Krypton UV 606W Full-Spectrum Light System

Red · Near-Infrared · UVA · 311nm Narrowband UVB | Compact Full-Spectrum System | Patent Granted

The Krypton line was built around one question: what does a serious full-spectrum light system actually require? Not bigger wattage claims, but the right architecture: COB technology at the center, Philips UV bulbs, Meanwell industrial drivers and independent control over every spectrum. The Krypton UV 606 is that architecture in compact form. It has four spectrums in one modular unit, the full Krypton design standard at half the footprint.

Full body from a compact panel: Sit cross-legged in meditation pose 24 inches in front of the 606 and your entire body sits inside the light, from head to legs. At that distance the beam spreads wide enough to cover you without a bigger panel. For more concentrated sessions on a specific area, move in to 12 inches.

Measured, not guessed: how we set session times

Most brands give you a session time with nothing behind it. Here's ours, step by step.

1. We measured the light. Robert Hunt, author of The Blue Light Diet, measured the 606 on camera with his own spectrometer and everything switched on. At 12 inches it puts out about 30 mW/cm² of red and near-infrared light (6.1 red + 23.6 near-infrared). That number is its irradiance: how much light power reaches each square centimeter of your skin. You can watch the full test in the gallery above.

2. We checked it against the research. Michael Hamblin's group at Harvard Medical School and Massachusetts General Hospital reviewed the light therapy literature. They found most studies use an irradiance of 5–50 mW/cm² and a dose of 1–20 J/cm² (Huang, Sharma, Carroll & Hamblin, Dose-Response, 2011). The 606 sits inside that irradiance range at both 12 and 24 inches.

3. We did the math. Dose equals irradiance multiplied by time.

4. Why not longer? The same research found that red light follows a biphasic dose response: past a certain point, more light does less, not more. So longer isn't better. The right dose is.

UV is dosed by your skin, not a fixed time. In the same test, Robert measured 0.162 mW/cm² of UVB, peaking at 312nm, and 0.291 mW/cm² of UVA, peaking around 370nm. He noted that the UVB output is in the range of the most popular UVB machines on the market. Clinical phototherapy doses UV by skin response, because sensitivity varies so much from person to person. Start with the shortest session in the manual and build up gradually. Your threshold is the first sign of light pinkness; if you see it, hold or shorten your next session.

We publish our measurements, and our estimates labeled as estimates, so you get real session times backed by research, not a number we made up.

The same COB at the center: Every Krypton runs a COB (chip-on-board) at its core: chips bonded directly to a substrate, with no housings, no gaps and no scatter. The 606's 200W COB is the same module used in our Firewave and the Krypton 1612. Light Labs International, an independent lab, measured it at 138.39 mW/cm² at 6 inches, directly in front of the chip. Around it, 64 × 3W LEDs extend coverage and let you run red and near-infrared without the COB's full intensity.

What each spectrum does:

630nm · 660nm red · near-infrared. These match the absorption peaks of cytochrome c oxidase, the mitochondrial enzyme at the center of photobiomodulation research. Red light is absorbed in the dermis and studied for its effect on fibroblast activity. Near-infrared penetrates several centimeters into muscle, joint and connective tissue. Robert's test showed more near-infrared than red, with peaks around 820 and 850nm.

UVA, peaking around 370nm. UVA is present year-round in natural sunlight. It penetrates deeper into the dermis than UVB, reaching the vascular layer, and it's been studied extensively for its effects on skin cells, melanin and the circadian system.

311nm narrowband UVB. All UVB can damage DNA. That's true of sunlight too, and it's the honest starting point for any UV conversation. Broadband UVB spans the whole 280–315nm range, including the wavelengths that do the most damage for the least benefit. Narrowband is the answer researchers arrived at after decades of work: isolate the single wavelength, 311nm, where the intended biological effect is strongest and the mutation rate in skin cells is lowest, and deliver only that. Less of the spectrum, less of the damage, same effect. That's why clinical phototherapy standardized on 311nm, and it's the only UVB the 606 emits.

Philips bulbs and Meanwell drivers, and why we don't make our own: Every UV bulb in the Krypton line comes from Philips, the Dutch company that has made phototherapy lamps for decades. Ours are imported from their production in Poland. The 606 runs two PL-L 36W/01/4P UVB tubes and two PL-L 18W/10/4P UVA tubes: the same bulbs as the 1612, at half the count for the smaller footprint. The reason is spectral consistency: a tube that says 311nm delivers 311nm, whether it's this tube or any replacement.

We could manufacture our own bulbs for a fraction of the cost. We don't. Our founder Kris grew up under Philips tubes. They were the bulbs in the clinical narrowband UVB protocol he went through for his vitiligo as a kid, and his rule hasn't changed: he won't put a component in an EMR-TEK device that he wouldn't stand under himself.

Meanwell industrial-grade drivers are standard across the entire Krypton line, not an upgrade you pay extra for. In Robert's live test, the 606 showed a flicker index of 0.00; his verdict was "virtually flicker-free." Where a specialist already makes the best component, we buy it rather than build a cheaper one.

Independent control, modular by design: Red/NIR, UVA and UVB each run under independent control: one spectrum at a time, stacked, or all at once. The 606 also connects with other Krypton units. Run it alone for full-body seated sessions or targeted work, pair it with a 1612 for even more coverage, or build out a dedicated light space over time. If you're deciding between the two, the 1612 is the full-body foundation for standing sessions, and the 606 is the same design in a compact panel. Because the line is modular, choosing one doesn't close the door on the other.

Does it work internationally? Yes, but differently than our panels. Our panels have a built-in voltage converter. The Kryptons don't, because the Philips bulbs need exact electrical specifications. Instead, we build each unit for its destination: order from your region and your Krypton arrives matched to your grid. There's nothing to configure and no adapter to buy.
