Since I am making modding plans for my existing mags, I thought this would be a good house light. You are correct that the 3C is brighter, it was not on the Sears site and I could not find any details about the differences on the Streamlight website. I did find the info and will problably wait, especially since my wife told me "no more flashlihgts today in Sears :thumbsdow (purchased 3AAA Worklight for Mag upgrade) and I have parts coming in the mail from 3 sources soon...man she will not be pleased :touche: I will check around locally.
