My RC-N3 Q5 has the extention so I can use 2 AA's. I have 2 mounted on my handlebars and it's pretty darn brite. I have a bunch of alkalines I'm trying to use up. I got about 5 hrs out of one set and another set is still going strong. I haven't tried my nimh's yet. Supposed to get longer battery life with them. I'll post what they do.
