Headlamp,Cobiz Brightest High 6000 Lumen LED Work Headlight,18650 USB Rechargeable Waterproof Flashlight with Zoomable Work Light,Head Lights for Camping,Hiking, Outdoors

Very - Very bright lights; GREAT for running! You can see almost a full mile ahead of you plus all around you. You can adjust the scope of the light as well. Perfect for running trails/road in the dark.When I first purchased this item and went running, the headlamp became extremely uncomfortable. I initially thought that I was wearing it too tight so I loosened it but then it started jiggling very badly. Then the top strap broke after a few miles. Seems very poorly put together. I was so disappointed because the lamps put out so much light and I run early in the morning when it's dark. I posted a negative review and the company contacted me immediately. Seems like I received a defective product. The headlamp was missing the padding on the light housing that sits on your head and the straps were defective. They immediately sent me a replacement at no additional cost. Already used the replacement and it rocks! Great head lamp and great customer service. You cannot beat the price for this.

 This 3 LED headlamp comes with 2x 3.7v Lion batteries, a charging plug pack, and a case to store everything in.The overall construction is more than acceptable, with aluminum LED housings, and heavy duty components. The focus mechanism on the main lamp works amazingly well, and ratchets easily.The LED function is fairly standard, operating from a single button to select modes: main on, aux on, all on, strobe, off. A dim red light on the battery pack lights up when the lamp is functioning.All parts of the lamp that touch your head are padded, which is nice. The lamp is on the heavy side, so the creature comforts are well appreciated.

I have used my headlamp for the past few weeks and wanted to make sure I gave it a fair review without just jumping to conclusions.First Impressions:The Bad...-Right out of the box I was starting to wonder how anyone who received this product gave it anything above a one star. It feels terribly cheap (It is!) and the build quality is really low. It also has a very strange odor when you pull it out of it's case. Just expect to feel a lot of plastic when you first touch the parts you may have expected to be aluminum.-I think that it's biggest shortcoming is definitely the battery housing. The cover that protects the 18650s and wiring is a soft piece of rubber that is merely held on by a little friction. No clasps or straps to ensure a tight water-resistant seal. I highly doubt that it would be able to endure a heavy rain or just prolonged exposure to a wet environment. I would definitely prefer a plastic cover with a rubber gasket and some form of fastening to keep pressure on the seal.-The lighting system, while only being housed in plastic is bright... just not anywhere as bright as they advertise. I would have to guess (comparing to some of my other flashlights) that it is closer to 1250-1500 lumens with all 3 lit. It is not noticeably brighter than my Thru-nite that is advertised as 1250 lumens.The Good!-The weight of this headlamp is great! While this might be due to the lower quality build materials, it does allow it to be forgettable while it is on your head for extended periods of time.-The angle adjustment is not loose and does not hop around from movement over time. Often headlamps with a large set of lamps on the front can be annoying from having to readjust it numerous times during a hike, but this one does well.-The light focusing system works well! It is nice being able to adjust the central lamp from a wide angle down to a focal point that turns out to be just a square projection of the led chip.-From what I could tell the battery life is sufficient. I did not run out of juice and did not notice any decrease in the light's brightness for a three hour sojourn in the dark. I was however flipping through the light intensities since I rarely use the brightest settings unless I am setting up camp or attempting to see across a field.-The charging system is pretty decent. I like that the charger has a notification light to let you know when it is done charging. Just a convenient trait to have if you must charge the 18650s inside the headlamp.-The case is actually pretty solid and is convenient so that you do not lose the charger when using the headlamp. Just don't lose that case now...OVERALL:So overall I would say that this light is alright. It is really cheap and you can tell by handling it. However that is what you should expect when paying less than 30 dollars for a headlamp with this many features. While the components are definitely a bit cheaper, they actually do a good job! (With exception to that battery cover) The battery cover is the only piece that kept this from being 5 stars and that leads me into my final thought. While this headlamp can do a lot for a low price, it is the specs that it advertises and boldly puts out there that is far from accurate. It claims that it is "Waterproof" without giving any form of ip rating, which should speak for itself alone. Also It claims to be 6000 lumens which is just an exaggeration. These parts are major selling points in headlamps and they know that because they have been quite fine with exaggerating this flashlight's capabilities. If that is fine by you, then go for it. I think it is a fine flashlight for the price and will keep using it until it stops working.Update (June 26, 2018): I was contacted by the seller recently and have been shipped a secondary unit to evaluate and see if the overall build quality and light output was just from a faulty unit. I will update based on the findings and comparing the two units fully charged. I did up my rating from a 3 star to a 4 star in the meantime to account for customer service. Also I have yet to run into any additional qualms when I expected by now it to stop working.

 I first want to point out that this has a pretty universal fit since I can stretch it wide eoniug to fit on a hard hat but also make it small enough that my 7 year old can wear it confortable without it beeing too loose.This has three lights that work in different combinations which also deternime the run time. If all three lights are on it will last 1- 3 hours whereas if you use it in the two side light mode it will last 3-5 hours. The charginf time is 7-8 hours for a full charge so I would suggest getting some extra batteries for backup for long trips.Some of the features I love on this is the adjustable headband with one that goes over the top of the head which really helps to stabilize the lights and set a good fit without giving yourself a headache from over tightening.Another feature that I love is what I call the follow light. On the back of the battery pack which sits on the back of your head is a red light that is lit when the light is on in the front. This makes it much easier for people behind you to follow in the dark and not have to try to constantly adjust their eye while trying to just follow you headlight. This feature alone put it above all other headlamps I have used.This head lamp also comes with a two prong power cord for charging but like I said I would get more batteries. Please realize that these are not AA batteries but a size 18650 li-ion which can be found on Amazon for fairly cheap.This has been a great addition to my go-bag for emergency response and is also very helpful in dong car repairs and those dark honey-do’s. This lamp makes me a lot more useful being able to use both hands.I did notice that I may need to put some sort of clips on my helmet to keep the band from slipping off but hat is not a design flaw at all…just a functional one that I need to figure out.Finally this does come with a convenient case to store it in so that it doesn’t get banged up while be transported or stored.Overall I give this amazon light a 5 out of 5 stars.
