LED Lights Versus Laser lights

I've had a few queries about the use of laser lights. I can understand the allure of a laser, as its coherent light with such total focus is pretty impressive.

LED lights used to be very expensive. In the last decade the costs of LEDs have really dropped, and we can now buy them easily and inexpensively. LED lights are not coherent like lasers - the light from the average LED lights scatters and shines over a bigger area.

Question: For lights on the head, are lasers better than LEDs?

Answer: Nope.

Both have their place, but the previous dominance of laser lights is being whittled away by practicality and safety of LED lights.

For trans-cranial use, you want the red lights to scatter - you want coverage of the lights over the head. You also want to use the lights daily, safely and at home.

Lasers are a pain to use, they come with safety issues and they are not suitable for home use.

LEDs are the best.
