SecurityIng 700 LM Bike Light for Night Cycling, USB Powered

I have a motor from eBikeling and the LCD display has a USB outlet for power. I have longed for the day when I can stop dealing with recharging my lights on my bike nearly every day and that day is here. It is nearly as bright as the blindingly bright headlight it is replacing. Update after 5 months. Based on these later reviews, it seems that there may be some quality control issues at the plant, but mine is still going strong despite being used about 50 times 10 miles each time on the pothole ridden streets of Chicago. Guess I got a good one. I am still very happy I found it and purchased it. After biking to work for 30 years now, this has been one of my most appreciated purchases. Then again, I said the same when they first started making LED headlights, which drastically prolonged battery life. I went from having to recharge my headlight every day to once a week to never needing to worry about it at all, since I never ride my bike without it's battery fully recharged before I leave .

I purchased a E-trike and it came with a stock low powered bike lamp. What made matters worse, it is fixed to the front of the trike and not the forks. So I can't see anything when turning. I purchased two of these USB powered lights and mounted them on opposite sides of the fork. (See Photos) It not only provides more light, I can now see in the turns. I have provided before and after pictures of the stock light compared to the two USB Powered lights I installed. I also purchased a Solar Power Bank rated 38800mAh to power the two lights. So far everything is working great!

Great light. Extremely bright. Works great. If the cord was a bit longer it would be a 5 star review. It wouldn't hurt if it had more settings but hey, for a lot more money you can have two more settings. So for cost, it's a great buy.

Better if I had a built-in cord, otherwise nice and bright

I don’t think it’s as bright as it claims, but for the price you get wayyyy more than what you pay so 10/10. It seemed closer to my 900 lumen light, but I like the fact that I’m not limited as to where I can mount it, and I can plug it in to any battery pack. Plus the light lasted wayyyyyyyyy longer than expected so that too is a plus. 5 stars for me, as I purchased it with considerably lower expectations.

Great lights! I bought a cree x3 bike light about 4 years ago and it’s one of my favorite and brightest lights I own. I bought this cree x2 light because i wanted one with only two leds to reduce the power usage and also I wanted the usb plug in power option. I just plug this light into my 6500mah battery pack and I’ve used it on my first ride and it was on low for approx 3 hrs and high for approx 20 min and it only drained the battery down 2 of the 5 power bars. These are nearly as bright as headlamps on a car. My buddy always makes jokes saying how he should just buy one of these for his motorcycle because there brighter than his head lights. Lol. Good buy for the price! I recommend buying one of these before you waste your money on another bike light that’s about 150$ that would come anywhere close to the light output this thing puts off.

plugged in to usb outlet on e-bike battery...nothing, just brief flash, works fine from desktop usb...just don't ride desktop to work!!

This Light Plus a rechargeable usb battery pack is one of the most inexpensive and robust setups I have ever used on my touring bike. Very bright LED light that illuminates all hazards in the road and seems to last forever on the lowest brightness setting. The only thing I would note is that the light itself is a bit larger than the photos make it seem.

Exactly what I needed for my Bike-packing system. One central battery bank to run multiple lights instead of each having their own battery that requires recharge independently, wasting time. These are super bright, well built and efficient. They do get very warm, but only on maximum power, and they are clearly designed that way to protect the circuits. Handy to warm your hands on briefly, not hot enough to burn. I tested a pair of these running simultaneously on full beam with a 26800mah battery (almost full) and they lasted 6hrs, pretty impressive. Re-test with one on flashing and the other on normal (Set up I intend to use) lasted 16hrs!

たくさんの自転車ライトを買って試してきたが、これがいちばんいいかも。 モバイルバッテリーとつないで使うもので、 ライトにはバッテリーが入ってない。このタイプがなかなか無い（おそらく２種類）から困る。 軽いし、長持ちするし、何より電池残量が数字でわかるし、 モバイルバッテリーはスマホにも使える。 そこまで明るくはないし、モバイルバッテリーは雨にも要注意。

As advertised! Very bright light!

以前にも非USBタイプのライトを使用していましたが、バッテリを紛失して使えなくなり、本品を購入しました 機能は変わらず、USBバッテリが使えるようになって使用範囲が広がりました

Got a couple of these for different mountain bikes, like to fit one to my handlebars and one to my helmet (with seperately purchased adaptor) works pretty well and have one on my road bike that adds likelihood of cars seeing me on my commute when in flashing mode (although do worry all that flashing will lead to me having an epileptic fit one day!)
