About EMR-TEK
Founded by someone who lived it — not someone who saw a market opportunity. Kris Sweeting was diagnosed with vitiligo at age 3. By 5, he was in UVA phototherapy. At 9, with the condition spreading and conventional treatment failing, his family took him from Canada to Germany to consult Dr. Karin Schallreuter at the Institute for Pigmentary Disorders — the researcher who pioneered the pseudocatalase + narrowband UVB protocol (Philips bulbs, 311nm). He ran it daily at home. Near-complete repigmentation, with only a few spots remaining on his hands and feet. By 14, he was printing PubMed studies in his basement. By 18, he was self-studying photobiomodulation, endocrinology, and circadian biology. Eight years building EMR-TEK, every device used on himself first, every protocol run personally.
That experience left him with one conviction: most of what gets sold as light therapy is the wrong hardware marketed with the right words. He built EMR-TEK to fix that.
Individual results vary. EMR-TEK devices are general-wellness products, not medical devices.
Why EMR-TEK
Here's something the industry doesn't want you to know.
Most of the panels on the market are the same product. Same Chinese factory. Same circuit board. Same actual specifications — regardless of what the marketing page claims.
Different logo. Different price tag, depending on how much the influencer deal cost.
I know because I looked at all of them before I built my first device.
Standard LED diode arrays scatter light. Wide emission angles. The irradiance — the actual photon density reaching your tissue — drops fast with distance. Most panels that claim to deliver meaningful output at six inches away can't when you actually measure it.
What's different inside every EMR-TEK device.
EMR-TEK uses COB (Chip-on-Board) technology: multiple diodes concentrated into a single emitter, paired with a cone-shaped optical lens. The result is dense, directed light that maintains irradiance at the distances people actually use these devices.
At the panel face, EMR-TEK devices read ~14,500 mW/cm². Most competitors read ~200 mW/cm². That is not a rounding error.
- Mean Well® industrial-grade power drivers — the same standard used in medical and industrial equipment. Not the generic knockoffs that cause flicker, voltage instability, and degraded output. Stable, measured, consistent.
- Philips 311–312nm narrowband UVB bulbs — the most clinically studied UV source in the world, present in virtually every phototherapy study published in the last 30 years. Not generic UV diodes. The exact bulbs the research was done with.
- Zero flicker. Zero measurable magnetic field. Every device is tested before it ships.
- Independently verified irradiance data — not self-reported specs printed on a box.
- A granted patent — not a pending application. Patent examiners don't grant in heavily-examined categories without rigorous review.
Who's using it.
Ben Greenfield. Dr. Jack Kruse. Khloe Kardashian — who bought six devices for her family and posted about it publicly. The Office of the President of El Salvador. None of them were paid. No PR agency. They used the products and said so.
That's the kind of proof you can't manufacture.
