Hi realdoggymouse,

Well there are a few differences, One is that a laser can operate at a much
higher power level than an LED, does not mean that all of them do however, most
small lasers put out 5mw or less, LEDs can do mare than that. A laser puts all
the light on one small spot so the concentration is much greater, but then if
you have treat a large area it may take a long time. LED can cover a large area
at once. You can get LED units much more readily than laser units.
Leds are safer there is no over doing it in most cases. with a laser you have to
know how much time to use it so you don't over do it.
A strong laser can be expensive compared to an LED unit also.
LED units can be made in more variety of colors for various applications than
lasers can.
So it all depends on what you want to do and how much you want to spend. If you
have a serious inner ear problem for example a laser may be best due to its
ability to keep the light focused and higher power, but if you want to sooth
sore muscles then an LED unit will probably work better.
It all comes down to the right tool for the right job.

Oh and a laser has a more precise frequency than an LED, a narrower range.


Take care,
V
