Maybe I'll grab the body off the other 35 that hasn't seen the light of day.

Anyone ever pull their boss out , click the switch & get no response? Gotta tap or shake it, then it lights up.

Let me know if its the switch or not, we'll get you fixed up either way!
Information
We tend to do things our own way. This leads to the extraordinary but also leads to confusion when its wholly different from previous approaches. Todays example: the engineered gap of 0.010", between the BOSS head and body.
Batteries have two poles/ends, driving electricity to the LED. Positive goes up through the spring/contact. Just about all lights rely on the body to conduct negative up around the cell and back to the head. Many designs use the head/body threads for the final connection. It's already there and works out of the box, but over time contaminants clog up the threads, blocking the power, interrupting, or cutting off power. Cleaning the threads fixes the problem but your light is unreliable in the mean time.
BOSS (and previous TorchLAB designs including Moddoolar) also conduct negative through the body. However, instead of going through the threads, power is directed to a dedicated and protected contact ring inside the head*. The threads can get as dirty as tar with the worst non conducting lubricant, and as long as the top of the battery tube reaches the contact ring, it will turn on. Ensuring this ring is always in reach requires a certain amount of offset with the body (the gap).
*this is the outside ring shown on the left:
im able to completly unscrew the head of my light with it turned on. power stays on until theres nothing but air between the head and body. it seems that the negative contact ring comes in direct contact with the head. so if the spring touches the cell, light comes on with the slightest contact between body and head.
edit- im not implying that the gap is unintentional; just wondering out loud if its necessary
Well that would make allot of sense as to what i am seeing 😀.AFAIK, the 219C and XPL run on the same maximum output from a single cell configuration -- 17W (1900+lmn).
