Although frequencies can be added, a laser that worked yesterday will not be obsolete or outdated. Nothing new except for non-inhibiting lasers has just come out. The institutes and research studies are funded by the companies. Companies will never publish a study not in their favor and without objectivity. There are honest, earnest sellers and there are sheer liars. The class 3 sellers have their opinions based on their studies and are going to extremes to show you that a class 4 laser is not the best. A class 3 and class 4 sellers can both be right but you need to know what studies and examples they are basing their theories on. Will a class 4 laser burn you as the class 3 sellers claim? Well, you can hold any light with heat "still" for a minute or put your hand over the stove and it won't burn you but hold it still and you will see what this theory is based on. NO! If used properly, a class 4 laser cannot burn you. Does it yield better results from its high power? That depends on what the demands are for.

Class 4 lasers do penetrate the deepest into the tissues but this depends on the TYPE of tissue being treated. I do not go by the pictures on some class 4 laser websites because it can be misleading and outright manipulating the truth. Even doctors that have studied the body can get scammed and this is sad because clients trust them and depend on the doctors to know their lasers. How deep their class 4 lasers penetrate not only depends on the type of tissue but the treatment techniques and how the technician uses the laser at different power settings.

Higher powered class 4 lasers offer many advantages over class 3 lasers as well as lower power class 4 lasers. The strongest lasers have more room to burn people but take the shortest time while the lesser powered ones take longer and a doctor can't see as many patients per hour with it. In a high volume clinic, where there are several doctors using that laser and trying to schedule as many appointments as possible, they will have to decide on how strong of a class 4 laser they need based on how many patients they expect to use it daily and how much time they can use it on each patient. More power has proven to get better results with stubborn conditions like neuropathy, spinal stenosis and disc herniations. 

Choosing a Pulsed Class 4 VS a Continuous Class 4 Laser
The pulsed laser is much different than the continuous lasers. The continuous class 4 lasers are designed for serious failures, not just "oh, my lower back hurts from sitting at my computer every day or waking up on the wrong side of the bed". It seems that only the elite pain clinics have these and they charge way more for their sessions which make these unaffordable for most people. If doctors can't afford the price point of the continuous lasers and are buying lower powered lasers and telling their clients to come back for more sessions than they would need if they had this type of laser, it is unfair to the patient. The patients that need fewer sessions usually call me with their success from the continuous class 4 lasers. The continuous laser is far more expensive than the pulsed, usually 17K and up. Most doctors just starting out cannot afford these and most of the people calling me for cold lasers are trying to catch up with the senior chiropractors and other doctors who have success with these lasers and are trying to get in on the niche. I am sorry but it is not cool when a doctor uses some weak laser and charges the client the same as those with the continuous class 4s. Sure, if a doctor pays 35 to 50 grand for a top end laser, they can charge the market price.

The continuous lasers are great when the situations are serious. Just having tightness in your hands shouldn't demand this type of lasers. The continuous lasers aren't as advertised as the pulsed probably because there is a lot more training involved with these, not that I am saying you don't need training with the pulsed class 4s. The high traffic clinics who have untrained high turn around technicians typically won't have the continuous lasers. Again, most clinics with doctors just starting out won't have lasers that cost 35k or more or at least very rarely.

If you are a client that is seeking class 4 laser therapy, honestly, I would only get the treatment done if it is done by a doctor who has BEEN TRAINED to use that laser or technicians where have been qualified. Class 4 lasers are a different breed than the class 3. They work quicker but come with their own pros and cons. The class 3 lasers are not better or worse than class 4 nor is pulsed than continuous. They all work. It is just what is the application you are using it for and your needs of your clinic and the demands for the laser in your clinic. I have found that those with the class 4 pulsed have something to say about the continuous and the doctors that have the class 4 continuous always have similar things to say about the pulsed ones.









Difference between Continuous Wave (CW) and Pulsed laser
Most lasers are so called "Continuous Wave", abbreviated CW. CW lasers are on or off, just like a flashlight.
Some higher-end cold laser devices allow the user to select modes where the lasers diodes flash on and off.  This is not to be confused with super pulsed lasers, where the pulsing is the required method of controlling the laser diode. (This type of pulsing is usually at hundreds of thousands or millions of times per second.) The pulsing discussed here is low frequency, from less than one hertz (one flash per second) to tens of kilohertz (thousands of times per second). Often the pulsing is slow enough for you to see it.
Some clinical studies have found that the therapeutic effect of pulsed laser is significantly greater than CW treatment. However, having the correct frequency is just as significant. On study I read found a significant improvement when using infrared pulsed at 10Hz (compared to CW). However, the same study found that the effect at 100Hz was no different to CW.
Do you need pulsing?  Many users of pulsed LLLT devices will attest to the value of having the pulsing function, especially when used for diagnostics. Since the body responds differently according to the frequency, this characteristic can be exploited to quickly hone in on a particular ailment. It is fare to say that a pulsing feature adds to the usefulness of an LLLT device, but bear in mind that using this feature effectively will require more advanced training.

