I’ve just finished listening to the video and now you tell me your nearly finished? Are we in some sort off time warp? I’m sure I read somewhere that it was hot and you may take awhile to finish this as you may only get an hour in the morning. Or am I asleep and dreaming?
i like the looks of this light now. black and silver…oakland raiders color. plus it has a side switch! never even heard of this light till now, looking forward to beam shots.
It has a momentary switch, but the tail cap has nothing to do with ground. The circuit is complete without relying on grounding the body. When you have four cells in series, both the positive and negative end up at one end (the top), so the driver/contact plate has both positive and negative in it and the circuit is complete. You can’t isolate this light unless you take out the batteries. (in stock form, or modified form).
EDIT: That is why the EA4/8 has a clicky and smd built right into one switch. The clicky shuts it off (isolates) and the smd controls modes.
