Notes on these figures

No irradiance or power density published on UK, EU or US brand pages or Amazon UK. Figures seen on a Dutch retailer (Kruidvat) relate to the different 'Artemis Blush' model and are not used.

Light-output figures come from the manufacturer. Independent checks are rare, even in published studies, so treat them as claims. Why

Using it

Treatment

Session length: 10, 20 or 30 (selectable); 10 recommended (US page)
Details
UK page offers 10/20/30 min with no recommended length. US spec table: '10/20/30 min (10 min recommended)'. Amazon UK: '10 to 30 minutes each time'.
How often: 3 to 4 times per week Retailer-stated
Details
Amazon UK listing text (brand-supplied listing, sold by Amazon). Not stated on renpho.uk. Amazon also advises a first-use skin test and starting at lowest intensity for 5 minutes.
Modes: 3 light modes (Red + NIR 630/850 nm; Blue 415 nm, described on UK page as Blue + NIR 415/850 nm; Red + Blue + NIR); 5 intensity levels; 10/20/30 min timer Conflicting information
Sources differ: UK page description: 'Blue + Near-Infrared (415nm + 850nm)'. Same page's mode panel is headed 'Blue Light' (though text mentions NIR); Amazon UK: 'blue light(415nm)' only.

Details
Whether NIR runs in the blue mode is inconsistent — see conflicts.
Auto shut-off: Timer-based (10/20/30 min)
Details
Pages describe a timer; explicit auto-off wording not seen. Confirm in manual.

Design and power

Power: Rechargeable handheld controller connected to the mask by cable; input 5 V, 1 A; USB charge cable included
Sources differ: Amazon UK title: 'Cordless, Rechargeable'. Brand UK product data: 'a corded remote'; images show controller on a cable.

Details
UK product data: 'a corded remote to adjust light, intensity, and treatment time'; product images show the controller on a cable. Amazon UK title says 'Cordless, Rechargeable' — i.e. not mains-tethered during use, but the controller is wired to the mask. Input rating from US spec table. Not the same as the cordless 'Artemis II Aër'.
Battery: 2000 mAh (7.4 Wh), 3.7 V; operating time >45 min; not user-replaceable
Details
UK page image: '2000mAh Long-Lasting Battery'. Voltage, Wh and operating time from US spec table (same E100B model). Amazon UK: 1 lithium-ion battery included.
Charge time: 2.5 hours
Details
US page spec table only; not on UK page.
Use while charging: — Not disclosed
Details
Would be in the manual, which was not obtained.
Eye protection: Removable eye cups
Details
Amazon UK lists '1 pair of eye protection goggles'. US page: 'Always wear the provided eye cups and avoid direct light exposure.'
Weight: 185 g Retailer-stated
Details
Amazon UK 'Item weight 185 Grams'; same listing gives 'Package Weight 0.92 Kilograms' and repeats 185 g against package dimensions, so unreliable. Not stated by brand.
App needed: No
Details
Controlled from the handheld controller; no app mentioned for this model.
Subscription: No
Details
No app or paid features mentioned.
Replaceable battery: No
Details
US page: 'Do not attempt to open, modify, or replace the battery yourself'.

Values are as stated by RENPHO unless marked otherwise.

Allergy to light therapy, silicone or plastics

Regulatory status

UK: UKCA Not disclosed
Details
No UKCA or CE wording found on the UK product page or Amazon UK listing. Manual (where markings usually appear) not obtained.
EU: Declaration of Conformity Not disclosed
Details
Renpho EU 'Compliance Data' page publishes DoCs for scales, massagers etc.; none listed for E100B / Artemis.
US: FDA 510(k) clearance Not disclosed
Details
openFDA 510(k) search: no records for applicants 'Renpho', 'Joicom' or 'Rocdan'; 'Artemis' device-name hits are unrelated products. Renpho's site advertises 'FDA clearance' only for the separate Artemis II Aër mask, not this model. OEM not named, so clearance under another applicant cannot be fully ruled out. US status only — not a UK approval.
UK: Intended purpose: Cosmetic wording ('enhance radiance, smooth signs of aging…'); some medical-sounding claims (acne bacteria, inflammation) Manufacturer-stated
Details
No medical-device classification stated. MHRA registration not checked.

A conformity mark or US FDA clearance doesn't prove a device works. "Not published" doesn't mean unsafe. If you have a medical condition, are pregnant or take light-sensitising medicines, ask your GP or pharmacist first.
