The 10 Essential Factors of Choosing a Laser
Not all lasers are the same. Before price. Before brand. Before appearance. Ten factors separate a system worth investing in from one that will underperform. The PRO VX was built with every one of them in mind.
— UNDERSTANDING LASER LIGHT —
Laser light is not just light. It is precision.
Laser stands for Light Amplification by Stimulated Emission of Radiation. Unlike ordinary light that scatters in all directions and fades at the surface, laser light is coherent and precise. It stays organized as it travels, which is what allows it to penetrate deeply and interact with the body in targeted, meaningful ways.
This distinction is what makes photobiomodulation possible. Specific wavelengths and pulsed frequencies work together to support natural cellular processes, including ATP production, the body's primary source of cellular energy. The result is a technology that works with biology rather than around it.
Precision is the key. Wavelengths, frequencies, power, placement, and timing all have to align for a laser to perform at its potential. Not every device that produces light is capable of this level of design. That is why we outline ten essential factors to consider when choosing a laser.
Dive into the science behind photobiomodulation and the 10 Essential Factors of choosing a laser. Select a section below to jump to specific studies and findings.
COHERENCE
01
Laser Coherence
The most fundamental distinction between a device that works and one that does not. LEDs and lasers are not the same thing, and the difference goes far deeper than marketing language.
LEDS ARE NOT LASERS
LEDs produce non-coherent light that scatters in all directions and fades at the surface of the skin. They are useful for surface-level applications but they cannot deliver energy to deeper tissues in any meaningful way.
Lasers produce coherent beams that stay organized as they travel. Because of this, a laser can maintain its intensity and deliver energy several inches into the body. This is not a marginal improvement. It is a fundamentally different mechanism.
The PRO VX is a Class 3B therapeutic laser. Every diode produces coherent light at a precise wavelength, delivered with the consistency and depth that photobiomodulation research is built on.
WHY IT MATTERS
Without coherence and penetration, light cannot reach deeper tissues or provide meaningful results. This is why LEDs and light therapy devices cannot be considered lasers.
REGULATION
02
FDA Clearance
FDA clearance is not a marketing badge. It is a regulatory distinction that separates reviewed, tested medical equipment from general wellness gadgets.
WHAT FDA CLEARANCE MEANS
FDA clearance means that a device has been reviewed and meets strict safety and performance standards. This distinguishes it from devices that have not gone through the same regulatory process.
Blue Honest Inc. is FDA cleared. The PRO VX is cleared under this same standard, meeting the requirements for safety and reliability that practitioners and buyers can reference with confidence.
When comparing laser systems, FDA clearance is one of the first filters to apply. It immediately separates devices that have been held to a regulatory standard from those that have not.
WHY IT MATTERS
FDA clearance separates regulated medical equipment from general wellness gadgets. It gives practitioners and buyers a reliable standard to reference.
SPECTRUM
03
Wavelengths and Nanometers
Every wavelength of light is measured in nanometers. These numbers define both the color of the light and how deeply it penetrates into tissue.
THE FOUNDATION OF LIGHT
Every wavelength of light is measured in nanometers (nm). These numbers define both the color of the light and how deeply it penetrates.
Most therapeutic lasers rely on just one or two wavelengths. For example, 808 nm infrared penetrates well, and 635 nm red is strongly absorbed by the body. But stopping there limits the laser to pain and inflammation.
The PRO VX includes a full spectrum of diodes across violet, blue, green, red, bright red, and infrared wavelengths. This range makes it capable of supporting regeneration in addition to pain relief³.
WHY IT MATTERS
Wavelengths and nanometers may be the most important factor in a laser, because they determine how the body absorbs and responds to the light. The difference between one wavelength and six is the difference between a device that addresses one thing and a system that supports the body completely.
COVERAGE
04
Number of Laser Diodes
The effectiveness of a therapeutic laser is not only about wavelength or power. It also depends on the number of diodes working together to deliver energy consistently across the application area.
THE ROLE OF LASER DIODES
The effectiveness of a therapeutic laser is not only about wavelength or power, it also depends on the number of diodes working together. Each diode emits a precise wavelength, and when combined, they expand coverage and accelerate results without creating excess heat¹³.
Different diode arrangements determine how evenly energy is delivered to the target area. With too few diodes, the light can be uneven and less efficient. With a balanced array, coverage is broader, treatments are faster, and the energy penetrates more consistently¹³.
WHY IT MATTERS
A higher-quality laser balances the right number of diodes with the right output, ensuring consistent depth and coverage while maintaining safety. Too few diodes means uneven delivery and inconsistent results. The PRO VX uses fifteen diodes across six wavelengths to ensure every session is balanced and repeatable.
PRECISION
05
Pulsed Frequencies
Every living thing oscillates at specific frequencies. This is true for every tissue in every human, animal, and plant. Pulsed frequencies allow the laser to align with those natural rhythms and deliver with a precision that continuous wave devices cannot achieve.
THE ROLE OF LASER DIODES
Music is created and heard through frequencies, chakras are frequencies, and your telephone, radio, and television all tune into frequencies. Every living thing on earth - including every tissue in every human, animal, and plant - oscillates at specific frequencies. This is also true for bacteria, viruses, protozoa, parasites, fungi, and mold.
If you want to “dial in” a laser to perfection, you need pulsed frequencies that correspond to what you want to enhance or eliminate. The Blue Honest PRO VX incorporates 736 total frequencies, making precise targeting simple and effective.
