Product Description

Manufacturer's Description

To preserve the condition of the Lithium battery, when the Boomer isn't used for an extended period, the batteries should rest at 50% charge. To achieve this, simply charge the Boomer to 100%, hold down the button for 5 seconds. This will turn the light on and automatically shut the Boomer off when the battery reaches 50% charge.

5.0 out of 5 stars Worth the money 15 July 2011
By Gavin Owen
Amazon Verified Purchase
This light (and its twin rear light) is fantastic - blindingly bright if you look directly at it and yet it fits in the palm of your hand. The diminutive size coupled with the simple wrap-around method of attaching the light to the bike mean it takes seconds to put the light on or take it off and it can be popped into a coat pocket. USB charging is a great idea.

5.0 out of 5 stars Great urban light 7 Nov 2011
By Mr. Roger L. Baker
Colour Name:Black|Amazon Verified Purchase
This light from Knog is quite bright enough for my urban cycling, it indicates when it is charged and cna charge with the USB either with a power point or through my computer, no more suddenly finding I need a battery to get home in the evening.

4.0 out of 5 stars Great innovation for cycling
Only thing I dont like is how difficult it is to get out of the case to charge, but apart from that it is much better than battery powered lights!

4.0 out of 5 stars Amazingly small but powerful
For the size (and price), this is an amazing product. It looks great, takes little room in your bag, can be put on and taken off in seconds, and does a good job. Read more

I thought this was ace to begin with and then after recharging it for only the second time it died on me. I have now purchased a Moon light. Hopefully this won't die.

5.0 out of 5 stars Bike Light
A very good bright little light. The method of connecting the light to the bike is excellent and ought to be replicated on other lights.
