This video compares some of the most common power outputs of green lasers you can buy these days. I compare the difference in visibility and burning between 5mW, 15mW, 35mW, 50mW, 100mW, and 150mW.

Important info after watching this video:
-I used fog to bring out the beams.
-This video is only about green lasers because they are nearly always fixed focus and have a small beam diameter.
-I mention powers where tricks are EASY to do. You may be able to pull off burning tricks with less power than what I state, but these are bench mark powers where you can reliably do these burning tricks.
-Additional focusing with extra lenses can lower the threshold of what you need to burn. Watch my focus video for a better explanation of this.
-I go by actual power of these lasers in this video, not advertised. Nearly all cheap laser sites sell lasers marked from 100mW to 300mW when in reality the actual power is much lower.
