Our Test Data Is Public. Check It Before You Buy

LEDs don't emit one exact wavelength — every diode peaks within a small range. So here's what our devices actually deliver: red peaking between 630–670nm, near-infrared between 810–850nm — the two windows the research points to — with each device's exact peaks on its product page.

You don't have to take our word for it. Light Labs International, an independent lab, measured our lamps at 6 and 12 inches — the full report is under "Check the Specs" — and on our product pages, Robert Hunt, author of The Blue Light Diet, measures most of our devices on video with his own spectrometer.

Measured irradiance: 138.39 mW/cm² at 6" · 67.22 at 12" — our 200W COB, shared across the Inferno, Firewave, Firestorm, and Krypton lines
Flicker published for every model: 0% on Meanwell-driven PROs · 3.2% independently tested on standard drivers.

Kris, founder of EMR-TEK

Founded by someone who lived it.

Kris developed vitiligo at age 3. Twenty doctors said nothing could be done - it was his mom, searching library shelves before Google existed, who found the German researcher whose approach finally made a difference for him. Kris has spent the twenty years since trying to understand why, and the last eight building EMR-TEK.
