Black Diamond's ION Headlamp has a good output (80 Lumens) for such a lightweight unit and the swipe control is pretty simple to operate making it ideal for ultralight enthusiasts.
Black Diamond says: The smallest, lightest and most fully functional headlamp that runs on AAA batteries, the Ion features powerful LEDs and touch-sensitive housing for ultralight outings and emergency use.
Extremely compact and powerful, the Black Diamond Ion headlamp packs 80 lumens of power into a tiny package for just-in-case lighting and ultralight missions. The touch-control housing lets you switch from full power to dimmed, strobe or red night vision lighting at the swipe of a finger.
Black Diamond's Ion Headlamp is an ultralight headlamp with a very good light output for its size and weight, as well as a range of useful modes. Most usefully you can dim the light output to suit what you are doing and it also has a locking feature to prevent it being turned on by accident in your pack.
The key feature of the ION is that the functions are accessed by swiping your finger over the front - this is less fiddly than you might think because you slide once to turn it on, again to turn it off, and you keep your finger on it to adjust the brightness.
Using Lithium batteries the life is pretty impressive too with 8 hours on the maximum setting but 200 hours on the minimum (4 Lumens).