WHY IT MATTERS
Pulsed frequencies allow the PRO VX to be tuned to specific biological needs. Without them, a laser delivers constant light, useful but imprecise. With 736 pulsed frequencies across human, animal, and plant protocols, the PRO VX supports with a level of precision that continuous wave devices cannot match.
OUTPUT
06
Laser Power Output
Power matters. But more is not always better. The correct balance of visible and infrared output is critical for both safety and performance, and getting it wrong in either direction means the device underperforms.
THE PRO VX POWER
The PRO VX integrates 15 diodes with a total output of 1110 mW. This combination disperses energy safely across the full spectrum of light.
-
4 Red (635 nm) at 10 mW each = 40 mW
-
2 Bright Red (670 nm) at 10 mW each = 20 mW
-
4 Infrared (808 nm) at 250 mW each = 1000 mW
-
2 Green (520 nm) at 10 mW each = 20 mW
-
2 Violet (405 nm) at 10 mW each = 20 mW
-
1 Blue (470 nm) at 10 mW = 10 mW
This design allows the laser to penetrate several inches into the body and disperse broadly within seconds.
WHY IT MATTERS
Balanced power ensures maximum penetration and therapeutic benefit without generating heat damage or exceeding safe thresholds. Both underpowered and overpowered devices underperform. The PRO VX delivers 1,110 mW balanced precisely across fifteen diodes to stay within the optimal range.
DOSAGE AND DURATION
07
Timing
Laser therapy follows the Arndt-Schulz Law. Too little energy produces no effect. Too much cancels the benefits. The therapeutic window is precise and both sides of it matter equally.

THE BELL CURVE RESPONSE
The Arndt–Schulz Law is best understood as a bell curve. At low doses, no tissue response occurs. At very high doses, stimulation is suppressed. Between those two extremes lies the optimal zone where the strongest healing response is observed²².
This principle has been demonstrated in studies of wound healing, where low doses showed no benefit, high doses slowed repair, and the optimal dose accelerated recovery²².
WHY IT MATTERS
Timing is as important as power. A properly dosed protocol maximizes benefit while underdosing wastes sessions and overdosing reduces effectiveness. Every protocol in the PRO VX has the correct dosage and duration pre-calibrated so the optimal window is managed automatically every session.
APPLICATION
08
Placement + Logistics
Even the most capable laser underperforms if it is not positioned correctly. Placement determines whether light reaches the right biological target at the right angle and depth.
Laser therapy follows the Arndt-Schulz Law. Too little energy produces no effect. Too much cancels the benefits. The therapeutic window is precise and both sides of it matter equally.
REMOVING THE GUESSWORK
If you have a specific area of pain it may be simple to know where to place the laser. But what if you have systemic pain all over your body. There are six spots that must be used and they are not where the pain is located.
Pain and inflammation are straightforward, but there are hundreds of other placement examples that would take hours of research to know. That work has already been done for you. You will receive a binder with detailed explanations, diagrams, and instructions for everything you need so the correct placement and setting is always clear.
WHY IT MATTERS
Correct placement is what converts a capable laser into consistent, repeatable results. Without proper guidance, even a premium device can underperform through misuse. The PRO VX placement guide removes the guesswork entirely.
VERSATILITY
09
Humans + Animal Protocols
The PRO VX is designed to work for both humans and animals. The protocols included are specific to each, bringing the same full spectrum cellular support to veterinary care that it delivers for people.
Laser therapy follows the Arndt-Schulz Law. Too little energy produces no effect. Too much cancels the benefits. The therapeutic window is precise and both sides of it matter equally.
HUMANS AND ANIMALS
The PRO VX is designed to work for both humans and animals. The protocols included are specific to each and show how the same technology can be applied safely across different species.
Settings are programmed with the flexibility to target human as well as veterinary applications. The system provides detailed guidance so practitioners and pet owners know exactly how to adapt the laser for either.
WHY IT MATTERS
Having both human and animal protocols in one device increases versatility and value significantly. The PRO VX is suitable for clinics and practices that serve both people and animals, and for households that want the same level of cellular support for everyone in them.
ENHANCEMENT
10
Herbs + Plants
A special capability that exists only within the PRO VX. Specific wavelengths align with chlorophyll and enhance the natural nutrients found in herbs, plants, fruits, and vegetables, whether ingested or applied to the skin.
Laser therapy follows the Arndt-Schulz Law. Too little energy produces no effect. Too much cancels the benefits. The therapeutic window is precise and both sides of it matter equally.
CHLOROPHYLL ENHANCEMENT
Chlorophyll is often valued for its antioxidant properties and potential health-supporting effects. The best dietary sources include green vegetables and algae, although cooking can lower the amount of chlorophyll they contain.
The PRO VX includes the correct wavelengths and frequencies to enhance chlorophyll, making plant-based foods, supplements, or topical products more effective²⁴.
WHY IT MATTERS
By incorporating these frequencies the PRO VX supports the natural benefits of plant-based nutrition and topical applications, creating an added layer of value beyond standard laser protocols. This capability is unique to the PRO VX and extends its usefulness into esthetics, herbal preparation, and integrative practice.
Technically, there is an 11th dynamic... and it is value.
Price is one thing. Value is another. The PRO VX delivers both. One device covering the full spectrum of photobiomodulation applications, human and animal protocols, and botanical enhancement. Compare what it would cost to build that capability across separate systems. The PRO VX does it all, and then some. We call it the last laser you will ever need.
