IMHO, dont waste your time and money with someone who wont take 10 seconds to answer you. I almost bought this light in spite of the horrible customer service till I read this review . Now Im very glad I passed.
Convoy is coming out with several lights that are far better, and their rep is one of the best on this forum for answering questions and providing the type of light combinations flashaholics are asking for. 【convoy】SFT40 5000K back in stock (sufficient) Also read the last few pages of the thread for the latest and what is in production. GREAT STUFF!!!
Good luck in whatever you decide.
