6.0

Four creator videos name the Go 2.0, all from spring 2021, and all four carry a paid tie. Alex Fergus, who uses affiliate codes for competing brands including Mito, measured a 37.1 mW/cm2 peak at 6 inches on a spectrometer in his seven-device handheld showdown (May 2021, 38,700 views), the highest of the group, and timed the battery at about 1 hour 15 minutes, but ranked it fourth on price and faulted the app-only settings, the slow power button and a misleading battery indicator. Barefoot Strength (12,500 views) and High Intensity Health (11,700 views) both received units from Joovv and carry Joovv discount codes; they praised the build, travel case, silent fanless running and the Recovery+ and ambient modes, and Barefoot Strength objected to the proprietary charger and the 10-minute cooldown.

Brand-level

Joovv, Inc. of Reno, Nevada sells its devices direct from joovv.com, and its warranty covers only devices bought there. No US retailer or Amazon US listing carries a Joovv device, so the Amazon and retailer pools are empty at every level. Its Trustpilot profile reads 1.4 from 76 reviews, 86 percent one-star against 5 percent five-star, on a profile Joovv has not claimed, has never invited reviews to and does not answer; the recurring complaints there are email-only support, refused returns and owner-paid shipping on warranty repairs. The BBB rates Joovv, Inc. B+ without accreditation, with 14 complaints closed in three years, and no Joovv device has been recalled.
