Each to their own <img src="/forums/images/graemlins/wink.gif" alt="" /> I found the lantern topper to be cute and useful - and it adds barely any weight to a pack. I carry Nalgenes in winter (being heavy duty/capable of being upside down without leaking). If you are already carrying a bottle, it barely adds weight to a light setup. And price wise it wasn't too bad either. Guyot is a pretty cool company overall - they make neat items.

For me, sometimes it is nice to have a diffused light where there isn't blinding headlamps - something I myself hate when I want light, but not blinding light.
