Review: Nice! - I found this light on sale for a fraction of the listed price (which I could never afford), and decided to purchase it for those **very rare** occasions when I have to do a longer night ride. Since I haven't had the opportunity to use it so far, I will limit this review and some tips to what I found when I took it out of the box and tested it. First thing to do is charge the battery before first time use as done with a cellphone or any device like that. Installation and plugging together is pretty straight forward. A broad Velcro strap comes with the kit to attach the battery. When I connect the light to the battery it flashes briefly once, and the two buttons light up. Oddly enough, the instructions don't tell how to turn the light on and off and change the settings. As others already pointed out, the left button turns the light on and off. The right button changes the three brightness settings (low, medium, high); and after holding it down for a few seconds changes it to blinking mode. Once it's there, another click changes it to SOS blinking (which I find really neat!!), and the next click brings it back to steady. Pros: It's seemingly well made, small, compact, and relatively light weight. It's easy to detach, and both light and battery are small enough to fit in a fanny pack or saddle bag- definitely a plus since I wouldn't let it on the parked / unattended bike! The housing is all aluminum, which is important as the light gets warm really fast. Having one button for on/off and another for changing settings is a BIG plus! The three brightness levels cover every situation- the low setting is similar to the average battery operated head light; the medium is really nice, and the high is extremely bright- I plan to use medium and high as low and high beam on a dark road; and the low setting for well lit streets. I would be careful with the (very fast, almost strobe-like!) blinking mode, and advice against using it at high brightness- I got dizzy when I tested it, and there are people out there who are susceptible to fast blinking lights. The SOS mode however makes a really nice emergency light, and is definitely a plus. Cons (and suggestions for improvement): The (aprox 4') cord might be a tad short for some users, and having a pouch for the battery would be nice. Also an in-line off / on switch so the light doesn't have to be unplugged every time between uses to avoid draining the battery. A real disappointment for me was the head mount. I was planning on using this light when I have to work in dark, confined spaces (which I do very often), but since I cannot point it up- or forward- only down at a (at least for me) unpractical angle, I will use it on the bike only... for which it is primarily intended. Overall, this seems to be a really nice light!
Review: Extremely bright, seems very well made, and lights up a wide area very well. Out performed my needs. - This light is so bright it’s unbelievable. I have a very nice stream light flashlight and this is just as bright if not brighter. For the money it is really a great buy as most lights this bright are much more expensive. I was worried about the dispersal pattern, and while it is like a very large, very bright circle with a slight halo around it, having this mounted to my handlebars made the entire trail in front of me Light up bright as day all in the central bright area and the halo was just a little lagniappe. I am riding on a windy trail on a levee along the Mississippi River so I really did my research and comparisons before I made the purchase as I didn’t want to fall in or become gator bait. This light is like a headlight and exceeded my expectations. It also has a very white color to it on the brightest setting which was useful. I passed a snake on the trail and not only could I see it from a distance but I could also make out the colors as if it were daytime. This is the only bike light I’ve used in the past 15 years but in the pitch black, surrounded by river and farm fields, this thing was an absolute wonder and I can’t imagine needing a brighter light or a wider beam for any normal activity. The mount is going to take a little tinkering though, and as I can’t easily mount it to the center of my handle bars, and it doesn’t pivot or swivel, and my ocd cannot have an off center light guiding me..I will have to get creative with how I am going to mount this thing in a way that it will be centered and not move around when I hit bumpy trail (I was, however, riding a road bike on a gravel road so I might as well have had wooden tires..my teeth were all but chattering from the vibrations so I’m not surprised the light was shifting a bit. When I got to paved trail it was completely steady. All in all this is a light firstly and they definitely focused mostly on that, which I am not upset about. It seems sturdy and the battery mount is excellent. The headlamp accessory was a nice touch too though I haven’t used it. I also noticed this light lit up reflective road signs that it was not even pointing at from about 75-100 yards. It’s a lot of light, and I do not regret this purchase one bit.

## Questions & Answers

**Q: I would like a second battery pack to attach when the first one is completed. I ride on remote trails for extended periods at night. Where may I buy?**
A: Don't forget you can also buy lithium cells and battery packs that come with something other than 18650 cells. For example, a pair of decent quality 21700 or 26650 lithium-ion cells in 2S1P configuration can provide a LOT more Ah than a pair (2S1P)...or even a quad (2S2P) of decent quality 18650 cells. A 21700 cell of the same chemistry can provide about 50% MORE POWER for ALMOST the same physical cell outside dimensions (18650 v 21700: 18 to 21 = just 3mm wider diameter, and 65 to 70 = just 5mm longer (the last 0 in the number means it's a cylinder)). In practical terms it means by using 21700's instead of 18650's, you can get either longer run-times per charge or the cell's lifespans can be increased due to lower stress on them in fewer discharge/recharge cycles. I recently purchased a pair of Samsung 21700 5,000mAh cells (REAL mAh value...not a fake marketing claim) for $26, already packaged as 2S1P (8.4V) with a battery protection circuit. Two of those packs in a 2S2P configuration would fit in one of these FLEXIBLE fabric battery bags with no problem, providing a REAL 10,000mAh battery pack. 
(NOTE: way too many companies make fake claims about the mAh capacity of the 18650 lithium-ion cells they sell. Any mAh claim over 3200mAh for a 1S1P configuration 18650 cell is in general VERY suspicious, and is certainly not going to be cheap. Similarly any 2S2P (4*18650) configuration 18650 8.4V pack claiming more than 6400mAh is just as suspicious). I recommend reading batteryuniversity website.

**Q: I have just purchased this product and have two questions. 1) Is this 4000 Lumens? 2) How long does it take to full charge the battery?**
A: I don't think it's 4000 lumens but it is plenty bright for fast night riding on a bicycle. It took 5 hours to fully charge for the first time.

**Q: This light has an uncanny resemblance (both in looks and price) to the "OXY LED BL-15" light, is the performance the same?**
A: Not sure about the OXY comparison. I've had mine about three months.  Definitely lives up to brightness claims.  On high setting it gets around 2 hours.  It has a flashing mode and three brightness settings.  The battery is a little awkward.  I put in in an empty water bottle and wrap the cord around top tube.  I just use it for commuting, so not sure where I'd put the battery if I needed both water bottles. The rubber bands which attach to handlebars are a weak point as I have already broken one and worry about them snapping as I ride.  Overall satisfied with the product.

**Q: Battery pack - it holds 4 18650 batteries? Are 4 supplied? Can it work with just 1 or 2 batteries active?**
A: Have not tried only with the 4

Its on the heavy side and the battery pack is large but its really bright and can illuminate for a long time. Have yet to do a night ride and run out of battery though we only used it less than 2 hours.
