At Home LEDS vs Professional Grade LEDS
How to tell the difference:
1. Home use LED light therapy devices that I have found do not go over 30mw/cm2 and usually have about 300+ diodes per treating area. A 60mw/cm2 model should have about 1000 to 1200 diodes per area being tread. 80mw/cm2 models have very compacted LEDs and have at least 2 of the 3 latest LED technologies. They are smaller in size than the earlier generation LEDS. Many people think they can buy a home use LED light and it will be like the one in the clinic. It is not just having the cheaper LED device take longer but usually the wavelengths of their infrared are not even the same wavelength on the infrared spectrum. Just like not all infrared saunas produce the far infrared isolate that people think they are paying for. The home use LEDs do not typically penetrate as deep as the LEDs in the clinic. This is why so many people return them. The companies that have it in bold that you get a 30 day money back 100% money back trial are usually the ones that are the lowest end of the brands I reviewed. No company wants people to get stuck with their product and write bad reviews on the internet and then no one will buy them.
Note: all the studies that some companies are bragging about were not done on their brands. The clinical grade models that have higher doses are the ones with all the studies so when a LED light company claims LEDs do this and that but not backing it up is a big red flag to me. But of course, the ones that were done during studies that have many FDA clearances will cost more.
2. LEDS that are clinical grade and have the latest LED technologies will have shorter session times. Many people want their treatment time as quick as possible. Practitioners usually buy the highest fluence models as they want to treat more patients per day and want to clear up their patient rooms.
Newest Generation Diodes- Latest type LEDS
The most expensive LEDs will have the highest fluence per diode. The residential diodes are more typical of the standard diodes that cost a few cents per diode. The newest LED diodes can produce more up to 120mw/cm2 with minimized blood reflection. (note: this is not the super luminous diodes that have high wattage that the blood in the body will just reflect the light).
Some brands have 150 to 200mw diodes and they are the older generation LED diodes that don't have the SMT diode technology that was not around when the super luminous diodes came out. At that time, that was the best in LED light therapy.
The latest to look for that many LED devices have are the PureLED(™) Technology trademark and the StimuLED(™) LEDs. Unless it says it has these it is not the newest generation of LEDs. (When I tried the laser that had both in their diodes it was a night and day difference between the brand that I first used that didn't have this. Back in the day, they didn't have this and is why LED's took so long and weren't as effective as lasers.
Scam watch - Higher Wattage LEDS (Some brands have LED light therapy devices that have way more wattage than all their competitors. These are usually the knock off brands that are cheap on the market. If the LED is too powerful the light will reflect off the blood and will not be therapeutic.
Residential LEDs (both can work but the residential ones take much longer.
My requirements for any LED to be considered built for a medical clinic or used in any commercial setting.
1. Must have a metal frame (most residential ones crack and break in offices made of plastic)
2. For estheticians, I only recommend LEDs that have a minimum of 90 joules cm2 or
100mw per cm2. Basically, for the face if it has less than 1800 to 2400 diodes, it is not fair to the patient as they won't be getting enough treatment. (Note: LED light therapy beds usually have about 40mw to 50mw/cm2
3. Wavelengths - For patients paying per session, usually its because they can't afford a 10,000 to 20,000 dollar LED device. The higher end LED light therapy devices have dual red wavelengths and dual infrared, not just one diode that delivers one red wavelength.
4. Must have zoned off LED diodes. So, if one diode goes bad and the diodes are not zoned off in groups, you have to replace or send back the entire unit. So, if a unit has 1800 LEDS, and a block of diodes went out, just the block of those can be changed.
