If you want to order the Brinkmann Nextsar xenon lamps, which are physically identical to the 2AA Mini Maglite lamps go here:

They cost $4.95 for a card of two, and shiping is *included* in the cost, so you really do pay only $2.50/ea., delivered.
They put out about double the light of the 2AA Mini Maglite, and it's much whiter, as well. I've put them in all of my 2AA, and 2AAA Mini Maglites. Of course, I'm not using my Mini Maglites much these days, but the Brinkmann xenon lamp is a big improvement over the 'standard' bulb found in the Mini Maglite, and I assume, it's many knock-offs.
