Clifton;
Sounds like you have an early E3 which means that it has since been updated at least twice based on the Peter White web site and his beam photos. The sequence is E3, E3 brighter version and now the E3 Pro. If you compare the E3 beam shot that is highest on the Peter White beams page with the later one further down the page the increased amount of light being put out is very noticeable.
