• Advantages of light-emitting diodes (LEDs) are:

o  High electricity/light conversion efficiency

o  No filaments: no flash lamps

o  Can be mounted in large area planar arrays (maximizes photon intensity)

o  Quasimonochromatic.

• Advantages of LED-LLLT (low-level laser [light] therapy) are:

o  Non-laser, non-invasive, non-ionizing

o  Can be applied by a trained therapist

o  Pain-free treatment

o  Side effects free

o  Well-tolerated by patients of all ages.

• LED-LLLT enhances the wound healing and remodeling process.
• 830 nm LED-LLLT provides prophylaxis against hypertrophic scars.
