I went to Epieon LED bulbs (LEDCORP) in my two and three cell maglights quite a while ago, but the SMJLED is way less pricey. I found the Epieon LEDs to be a great alternative to incandescent bulbs. Just as bright or brighter, easier on batteries and not as fragile. My only wish is that they could fit in a regulation circuit so the light didn't dim with use just like the original bulbs.
