Digging this old thread up for a quick PSA.
BD has released a new 2016 version of the Ion. I first saw the Ion mentioned above with the touch controls in a brick and mortar last year. I really liked the headlamp but the touch controls drove me mad just futzing with it in the store. I had to pass on it. Turned out it was probably the number one complaint.
I came across the new release on BD’s web sight and I have to at least give BD cudos for actually paying attention to customer complaints and revamping it . I picked a couple of these up for the wife to try it out on a few short trips to see if it will make it into my bag on a regular basis.
The improvements start with a bump to 100 lumens and a water proof rating. It also now has a single top switch for all functions. The lamp functions on a progressive number of switch clicks. First click gives a nice general lighting beam. Click again and hold and you get an infinite adjust with the lamp brightness from hi to lo until letting off the switch. Additional functions give you the same in a very usable (IMO) red lamp mode and if your thing is a strobe, it has one too. Also has a lock mode for keeping safe the batteries while in the pack. Actual weight is 54g with supplies headband, which could be replaced with something lighter. It still take 2 AAA bats. and weight above includes them.
For those that may have the new BD spot its function switch will be very familiar. It is much like a little brother/sister to that lamp.
