That's a very interesting lantern. I've been trying to decide between a Cree warm flavolight and a Coleman XPS. This lantern might be more interesting for the longer run time. How does the light output compare to a flavolight? Has anyone compared these directly?
Also, like another poster I bought the diffuser for the LD20. It does work great, although since most of my intended application would be inside the house I am thinking that simply bouncing the flashlight output off the ceiling might meet my needs and allow me to take advantage of the better efficiency that the Fenix LD20 offers...still, this is a tempting lantern.
