Question: Can i put it in carry on bag and go out security fine? any issue?
Document: This are a work horse battery. Granted they are not as small as some of the micors on the market but they are very nicely priced. i have 8. All work well, the batteries last long and are rechargeable. I live in the country and have dogs so we do a lot of stuff where it is handy to have a flashlight. I put one in each car and one at each door. One on the nightstand and one in my EDC bag. Niice!
I guess I should start off  by saying I am a first responder and I needed a good backup torch. I have a streamlight (that is quite bulky) and that torch does the job well. I purchased the Ultrafire as a backup and keep it in my go-bag. It's pretty bright and light weight. As advertised, the light comes with multiple options when you 'click' it on. Truthfully, it's really annoying. I'd rather it have one bright option and one strobe option.
Former first responder / USAF Security Police Officer and I've had several (too many) flashlights. I was looking for a light to replace one I bought that broke and I also wanted to give my son in law a new light for his flight bag as he flies about every few days as a Capt. in the USAF. The previous lights I bought were the 240 lumen tactical type lights and they lasted about two years. ($5 from China what can you expect!).
The flashlight is bright. It arrived on time. The charger could be an issue, I had to wiggle it to get it to charge.
Flashlight did not function at all. Used the supplied rechargeable batteries (fully charged) and 2 CR123 batteries, all of which functioned fine in my Fenix PD32 UE.
I have 6 of these I use them every where I keep 1 in my car 1 in my work bag and a few in the house and one on my belt can't beat the beam for the price
its not a 100-300 light. stop pretending it is. for the price and its brightness its way worth it. bought them as gifts. carry one with me all the time. the clip on these is very convenient.
Had this for a few weeks now. Carry it every day. It seems quite durable. Certainly not as brite as advertised but as good or better than anything under $50 you will pick up retail.
well really good flash light for the price, is really bright and easy to carry in your pocket, also the battery is really good, but my flash light looks like i was use,.
Best flashlight for the money! You can't buy another Cree light of this quality for twice the price. Mine works great for my every day carry and holds long charge.
Answer: yes
