Lasers Vs LEDs

There are some laser therapy products on the market that contain LED’s (Light Emitting Diodes). These products usually claim to provide superior treatment results and effects than those achieved with lasers. Whilst monochromatic, non-coherent light is useful for treating superficial wounds, research studies over the years show that lasers are more effective in treating this condition. This is due to the unique properties associated with laser light, resulting in deeper penetration depths. Many LEDs are low powered, say 5mW-15mW, with the result that energy is scattered, thus requiring longer treatment times. LED’s normally penetrate less than 1cm into muscle tissue, whilst infrared lasers, eg 830nm, penetrate up to 5cm. This proves once again that lasers are the best form of light therapy available on the market.
