Newbie - Help Quick!!

Long time lurker, but I've found something that I can't search for and I need ideas.

I've bought more than a handful of lights after reading posts on here. My SAR team is leaving for someplace down South in 24 hours in the hurricane aftermath. I've got all of my lights together, with a great big thanks to Greg & the crew @ Brightguy. He sent me an Epieon LED bulb for a 2-cell, and when I tried it out it seemed really dim. I did some looking and it turns out that it's really a 4.5v for a three cell. I've been to Wally World & Home Depot and couldn't even find a Maglite to hold it. What would be the best host for the Epieon?? It needs to be something relatively easy to find, since I've got to leave so soon. TIA!

Try Target for 3D Mags or you might be able to find a 3D Rayovac somewhere.

I got a USA made Rayovac 3D at ACE hardware...

I got a Thailand made Rayovac 3D at Lowes...

FIND A USA Rayovac!!!

I have used 3 cell (4.5V) Epieon on one of these, using 4AA NiMH (4.8V) works fine and very bright. I like Epieon better than EverLED because you can overdrive it and focuses narrower in M*glite.
