CYANSKY HS3R Headlamp Rechargeable,with 1100 Lumens High Brightness,L-Shaped Flashlight with Red Light,Lightweigh,for Outdoor Sports, Industrial Work, Repair, and Camping (HS3R)

This isnt the brightest flashlight at the price point. Its not the longest lasting. It definitely aint cheap. I wouldnt consider this a bang for your buck if you just want a headlamp and dont sweat the cheap plastics or disposable batteries. If those are the only things of importance to you, I would forgive you for passing on it. What it does exceptionally well though, is gather together many of the best conveniences in the flashlight market, both old and new, in a market overflowing with geriatric products that haven't been upgraded in years, some cases even decades, producing a very durable, yet uniquely convenient and TINY flashlight. One that also fits very securely on a steel buckle and adjustable strap to make for a criminally underexposed product. Its not Bang for buck, its POWER (and modern conveniences!) per POUND! Quick-ish pro's and cons +++ I am absolutely biased towards products that are compact and effortless to casually carry about. You can easily stuff the entire headlamp, strap, light, and buckle, into just about any type of casual pocket and have room for more, to say nothing of if you simply pull the entirely self contained light off the buckle, now retaining all the headlamps power and functionality in a package similar in size to your pair of wireless earbuds. ++No top headstrap or bulky battery pack on the back of the headlamp. The flashlight is nowhere near heavy enough to warrant or even benefit from a top strap, something other similarly lightweight headlamps should realize. An adequately tightened strap will stay on securely without squeezing your head, and without the top strap, you don't even need to stuff it in a pocket, as now you can just wear it around your neck when not in use. Very convenient like this. ++ Modern USB C power input with an attached sealing plug, alongside internal o-rings give this beauty the prestigious IPX8 rating for waterproofing (I have yet to test mine in water, but I don't doubt it). ++A standardized 700mAh rechargeable 16340 battery Inside- I bet you could buy replacements and quickly swap them in just fine, but i haven't personally tested this (because i have no reason to, the thing lasts so long and charges so dang quickly). The included battery even has a micro usb port built into it in case you cant find a USB C cable. ++Wide range of vertical angle adjustment. 180 frickin degrees. And itll stay exactly the angle you set it at no matter how you shake or abuse it. A bit hard of turning as a consequence, but ill take that anyday over the angle slipping down if you look in a direction too hard. It truly is 180 degrees too; you can point it straight down to illumate your nose to help practice going crosseyed, or straight up to help deter tall people from being aggressively tall near you. Or you could be practical and lock it at literally any angle between those two. + Supports charging while illuminated, while also preventing users from inadvertently overheating it by restricting the brightest settings while charging. Admittedly not many use cases for a battery headlamp running while plugged in, but the time they put into making it not only work, but work *safely* is commendable. + 8 different light modes (not counting 'off'), ranging from a 'rather bright night light', to 'Today i will emulate being THAT person with the LED headlights that never turns off their high beams- but without the car', alongside a red and flashing red mode, all achievable with one nice, clicky button. You can also check its battery level with that same button, to see how many more days of use you have when you pick it up. +Brightness memory for both 'modes'. Another classic premium flashlight feature, remembering what the brightness was when you last used it. Will remember low-med-hi brightness (if you turned it off on turbo, itll step back down to high, one click away from turbo), as well as if you were in eco white, red or flashing red last. +Good magnet on the butt of the flashlight for mounting to metal surfaces. Again rather edge case-y when you can already strap the light to your head, but its a staple in more premium flashlights = It has a red blinking mode, but doesn't have a white blinking/low with blinking mode. This isn't a purpose built cycling light, not to mention it already is doing so much with just a single button, so its excusable, but as someone using this for the purpose of cycling, kinda wish it did have one to make me better visible to drivers. =Can be a bit unwieldy to finagle with while biking and wearing gloves, most notable difficulty is adjusting the vertical angle of the lamp, definitely only do that while stopped unless you are very confident at biking one handed for several seconds. Theres no way to fix this without losing its impeccable ability to lock at any minute angle, so its a chosen tradeoff. = The controls are a bit unwieldy, seeing as theres only one button and 4 different functions assigned to it. Again, this is a deliberate tradeoff. The alternatives are making it bigger to fit more buttons... or just removing functionality, both detract from the beautiful balance it currently has. - The stainless steel backing buckle, durable as all heck it is, does not play well with being worn around the neck from an (extremely nitpicky) comfort perspective. I have to be careful when pulling the lamp down past my brow, as i've more than once done it a bit too fast and gotten a hunk of exposed steel smacking the bridge of my nose, as well as feeling the cold metal on your skin if you try to wear it under your shirt. All i can really suggest to fix this is trimming on the width of the buckle so it doesnt extend past the strap anymore... but i have no idea the ramifications of the durability that would have. -Doesnt have enough genuine drawbacks for me to make this not seem biased

Small and versatile head lamp.

Its like having the brightness of a car headlight on your forehead. Speaking of cars, this thing has a magnet on the base so you can stick it under the hood or under the dash for all those repairs. Or just leave it on your head. Four levels of brightness low, medium, bright and Oh My Gosh. Lol. A long press switches to the other mode with flashing red, continuous red and the fifth level of white which is very low white eco mode that will last for about 60 hours. Another long press switches back to white light mode. It takes a few tries to learn how long to hold the button down for switching on, changing level, changing mode and switching off. Charging with supplied USB-A to USB-C cord the button displays as red light blinking, then red, then green blinking and finally green when completely charged. Those same switch colors tell you the level of battery charge for a second when the light is first turned on. Nice feature to see if it needs charging. The battery is inside and accessible by unscrewing the end cap. It could be charged separately by micro usb right in the side of the battery, maybe if you had a spare battery? They have provided two replacement orings for the end cap in a little bag. When wearing it I keep the external USB-C charging port on the bottom, all you have to do is keep the headband writing right side up when wearing and the usb port will be on the bottom. The port has a cover to keep water and debris out but I wouldn’t want to keep in on the top in case “I Forgot” to close it correctly. There is a lanyard supplied but it really is too difficult to take off each time for headlamp and put back on for hand held flashlight. Works great on a thumb drive though. The headband is very wide and I find it quite comfortable for long working periods. I work on the water so this thing has been staying in my day bag for a couple of months. Loving it. There is just no substitute for massive illumination and this sure has it. I know you other backpackers want the weight so here it is, 3.17oz, just the light and headband with no usb cable. Worked out nice for a multi day backpacking trip. FYI it sticks to the fuel can so you can have a stable base for the light, maybe not while cooking. Enjoy.
