Question: how many lumens
Document: i LOVE this light i gave it 3 stars instead of 5 because it is advertised incorrectly. it is in no way shape or form 1600 lumens. MAYBE 900
Would like an honest Lumen number from Amazon on this flashlight, which is otherwise not bad, sturdy. We will see how it lasts... Compared to my othe flashlights it's really more like 200-300 lumens...
i have never owned an led flashlight before. I have many mag light flashlights. 3 three D cell one 6 cell and this little light is by for brighter than all those lights could ever be. this is great for work on third shift and walking dog at night. I can see for miles
If you are a pro photographer and are on a shoot and end up at a location that does not allow flash, this light could be your saving grace. It has a good color spectrum and with the included UltraFire BRC 18650 4000mAh batteries you have plenty of time. This high tech flashlight has many uses, but for me the photography uses are exactly what I'm looking for.
I have other smaller Cree flashlights (250 lumens) and they work very well compared to more expensive tactical lights that I have purchased with lower lumen values. The aluminum body machining is very good and the zoom works easily. The brightness of the light is amazing. I tested like in some videos I have seen on youtube and it really lights up the house across the street.In a dark room in the house, it fills almost the entire room to easily see everything in the available light.
the light worked great and was super blind-yo-ass bright for a full three days before the spring that contacts the negative side of the battery crumbled like a month old cookie.
ive read alot of bad reviews on this product but i must say even tho the light prob isnt 1600 lm its by far one of the best lights out there, very happi with it and the only reason i gave it 4 stars is because it doesnt have memory. other than that great light
excelente producto
This light works, it's bright, and it's a decent looking tool. It's NOT even close in it's lumen rating, but if you were expecting honesty in that category, in this price range, you're nuts. For what it costs, it's a great light.
This is one of the best lights I've ever used. I am head of security and have need of a light during our Hawaiian nights. It has the biggest/brightest coverage and has a cool looking spot light option that shines a square light. It has another option of SOS and flashing just by clicking the on/off button twice.I purchased two others for my crew from another company and found out they are NOT the same.
Answer: yes
