Ya know, I'd be interested in what Jason suggested - an unbiased side-by-side comparison. I think it should be done by someone on this forum using real life practical tests. How long can you read by its light? How well and how long could you hike by its light? Weight, comfort, adaptability, battery type, battery compartment ease, performance in various temperature ranges, etc. And all done in a consistent, coherent language. Honestly, who knows best how these lights should perform? You guys, some of whom have 30 years experience or more on the trail, or lab techs?
