All lasers are not same:
Laser v/s LED:
Beware and do in-depth research before choosing a “so called” laser device.
LASER (wave length 650 nm, 5 mw) has been approved for safety as well as efficacy. However, patients wonder about difference in price of various laser devices. That is happening because some companies are passing off cheap LED lights.
e.g. if there is a helmet with 80 lasers.
To cut cost, some companies may install e.g. 60 LED & 20 lasers and sell at a fraction of cost.
LEDs are for Diwali/Christmas decorations. Do not fool people.
Those wishing to read the medical studies proving the laser’s efficacy may go through the studies carried out below.
It looks like this could be very dangerous…
what are you reffering to as a danger?
