In reply to climberchristy:
I have both the older and new versions of the Icon.
Although they claim 500 lumens on the new one, I found the light a bit underwhelming because you can't focus the beam (or at least I can't figure out how to do it) so while it will illuminate a large area, it won't do a really good job at it as it spreads the light too much and too thin.
Also, mine has a very annoying high-pitched buzzing sound which, for me, makes wearing it for more than 5 minutes unbearable, and googling around, it seems that this is a common issue with the Icon.
I've recently switched to the Ledlenser MH10 and the performance is head and shoulders above the Icon (plus, no buzzing sound!). I've paid £60 from Amazon for mine which is similar to what I've paid for the Icon too.
