Comments about Big Blue CF600 LED Lumens Light:

I was impressed with the power of this flashlight. Far above my expectations.
I found a little heavy in the water. But it's not a big problem.
I think it could come with a protective cover to be stored.

Questions & Answers Powered by TurnTo®

Questions about this item:

Shopper  It this item blue or black?
Steve S  This light is black in color.
Shopper  I have read reviews that say you can't twist the head to focus more than about 50' deep. Have you found that true?
MICHAEL T  no, I've been down to 150ft and twist it. It's a large light at 190*59mm, so I don't like it anymore. This runs on 3*AA's. I recommend lights that run on Li-ion batteries since they can supply higher current for brighter lights. LED tech has greatly improved recently.
Shopper  Is there a spot to attach a lanyard?
MARK M  Yes. I recently purchased the CF600. There is a hole bored in the base where I have placed a moderately sized split ring. I will attach a clip on the split ring to clip to my BC. You could also attach a lanyard in this way. You could conceivably put a small lanyard cord through the bored hole, but it would have to be a very small sized line, which might break.
