Super Bright LED Bike Light,USB Rechargeable Bicycle Headlight-5 Modes,Waterproof Bike Headlight,MTB Off-Road Cycling Commuting

This light really brightens the path with a super wide low beam with one push of the power button. A second push uses a single bright high beam, blinding everyone in front of you. A third push turns both low and high beams at once, illuminating everything in front of you. A fourth push blinks low and high beams. Definitely lights my path during my 5:00 am commute to work when it’s pitch black outside. Mounting it to my already full cockpit was challenging until I found a camera mount the fits under my quad lock cell phone holder. Battery life is good for 2-3 hours on low beam (I haven’t pushed it beyond that yet), but I have my old night rider 600 as a backup (it blinds everyone in front of me, so I bought this one with a road-friendly beam). I’m very happy with this purchase!

The X-Small (900 lumens), Small (1200 Lumens), and the Medium (1400 Lumens) all have different surface heat. The medium barely gets hot to the touch, it gets slightly warm. The Small gets VERY hot to the touch after 15 minutes. The X-Small also gets hot but not as much as the Small. Why does heat matter? Heat degrades battery life, it's a simple concept.Light output across these 3 are actually pretty similar. There isn't too big of a difference between the X-Small and the Small. Between the X-Small and the Medium, there is somewhat of a difference, although not as large as I thought it would be. All light up a similar amount of visual space going from left to right. Don't assume because the Medium is 2" wider, that it will light up larger left to right space.What's confusing is that across the 3 models, the manuals state opposite things about battery life, which leads me to believe they only did an approximate guess. The high beam on one model, per manuals, either last shorter or longer than their low beam settings. For example, the Small is rated: Low Beam, 700 Lumens, 3.5 hours. High beam, 750 lumens, 4 hours. How does putting out more light give you more battery life?Regardless, they put out high amounts of light. I'm using the Small, while it's the hottest of the bunch, is is still a bigger battery than the X-Small. Plus, the Medium interferes with my cabling in the front.

this was a very worth it purchase it came in fast and quick. The light is very bright! it has different modes that are shown in the video i put. it’s very easy to mount no issues with it mounting on my bike it comes with all the screws and things you need. it’s so bright i ordered the x-small and it’s still extremely bright so i can’t imagine how bright the large one would be. very good quality so i give it a 5 star

This item met and overpassed my expectations

I bought the XSmall version because I love the look and how it mounts to the handlebars. I do night rides in my city where we do about twenty miles. First trial run on the lowest steady setting, this light stopped working in the first hour of riding. Leaving me stranded without a headlight to get home. Thinking it was user error, I made sure it was fully charged before my next ride during the day. Less than two hours of riding in blinking mode and the battery was dead before I got home. This model is not a serious light in any way. Bright? Yes. But don’t plan to use it for more than twenty minutes at a time. Disappointed. I would have returned it but I missed my window. Lesson learned for me.
