Night Provision BX550 Rechargeable USB Bike Light

On the brightest setting the light will produce 550 Lumens running about three hours. Of course with any battery operated device, the lower the brightness the longer the life of the charge of the battery. The three setting of this light consist of 550 Lumens, mid at 250 Lumens and the lowest setting shines the light at 50 Lumens. At the lowest setting the light will last about ten hours before having to be recharged. There is also a strobe mode, which flashes at the brightness of 250 Lumens. You can simply and easily check the battery power by holding the button down for three seconds after the light has been turned off. The light will then flash from one to ten times, with ten times meaning the battery is fully charged. I have used the light for commuting and it is plenty bright on street light lit roads. The light is only able to be attached on your handlebars and can’t attach to a helmet. The mount it comes with can stay on the bike and the light  can simply slide out. The light is very secure and stable in the handlebar mount. The mount ratchets to tighten when putting on the handlebar. The light comes with the necessary USB charging cable. This is a great light for any cyclist or mountain bike rider. Keep in mind this light is only able to be attached to handlebars and not the option of both handlebars or helmet. The ease of being able to charge it in a computer or wall USB charger is perfect for commuters who may need to charge it while at work. 

The lights battery can be checked by holding the button in for three seconds.  The light will then blink anywhere from one to ten times.  Each blink is ten percent of a charge.  So if the light blinks six times, you have a battery that is at 60 percent. 

I am a fan of using any light on the strobe mode, like this one that on that mode shines at 250 Lumens, during the day when commuting and riding with traffic. 

 Note: I was offered the light at at discount for supplying a review.