Square wave, sine wave and complex waveforms.
Most pulsing LLLT devices modulate the laser diodes so that they are either on or off. As a function of time, this is represented as a square wave, with rapid transitions between the off and on state. Some devices modulate the laser diodes so that their energy output follows a sine wave form. Square wave and sine wave output devices offer a range of programming capabilities, including the ability to produce pulses of a single frequency, multiple frequencies, or scanning through a range of frequencies. Some devices even offer the ability to output multiple frequencies at the same time from a single diode. This is sometimes referred to colloquially as a "scalar wave" (a non-scientific term). There is insufficient research to meaningfully compare the efficacy of these different technologies. 

My prerequisites for selling Class IV Lasers
Must be FDA cleared
Must work at "true" class IV Settings 
Must be "stimulatory" to deep pathologies 
Must have new divergent beam technology if continuous powered to avoid burns
Must state "burn" cases and documentation upon request
Must be currently in at least 100 chiropractic clinics
Must be currently in at least 75 veterinarian clinics
Company must already be around 5 years or longer
Must be made in an ISO-13485 approved manufacturing plant

NOTICE:
Not all Class IV lasers are the same. A 500 Milli-Watt laser can be reduced to 300 watts after transferring through the optics. Better optics give better output power. (See my write up on peak output power versus phony output power, real constant output.) 
Note: With non-inhibiting lasers, it does not matter about the power. If "ANY" light touches the body or substance, even if the light is very weak from a nearly dead battery, it does not matter. The light is only a carrier wave. Just one photon is enough to transport frequencies carried by the laser. This is why you can shine the laser through clothes and it still works. 

Negative Photo Destructive Light Reactions:
Very similar lasers used in laser surgery that can destroy cells and cut and burn, be cautious with some of the lasers in this class. You do not want to shine a laser to inhibit pain to the point that the cells being shined cannot survive the thresh hold that is not in the parameters of that laser. The cells in the body can be destroyed by too intense of light and even burned to the point that even time cannot help and the destruction is irreversible. Please study the difference between inhibiting lasers and non-inhibiting lasers. They both can work great but work in 180 degree opposite ways.

A lot of doctors get free trials and it seems they usually end up buying the one they had a trial with. What is interesting, and I will use chiropractors as an example, if they had 3 lasers sent to them, they almost always pick the first demo. All of the class IV lasers work, it is just that some work on different settings than others and give different results. What I did notice is that those who get demos which add expense to the manufacture, end up paying more for their laser than those who already know what they want. It is sad as I have mostly chiropractors call me up all the time and ask me what the best price they can get a Class IV laser for. When I ask them what price they were quoted, I rarely get someone who tells me the same price. Buying a Class IV laser is like buying a car. There are dealers and there are the manufacturers. If a manufacturer has dealers, you are most likely to get a different price as the manufacturer typically has prices they won't compete with their dealers so they usually don't discount. Another thing I have noticed, is that if a dealer is talking to someone about a class IV laser, they will contact the manufacturer so they won't take their sale.

If you are NOT already talking to another Class IV laser dealer, feel free to contact me. I will not discount a Class IV laser if you are already talking to another manufacturer's authorized dealer. If you are talking to the manufacturer and are NOT already working with someone I will help you get a better price. I will not discount a Class IV laser knowing that you are trying to bypass one of the manufacturer's dealers. If you have been sent a demo and want to get a laser, YOUR NAME is probably already in their system and I will not steal their sale.

CLASS IV LASER BUYING ADVICE
Beware of misleading physics when buying a Class IV Laser. A 10 watt or even a 20 watt laser that a company claims it has might not be accurate. We had to test these lasers in order to find out what we weren't being told. I interviewed some of the people that used to work with Class IV companies that started their own companies and I learned things that conflicted what the spec sheets and sales people have told me.

10 Watts of power will give a certain penetration so why the F@#% does a 7.5 watt laser penetrate further than a 10 watt class IV laser. Or how can a 15 watt laser penetrate almost double what a 12 watt laser can. If a patient goes in and wants a therapeutic dose and the laser doesn't deliver it, THAT IS A SCAM!.

With the Class IV lasers that I have found, there are two types. Continuous, those that work on a continual basis and pulsed ones,,that usually have a 50% duty cycle, meaning that they only work 50% of the time. But that is not the main issue. What makes the difference even more when it comes to specs that you can take word for word and literally go off the spec sheet, is that some Class IV lasers have single wavelenghts and the other type has dual wavelengths. Based on my tests which you can do simply with a bit piece of meat, is that each type has a different absorption and reflection curve depending on the power output. I also noticed that having two dual lasers that are the same power is not cumulative and doesn't penetrate more than a single wavelength. 

