FlexBeam: I've Used It for 5 Years

How I Found It

Back in 2019, someone brought a weird-looking red light device to one of our biohacking meetups here in Chiang Mai. Having worked at Bulletproof Labs, I'd seen plenty of red light therapy devices — so I wasn't particularly impressed at first.

But I ended up meeting the founders. One of them, Christian, was deep into the same biohacking world as me. The science was solid. I became one of their early trial users alongside Dr. Frost, who's treated over 10,000 patients with light therapy.

Five years later, I'm still using the same device. Here's why.

What Makes It Different

Most red light therapy devices are flat panels you stand in front of. FlexBeam is flexible — it wraps around your knee, shoulder, lower back, or wherever you need it. You wear it. That changes everything.

• Legitimately portable — unlike most red light devices
• Wraps around problem areas — game-changer for knee and shoulder pain
• Built like a tank — 5 years of regular use, still going strong
• Actually powerful enough to work — 5.5W optical output, 10x more than competitors

What It's Good For

Red light therapy (photobiomodulation) works by delivering specific wavelengths of light — 660nm red and 850nm near-infrared — directly into tissue. This triggers cellular energy production, reduces inflammation, and accelerates recovery. The FlexBeam delivers this in a targeted, wearable format.

I use it primarily for joint recovery and chronic tightness. I've also seen people use it for thyroid support, gut health, and general inflammation reduction. The science is solid across all of these.

One Thing to Know

Don't use red light therapy in the same session as sauna. Sauna creates heat stress (hormesis) — that's the point. Red light supports cellular repair. Combining them blunts both effects. Use red light first, then sauna, or on separate sessions. This is the most common mistake I see people make with these tools.

Worth It?

At ~$550, it's not cheap. But I've been using the same device for five years. Sometimes the best biohacks are the simple ones you actually stick with.

They offer a 60-day money-back guarantee, so it's risk-free to try. If you're in Chiang Mai, reach out — I'm happy to show you how I use it.
