Can you guys just give it a break? I'm one of the biggest SF fanboys around, and you won't catch me trashing threads. I've had several things made in China that are very good quality...Including lights. And I've also had quality issues with things I've purchased that were made in the USA. And...oh...btw....Our precious SF's may be made in the USA, but not everything in them is..ie:..emitters, electronics, etc. Better just throw those parts away guys.
Do you know how many SF clickies I've had to fix or replace? I even had to send an E1L back to be replaced because the tint from the emitter was such an awful puke green. Don't you guys hate it when people who like other lights trash our SF threads? The reason SF gets picked on so much around here is because of people with bad manners like you. The OP came here for help...and all you can offer is immaturity. So Please..come on and grow up now. :shakehead
To the OP. Try cleaning all the threads and electrical contacts...including the front of all tube openings, and where they contact, with DeoxIT if you have it. I did this to my NDI, and it works very reliably as it should. If you are not successful, contact the vendor you got it from...or
post over here in the NDI thread at MarketPlace. I am sure Ms Wong will be willing to help you out. I love my NDI, and highly recommend it to anyone looking for a nice, well built AA EDC light.
What's wrong with it? Not made in USA...
Can't believe you actually bought that light, my friend.
