I’d suggest a Specialized Flux 1250 as an option. You’ll get a styled, dual-lens, underbar unit that runs parallel to the handlebar (i.e it’s wider than longer), so better looking and more discreet, and at 1250 lumens, you’re not sacrificing but 50 lumens compared to the Ion Pro. The Fluz has a bar mount, but you can also get a GoPro mount if you want to mount it in a different way; you could get a slim aluminum mount to place it close and directly in front of the bar if you have the space, for example.

Personally, I love the styling of the Knog Blinder Road 600, but it’s a step down, in terms of max lumens, from the Ion Pro.
