After receiving the lights I put the batteries in and immediately clicked it on. Oh my! What a bright flashlight ! but I ordered a UV blacklight, didn't I ? Already feeling disappointed I jumped to conclusions that I had been sent the wrong item and proceeded to send it back. Then suddenly, after fooling with it for awhile I discovered all the features !!! ( i.e. the strobe, the wide/narrow focus and then the UV Blacklight which I was hell-bent on getting. All my disappointment vanished and now I am trying to figure out how to cancel my return. THIS PRODUCT EXCEEDED MY EXPECTATIONS !
