Response to Re: Meanwhile back at the Ranchco John-O.... Dead Dot? NO! NO you're not allowed to die!

a couple different ways to adjust brightness.
This unit uses a PWM to adjust brightnes and EEPROM to save brightness settings (there is your memory) The switch is a momentary, normally open.
Even when the switch came loose and couldn't be shut off it ran for a whole week on the original 2+ year old battery!
I took this as an omen that many squirrels must die....

Another dot with the turret/batt holder/switch/brightness 1-11 switch WILL be dead by morning.... brightness must be controlled by something which dissipates current.
I'll definitely stay away from that switch configuration from now on, unless they advertise uber runtime.

I don't know about brands, just bought this from a pawn shop on a whim.
Too many guns, not enough optics!
