I have a Brinkman 2 x AAA which is similar to a penlight but it has a wider, adjustable head like this: http://www.brinkmann.net/products/flashlights_and_spotlights/flashlights/details.aspx?item=800-2001-0
The incan bulb is a 2 pin version. The reflector and head are different than the mini mag of similar size. Not sure how the switch portion comes apart.
Would like to know if there is a simple drop-in that fits for this flashlight . . I just want to reduce battery use, don't care if this light produces a lot more light but I'd like it to be at least similar output.
