The Lowdown: Blackburn 2'Fer
The Blackburn 2′Fer weighs 29 grams and we measured 65 Lumens out of it. It's rechargeable, yet only costs $25 and the kicker is it has white LEDs and red LED lights built in. Thus, it can be used in the front and the back as a versatile 'to be seen' light. It's not the brightest light, but it's certainly the smallest and most versatile light we've tested to date.
The Blackburn 2'Fer is discussed in the first part of this round up video below.
