I have purchased 3 photon freedom lights. $60
One is in my PSK, One for my Wifes, and now one as my EDC.
I could have been frugal and stuck with the batterys and LEDs.
$10
The dimming function sold me on the freedom.
I don't even want to add up all the other stuff.
I am going the cheap rout on the 55 gallon drums for water storage.
$60-80 bucks new, used from local coke bottler $5.
