USB Powered Bicycle Light, LED Headlamp Waterproof 1800 Lumens 4 Modes Cycling Front Lamp Bike Headlight for Mountain Road, Kids and City Bicycle - No Internal Battery

JUST SIMPLY LOVE IT, IS BRIGHT AS THE SUN.Piece of advise don't complicate your self using the batteries for the provided batery container, by any regular USB Charging battery like the one you use for cell phones and you're good to go.Is really a great head light.

I tested this unit after it arrived. First thing that didn't seem right is that it didn't light up using a 90% charged battery. I charged the battery to 100%. Then it lit up. I let light run on highest brightness for a half hour or so and then it went out with battery at 94%. I then tried with a second battery charged to 100% , would not light. Recharged 1st battery to 100% still would not light. Returned for refund. Ordered the 2 LED variation, that one has worked OK during a few hours of testing.

Nice and bright, great for an e-bike with a USB outlet. Pretty compact (smaller then I expected), but very bright, and a strobe/blink mode. For the price this is hard to beat if you have access to USB power on your ride.

Bought this for a small Bike light. I was specifically looking for one without an internal battery and was usb powered. This was a perfect fit. Was smaller than I expected but wasn't really an issue. 4 modes low med high strobe, however the claim of 1800lms is not accurate. High is maybe 150-200 at most. Also being spot lights, good for long range but poor for side visibility. Overall I am satisfied and would probably purchase again.

There's a row of three lights on the back to let you know what power level it is on but they don't work. It just keeps one of them lit all the time. On or off, that one stupid light is on High power or low power still that one stupid light.Wouldn't buy it again

Very bright and seems to be rainproof. It has 3 brightness settings and I'd guess it's probably 400 lumens at it's brightest. It has a nice wide beam and i can easily ride in total darkness. It plugs into any usb power bank so extra batteries are cheap. A 10000mah could probably power it for a few weeks or more worth of commutes.

These are super bright and run off of a 5v power bank. I was running two of them off one super bright.

One has to wonder why it has 3 LEDs when there are brighter 1 and 2 LED heads. But, it is a very low price.I am giving it 5 stars due to the low price, but I am actually not keeping it because it is way less lumens then claimed, and I found a two-LED unit that was $9 more but much brighter and lighter weight.Witholding a star because it would be better with 1 or 2 LEDs with the same or more total output.

The excellent make-up of this gadget makes it an invaluable tool in the use of my mobility scooter

Bought the light back in April and with three levels of brightness, it has worked great so far. Just realize you need an additional USB power source, which I already had. I am very satisfied.

Es un excelente producto, muchas personas cuentan con una power bank para su telefono celular hay de varias capacidades yo tengo una de 20000 de la marca anker que es muy buena, la mayoria de las linternas de nueva generacion de mano o de bicicleta proporcionan una increible luz blanca pero lo malo de estas linternas es que usan pilas modelo 18650 de muy baja calidad por lo que la luz brillante dura apenas unas 2 a 4 horas y despues se agota y en poco tiempo de 1 a 4 meses pierde retencion la bateria por lo que deja de servir tu fantastica linterna brillante . Con esta linterna para bici tienes la oportunidad de ocupar tu power bank de tu celular y tendras horas y horas de energia dependiendo de que capacidad sea tu power bank ,por eso conviene esta linterna para bici por que ya tiene un cable usb que solo lo conectas a tu power bank y no te preocuparas por quedarte sin luz brillante , muchos alguna vez han ocupado esas linternas que tienen baterias de mala calidad y les dura poco el gusto de la luz brillante , analicen y veran que les conviene esta linterna es mi opinion

タイトル通りです。1800ルーメンに期待して購入するとガッカリする商品です。暗すぎるという程ではない（正味600ルーメン程度）ですが、そもそも1800ルーメンの光量が必要なほど暗い道を通る為に買ったのにこれでは話にならないので全く使用していません。そして暗いわりに本体がデカい。アルミ製の切り出しのような仕上げなので角が鋭利で危ない。総じて使いづらい物でした。

Brightness is direly misrepresented. I don't think it's 1800 lumens, and so does the RioRand one. But the latter is so much brighter than this light. Maybe I got a defective one? I don't know.There's a foam padding where it attaches to something, which feels very cheap and looks like it will not stand the test of time. The Riorand light has a rubber padding.But this light has a better form factor than the other light.Another plus side is since this plugs into USBs, you can use a safer portable power source than the other light.And strobe function is not so good. It's only around every 500ms (twice per second). I guess it's okay. The riorand light flashes more times in a second, maybe 4 / second.
