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.

Full Review: Blackburn 2′Fer

This was one of the pleasant surprises of the shootout. Here is a small light with a clip that claims 60 Lumens for a 20 gram light with a $25 price. We took it to the lab and it indeed measured at 65 Lumens which is even higher than claimed.

The secret weapon is that it has red LEDs positioned opposite its diagonal white LEDs. Thus, at the press of the switch the white headlight can be used as a red tail light.

Integrating Sphere Measured Lumens

This light measured 65 Lumens in an integrating sphere. Claimed Lumens by the manufacturer is 60 Lumens. Compare all Lumen Tests here »

The numbers are staggering. Two lights in one for $25? That is a good deal indeed. The brightness of 65 Lumens is legitimate ‘to be seen’ output out of this 20 gram light.

The light comes with a built in clip that can be attached to a backpack, saddlebag or article of clothing. But if one wants to attach it to the handlebars or seatpost, the clip can attach to an included strap mount. This brings the system weight to 29 grams as the rubber strap is able to wrap around any tube on the bike.

Incredibly light at 20 grams.

Are two lights better than one? Is there any utility to having both white and red LEDs on the light given that they can’t be both on at the same time? The answer is yes. What the light gains is versatility. Normal use is for one light to be a headlight and the other to be a tail light. But both can be headlights if one needs to see better. Or both can be tail lights, one on the bike and one on the helmet for example. Or the lights can be shared between bikes.
