I also have considered leaving the healamp at home, but I still carry it.

The Petzl e+Lite is only 1.6 oz. including the worthless case. I was very surprised to find that the case is NOT waterproof. Not something you want to discover AFTER you swam your pack.

I use the coin LED that I keep on a lanyard around my neck to answer the call of nature. I never plan to set up in the dark. I never plan to hike at night. I have used the headlamp once in eight nights so far this year. Borderline useful, but I still carry it.
