Does a laser sight by itself, either red or green, provide enough illumination to distinguish targets in a low-light (dark room) situation?

Depending on how powerfull the laser, how well the beam is focused and how far away the target is yes. will you be able to tell if it it your brother or a stranger yes at 20 ft will you be able to tell what color their eyes are no. lasers are not designed for illumination. If you are tring to just light up the person without lighting up the area try a blue or red navigation light in the less than 5 lumen range.

Thanks, I think that tells me what I need to know. I'm trying to determine if equipping my Glock 19 with only a laser sight (such as the Lasermax), rather than a laser & light combo, is enough light for detecting and identifying intruders in a home defense situation.
