Question:
Why your lamps and not narrowband UVB lamps?
Answer:
Most UVB lamps emit 312 nanometers.
But this is not the best wavelength.
Because these lamps are fluorescent, they can produce only a fixed wavelength, since the light comes from electrons in atoms jumping between circles around the atom center.
When an electron jumps from one circle to another, it releases energy as light.
The wavelength of the light is determined by the distance between the circles.
The circles have fixed diameters, and that is why the wavelength is fixed.
This is the principle of quantum physics discovered by Niels Bohr.
With fluorescent lamps, you cannot tune the wavelength, and you are limited to 312 nanometers, which is not the medically optimal wavelength.
LEDs, however, can be made to emit any wavelength, including the medically optimal one.
We developed these LEDs. They work much better than the 312-nanometer lamps.
The wavelength we discovered requires a dose that is 300 times lower than that of 312-nanometer lamps. The medical results are better because we reduce the dose by 99.7 percent, and the skin does not receive unnecessary high UVB doses of 3 joules.
It is like tuning a radio to the exact station. Just as a radio can pick up a clear signal with very little power when tuned perfectly, the skin responds better when the light is tuned to the optimal wavelength.
And in numbers:
Using a wavelength of 312 nanometers requires a dose of 3 joules. This dose is six times higher than the dose that causes erythema, or skin redness, which is 0.5 joules.
To avoid erythema or skin burns, treatment should begin with a dose below 0.5 joules, for example 0.2 joules. With each session, the nurse gradually increases the dose, allowing the skin to adapt.
Over time, the skin becomes more tolerant to UV light. After about one to two months, it can absorb the full 3-joule dose without developing erythema or redness, and at this stage, the healing process begins.
With the introduction of new LED-based lamps, the required dose is only 0.01 joules, about 50 times lower than the erythema threshold.
Because of this low energy level, no nurse supervision is required for timing, the lamp can be safely used at home, and there is no need for large 6000-watt clinical booths since a 20-watt handheld LED lamp can treat the entire body at home in the same treatment time.
Question:
Why are your lamps better than narrowband UVB 312 nm (TL-01)?
Answer:
Narrowband UVB lamps have been used for many years, but they carry significant safety concerns.
To achieve a therapeutic effect with narrowband UVB, the skin must receive a dose that exceeds the threshold that causes DNA damage, clinically seen as erythema (redness) or even burns.
In other words, to obtain medical results, the skin is inevitably exposed to DNA-damaging radiation.

DNA damage increases the risk of developing skin cancer.
To put this in numbers:
The dose that causes erythema (DNA damage threshold) is approximately 0.5 joules.
With narrowband UVB (312 nm, TL-01), the therapeutic dose required to achieve results is 3 joules — six times higher than the erythema threshold.
This means patients must undergo skin redness and DNA damage in order to see benefits.
By contrast, our lamps are fundamentally different:
They achieve the same therapeutic effect at only 0.01 joule.
which is 50 times lower than the DNA damage dose and 300 times lower than the narrowband UVB dose.
This measurement is based on direct testing of the UVB light output of our lamps.
Treatment Dose Calculation:
The measured intensity of our lamps at the advised distance is less than 1 milliwatt per square centimeter.
The recommended treatment time over the whole body is 10 seconds.
Therefore, the delivered energy to the skin is:
Conclusion:
This dose is 50 times lower than the erythema/DNA-damage threshold of 0.5 joules per square centimter , while still achieving therapeutic effect.
The Advantages of Our Lamps
Safer treatment: The skin never reaches the threshold where DNA damage and burns occur.
No gradual dose increase: Unlike narrowband UVB, which requires starting at very low doses and slowly building up, our lamps can deliver the effective dose immediately.
Faster results: Patients receive the full therapeutic dose right away, significantly shortening the treatment timeline.
No side effects: No erythema, no pain, and no skin damage during therapy.
More efficient design: Because the required dose is extremely low, even a small, low-power handheld lamp can treat the whole body in just a few minutes.
This efficiency makes bulky full-body cabins with dozens of high-power narrowband UVB lamps unnecessary.
That is why our lamps are both safer and more effective than narrowband UVB.
They deliver high therapeutic benefit at only a fraction of the dose and price.
Question:
Hello, I found you on Reddit and am curious about your UVB handheld devices for eczema. Can you tell me more about you, your credentials, and why your device is superior? I suffer from eczema on my scalp, behind my ears, and below my armpits. I am about to start a new biologic called NemLuvio but want to exhaust all other avenues first.
Answer:
Our lamps are designed to work with the body’s natural processes.
They do not suppress the immune system or interfere with cell communication, as systemic biologic drugs (such as NemLuvio) do.
Instead, they provide a safe, localized stimulus that supports the immune system and helps restore skin balance without systemic side effects.
Because the therapeutic dose is far below the DNA-damage threshold, treatment is non-invasive, safe, and effective even in sensitive areas such as the scalp, ears, and underarms.
Question:
May I ask what wavelength your devices use?
Answer:
The exact wavelength is confidential, as it was determined after extensive testing and optimization.
Traditional fluorescent lamps (such as TL-01) are fixed at 312 nm, which is why all narrowband UVB devices use the same wavelength.
With advanced LED technology, however, we are no longer limited to one wavelength.
We are able to select an optimal wavelength for therapeutic effect while minimizing unwanted side effects.
This is one of the key reasons our devices are fundamentally different — and safer — than conventional narrowband UVB lamps.

Question:
And this device is safe to use long-term?
Answer:
Yes. The treatment dose is 300 times lower than the doses used in narrowband UVB, which means it is much safer for repeated and long-term use. Because the skin never reaches the threshold of DNA damage or burns, there are no cumulative risks like with conventional UVB therapy.
Question:
What medications can the lamps replace?
Answer:
Our lamps are designed as a safe, drug-free alternative for many chronic skin conditions. In many cases, they can reduce or even eliminate the need for:
Topical steroids (creams and ointments)
Topical calcineurin inhibitors (e.g., tacrolimus, pimecrolimus)
Systemic drugs such as methotrexate, cyclosporine, or biologics (e.g., NemLuvio, Dupixent), which often carry significant side effects
Because our lamps act locally on the skin without altering the body’s immune system, they can often achieve results without the risks and complications of long-term medication use.
