If I may add my 2 cents worth, the MiniMag with the Brinkman Nextstar 2AA bulb is not only brighter but also much whiter. I put one of these together with an Acrylite lens and it was quite an improvement over the stock MiniMag.
Maybe I should be clear about this. I used a MiniMag, Acrylite Lens, Brinkman Nextstar 2AA bulb, L91 Lithium AA batteries. When I compared it to a stock MiniMag with alkaline batteries I thought about making some of these up, but when I compared it to a Sandwich...well there was no contest... the Sandwich(BB500R2H) was brighter with a larger, smoother & whiter beam.
