Attached this flashlight to my laptop with a suction cup (not included) and used it for zoom. Excellent quality of light, very bright. The diffuser (included) is a must if you use it with the webcam. My only complaint is that the diffuser cap falls off very easily. Not a problem when the light is there, but can be a problem in the field. Battery life is adequate considering how powerful the light is. In general very satisfied!
