Must be very small. About size of AA battery. TI , Damascus or Mokuti. 800-1000 lumens high cri neutral white. Rear click or twist. Must be able to get in 30 days. New. I saw what I am looking for at $600 on Amazon but I think it is Chinese mass produced. I will spend up to $2,000. I will consider used if in brand new unused condition at a savings not markup. I am not sure if the output is wishful thinking? I would even consider copper. I am very serious about this if it exists. Otherwise, how close can I get? Thank you
