BG234955351 Don'thave any device to measure that, it is quite bright, maybe even manufacturer description of 3000 max is correct (three levels in total) ,nice wide and even area light no hotspots, magnets in handle not strong enough but easily can be changed for thicker, not sure how long hook will last, battery adapter can be removed and light used with ac-dc power adapter(not included) - so it is a hybrid light.
