TF flames barely work. You have to go unprotected and will need to solder a tab on the end to get it to work. But it is a great light and the output blows away the H2.
Not as far as I know. When I first got mine(b model- I think d is older model) I thought it was DOA. Then I tried a non protected and it worked. I found the issue is the tail cap does not make contact with the body if longer batteries are used. It will work with a Flame if it is screwed very tightly. You could put a blob of solder inside the tailcap to help it make contact. I don't want to turn people of buying it as it is my favorite headlamp but they should be aware of the battery issue.
Yes. What edc said. Will trustfire protected 18650 work with this? What else? The one with edc does but we are not sure if it’s the same as this group buy.
If this is indeed a "B" model then I'm in! I'm confident the protected TF Flames will fit and I have lots of Rev Jim's Panasonics that will work just fine.
