Volcan output with non-LiIon batteries

I've been trying out my new single AA Volcan with a variety of different battery chemistries. Thus far I've run it on alkalines, lithium primaries and Eneloops. The max output with these 1.2 - 1.5 volt options has been less than impressive. To put it in perspective, the Volcan's output on high is noticeably less bright than my 2004 or 2005 vintage Amilite Neo. I forget the exact emitter in the Neo, but I expect it's putting out between 40 and 70 emitter lumens.

Is this a normal level of performance for the Volcan? I realize it's optimized for performance with LiIon rechargeables, but I was expecting a little more with primaries.

You could use 14505 lithium primaries. They are 3 volt batteries from Battery Junction. I use them in my El Caps and work great.

Thanks for the tip, jssp. I'll keep those in mind.

My fondness for Eneloops, though, still leaves me wondering what other Volcan owners are experiencing in terms of max brightness using the 1.2 to 1.5 volt battery options.

Mine u would say is putting out about 80-100 OTF lumens. It si brighter than my Malkoff M61 LL.
