one of the best lights I've hadReview by Taylor ➣ Perennial Cycle Sales/Merchandising Specialist
:
I have been running this light on my winter rig for a few months now and I have nothing bad to say about it. I love that I always have lights on bike and never run out of batteries. The spread of light i get from the IQ-X is perfect. It's bright without blinding people, keeps me visible from the side and stays on when I stop at intersections. It's not complicated and does exactly what I want it to do. I'm scheming on how to put this set up on all my bikes. (Posted on 1/25/2018)
such a wide, bright beam!Review by Karl
:
I installed this light on my Brompton, and liked it so much I bought another one for my cargo bike! It's currently the brightest dynamo-powered light available, and the beam pattern is very wide and well-shaped. I used the provided multi-joint bracket on my Big Dummy, but it was easy to substitute the Brompton wire-form headlight bracket to fit it perfectly under the front luggage on the Brompton. The mounting band can be inverted to suspend the light beneath a front rack without affecting the beam pattern or rain-proof construction.

Wiring was simple; the power wire is permanently attached to the light and the taillight wire is a short pigtail terminated with 2.8mm male spade connectors. This light works with almost any dynamo taillight; I paired it with a B&M Toplight Line Small on my Big Dummy and a fender-mounted B&M Secula on my Brompton.

If you're looking for a powerful headlight without lots of confusing modes or add-ons, this is the light for you!
