I bought this light and regret it beyond all belief . the white lights are so dim you can't even see they are on so reading anything is impossible . iv been back and forth from Bowmanville to depot four times because of this light . first due to missing parts, second due to the lights being so dim but the new one they gave me is even worse. Then when they replace it they forget to put the screws back in for the mount . so I had to go back again . they took the box out of my hand and gave me a new one . which of course is missing the top part for the mount . very very unimpressed
I bought two - on one of them, one of the light switch rubbers was already ripped in the packaging.
Using one on my FAST helmet, it looks like it'll be functionally useful for low lighting needs in dark environments, to keep from tripping over bramble in the bush while keeping the hands free for other purposes - as is my intended usage for it.
