I have had the original version of this light for patrol use for probably 6-7 years without issue, it is worn to the point that the anodizing has faded to brown or is completely gone. The only reason I have to purchase a new light is due to a power surge at my home frying the original charger.
I have had 2 of these flashlights and both of them have been a disappointment. The first one lasted about a month and then the tailcap went bad and had to send it back. The one that I got to replace it which I have now had for about 4 months is now useless due to the charger cord breaking in two just from sitting in a back pack that I take it to and from work in. I cant find a place to buy a replacement but I don't think that would have been an issue because on top of that the rechargeable battery that is specific to the light is also to the point where it only holds about 2 days worth of a charge, that or the bulb is bad I really cant tell which. Point of the story is, buy a light from companies that make lights ie. Streamlight, Surefire ect.. 5.11 is the best there is when it comes to tactical apparel but some of their other items just cant compete with companies that build similar items exclusively.
love this flashlight. it is very bright and holds a charge a good while