With  dual wavelength, only the laser that is the strongest does the job. So when I used a 10, 12 or the 15 watt laser, the penetration is cut by half. A 15 watt continuous wavelength that gives 15 watts on only one wavelength instead of being divided over two lasers is going to penetrate with half the power or go twice as much. This is how I found that a 7.5 watt continuous laser is more powerful than a 10 watt laser. This only matters if you need to penetrate really deep. If just for the hands, you don't need anything over 500 milliowatts and none of this matters. With recent technology in class IV lasers, lasers are now trending towards continuous single wavelengths. Although the are more expensive, you can get twice the power or you can buy a laser that is lower wattage and continous that can equal out to a laser that has twice the power but is pulsed. It gets very confusing and most people just look to see which laser is the most powerful without learning this stuff and end up over paying.

Notes to add: new research
Killing the cells... if putting toot much energy is apostasis. (Killing of the cell...photo-bio-inhibition, the opposite of photo stimulation.. instead of stimulating.. its killing the energy producing part of cell does off.. not good.

If you want the cells to function at a higher level, don't do this
When to get higher wattage: Maximum power should never be over 7.5 watts in 10 minutes (dosages)

 2014 Class IV Laser Review
Class IV LASER Buying Option - Attention anyone wanting my cost on a Class IV laser.
In order for one of the reps to fly down, get a hotel and stay for a few days letting your patients use the laser for free to demonstrate it, I either get standard wholesale or a much deeper discount if I pay the cost for someone to fly down and show you the laser. Every 10 times I pay $600 which I have agreed, usually 2 people buy. Every time people pay for it, almost everyone buys. That makes the price of the laser much cheaper. If you are serious about buying a laser, and want to try it which most companies require you to get trained first, pay my cost up front to show your commitment or keep searching the net. Remember, I only will give my dealer cost if I have no risk to put out first. I do not profit $600, it goes directly to the manufacture. I get either 25% or 40% off retail. I will only take 5% over my cost depending on which way you go.

To Cold Laser Store:

REGARDING CHIROPRACTOR

>He is not buying the laser - but the owner of the clinic would be the one buying

> I had some initial calls with this office to get things set up - and then answer questions

> I met at their offices and treated patients for 8 hours over 2 days

> I have had 4 followup phone calls that reviewed a number of questions - including another call early this morning

> They want me to come back on Saturday to treat one of their staff - (another trip - pretty common request - to see if the results are the same "again")

> They are applying to a leasing company to buy the laser

> They are looking at buying a 10 watt for 20% off. The list price is $13,900 - so we had to offer a discount - which affects our margin

> We have to set up a DAY to install and train their staff on the laser - after they purchase it

> We have to help them with getting set up for marketing - again TIME - to do this - get their website updated with lasers, set up their inhouse marketing, etc,

Bottom line: There is alot involved.
THIS IS WHY OTHER LASERS - ie for Aesthetics cost $20,000- $30,000 - it takes alot to demo and train! Especially airline tickets and hotels, and paying the sales staff
The other laser companies are doing onsite demos - - the ONLY way to sell against this - is to SHOW YOUR LASER - and they can SEE the differences.
You can't just mail a laser to someone and then have them use it to "try" - it is not a toy. There are alot of medical treatment considerations. You cannot discount our lasers even if they will buy it. Problems arise which cost us money in time, not you. It always happens like this. The last 6 of our lasers that you sold had no idea how to program them and we had to cover that expense.

Thanks!
Ben

PS
Normally we pay a 25% commission to a rep that does it all.
We offer a 40% margin to a distributor that DOES IT ALL - and INVENTORIES product - and does CUSTOMER SERVICE, etc. before and after the sale.

So - if I pay you guys a 15% - and then pay 10% to a sales rep - who demos it, then closes it, then installs it, then trains it - and he gets 10% (25% - 15% = 10%) - it is not equitable

We can pay 10% finder's fee - that is fair and reasonable. I would like to see other companies match this??

For anything above this - You guys would have to PROVE that you can provide everything needed to make and close a sale. In 2013 I expect you to either find your own staff to train anyone who purchases our laser or be happy with your finders fee. I am happy to give 40% off if you meet our expectations.


PSPS
The bottom line is that to provide "product reviews" - you have to be either a) a laser expert or b) involve laser experts.
A LAY person cannot do this - it is just WRONG.

The door is open for us to work together - BUT - it has to be done the right way and OUR way.
At the end of the day - it is the customers knocking on our door - and we have to be responsible at all times.
