Pick your panel, set your distance and duration, and get a J/cm² dose with biphasic-window guidance — cited to peer-reviewed PBM literature by PMID. Track cumulative dose per body region with the Arndt-Schulz biphasic guardrail. Brand-aware preset library covers Mito Red Light, Joovv, and GembaRed, with per-model peak irradiance sourced from LightLab International Allentown (ISO/IEC 17025-accredited) or each vendor's published spec page. Not a medical device. Lumen does not diagnose, treat, or cure any condition. It is a calculator, a citation reference, and a session log. You bring the goals; Lumen does the dose math against the literature. Why named-source citations matter: photobiomodulation literature is rich but inconsistently summarized. Lumen surfaces "Cited to Huang/Hamblin 2011 PMID 22461763" on every dose band, "Cited to Freitas/Hamblin 2016 PMID 28070154" on the mechanism explainer, and per-panel LightLab or vendor URLs on every irradiance value. Every default traces to a source you can verify yourself. Features • J/cm² dose calculator with inverse-square distance scaling from each vendor's reference distance to your actual treatment distance • Brand-aware panel preset library — Mito Red Light (MitoPRO 300X, 1500X, 300+ v2, 1500+ v2, 750X stub with lab-audit-pending badge), Joovv (Solo, Quad, Elite 3.0), GembaRed (Groove, Reboot) • Per-panel wavelength composition disclosure (660 nm red, 810 / 850 nm near infrared, etc.) • Biphasic-window dose bands — below therapeutic, low therapeutic window (5–10 J/cm² per PMC11991943 2025 review), extended therapeutic, caution, overshoot risk — cited to Huang, Sharma, Carroll, Hamblin 2011 PMID 22461763 • Multi-target session log: face, shoulders, joints, back, full body, or any custom target you add • Per-target cumulative dose chart with weekly biphasic band overlay • Custom panel entry for any panel not in the preset library • Reference cards: Arndt-Schulz biphasic curve explainer, cytochrome c oxidase mechanism explainer (PMID 28070154) • Citations & Sources tab: every Tier 1 PMID, every Tier 2 vendor URL, with last-verified dates • Universal app for iPhone and iPad Free download with the panel preset library (read-only browse), single-session J/cm² calculator on one panel, the biphasic-curve reference card, the mechanism explainer, and the full Citations & Sources screen. $6.99 one-time unlocks Lumen Pro permanently: multi-panel session log, cumulative-dose tracking with biphasic-window guardrails, distance-aware calc across saved panels, per-target trend charts, custom panel entry, and unlimited targets and sessions. 24-hour trial starts when you first tap a Pro feature.
