Hello everyone,
I’ve lurked on this site for quite a while, sporadically for the past few years, and I’m finally joining the club! (I’ve got an Astrolux FT03 and Convoy S2+ on the way)
It’s amazing how much the lights and emitters change so much over such short periods of time.
I do also need to get an unreliable light working again. I inherited it from a friend, anyone have suggestions on which forum category I should ask for help?
Anyways, hi everyone!
Welcome to BLF, greenteei89. 
You would need to specify which light and what is wrong.
For any kind of questions you don’t know where they belong, there is the The There Are No Stupid Questions Thread
Welcome to BLF!
Watch your wallet since it is very hard to resist the amazing lights and deals you’ll see around here.
About the light you want to fix, please create a specific thread with all the details and pictures that may help others to provide appropriate answers.
Have a pleasant time at this friendly forum, greenteei89!
Welcome to the forum . 
Welcome to BLF greenteei89! Good choice with the Astrolux and Convoy flashlights.
