I just got an old Streamlight SL-20X at work. I have it on the charger now. The beam didn't look so hot when I first turned it on. I am thinking that the battery is sort of worn out. I think I actually have a spare stick to put in it. I am thinking of getting an SL-35X lamp assembly to pop in it. Can anyone advise where is a good placed to get the lamp assembly. I seem to recall a year ago or more that some place on the web had them for $12 plus $2 shipping. Does anyone recall where has the lamp assemblies that chaep?
