Violet blue laser's visibility is not that obvious as green laser, red laser or blue laser beam because of the insensitivity of 405nm beam to light, and its beam only becomes relatively bright or visible when it reaches >50mw, and it's visible in ultra dark conditions, and the laser beam is more than bright and exciting if you see it from the opposite direction. 120-200mw violet blue laser beam is able to light match, cigarette and papers easily. Don't forget to use its FOCUS ADJUSTABLE function.
