Buyers lose weeks when they treat every PDF as proof of brightness or compliance. This guide separates report types and shows how to read irradiance claims without comparing incompatible numbers.
Three report types buyers confuse
| Report type | Example (MMZ01) | What it proves | What it does not prove |
|---|---|---|---|
| IP67 test | BCTC2407052260S | Ingress protection of the mask enclosure per IP67 test | Medical clearance or treatment outcome |
| UN38.3 battery | TSZ25LW001C67-01 (18650, 3.7V/2600mAh/9.62Wh) | Lithium cell transport safety (Tiansu lab, 2025-12-23) | Whole-device electrical safety alone |
| GB 4706.15 safety | CTB240507005Q (2024-05-10) | Household appliance electrical safety for MMZ01 | Optical irradiance or photobiology |
Irradiance: method first, number second
Market listings often cite 30–50 mW/cm² without stating distance, bare LED vs worn mask, or averaging method. That makes cross-supplier comparison meaningless.
| How suppliers often measure | What the number reflects | Comparable to worn use? | Buyer note |
|---|---|---|---|
| Sensor on LED through silicone (single point or average) | Local output at the bead | Partial — still not skin plane | Ask which mode & intensity level |
| Bare LED (no silicone) | Highest headline number | No — not how the mask is worn | Common source of inflated mW/cm² |
| Single bead × total bead count | Theoretical sum | No | Red flag if no test report |
| ~1.5 cm from face (skin plane) | Lower, more realistic dose at skin | Closer to use — rarely published | Radiant does not use this for public labels |
| Unstated method | Unknown | Unknown | Do not compare until method is disclosed |
MMZ01 — mode-specific internal data (Radiant)
Radiant documents through-silicone measurements by therapy mode and intensity level. The public headline 22 mW/cm² refers to Red+NIR, intensity level 3 under that method — not every mode or level.
| MMZ01 mode | Intensity 1 | Intensity 2 | Intensity 3 |
|---|---|---|---|
| Red + NIR (850 + 630 nm) | 12 mW/cm² | 18 mW/cm² | 22 mW/cm² |
| Blue (415 nm) | 14 mW/cm² | 21 mW/cm² | 29 mW/cm² |
| Yellow (590 nm) | 6 mW/cm² | 9 mW/cm² | 10 mW/cm² |
General wellness context only — not a medical treatment claim. Literature on LED devices often discusses roughly 10–100 mW/cm² depending on application and measurement; always ask for the supplier’s stated method before you benchmark.
IEC 62471 (photobiology)
Where a supplier makes strong optical-output claims, ask whether an IEC 62471 assessment exists for your exact SKU and LED layout. If it is not provided, treat photobiology as an open due-diligence item — not as proof by silence.

FAQ
What UN38.3 report should I collect for an MMZ01 kit?
Request UN38.3 for the lithium cell used in the controller (18650, 3.7V/2600mAh/9.62Wh). Radiant’s transport file includes report TSZ25LW001C67-01 issued by Shenzhen Tiansu Calibration and Testing Co., Ltd. (dated 2025-12-23), plus summary, MSDS, and sea/air transport paperwork where applicable.
Does a GB 4706 test report prove irradiance?
No. Report CTB240507005Q is a GB 4706.1 / 4706.15 electrical safety test for MMZ01 (2024-05-10). It does not state optical output (mW/cm²). Ask separately for irradiance methodology and, where applicable, photobiology (IEC 62471) tied to your SKU.
How should I read Radiant’s 22 mW/cm² headline?
Treat it as MMZ01 Red+NIR at intensity level 3 under Radiant’s documented through-silicone bead method (internal Dec 2024 dataset). Irradiance changes by mode, intensity level, and measurement method — compare suppliers only when the same method is disclosed.
