OK, so I read the review above. It mentions CR123 damage with four CR123 in series. However, nothing is mentioned about battery damage with two CR123 in series. Since Power equals Volts times Amps...the four series batteries have twice the voltage compared to the two series batteries. So, the four series batteries would have half the amps flowing through them compared to the two series batteries. Of course, this assumes Power is constant (close enough)...and in this flashlight that is an OK assumption for the purposes of discussion here.
More amps...more heat. So why didn't the review go into detail on the two CR123 set-up? This setup should have fried the batteries much faster than the "30 seconds" mentioned in four CR123 setup. Am I missing something or was there a lack of basic EE knowledge in the review?
If the two CR123 set-up had no battery damage and the four CR123 set-up had battery damage...then the most likely cause should be one bad CR123 in the four series set-up.
Anyway, I did a very rough test at home with this light...the two CR123 set-up causes the batteries to become much hotter than the four CR123 set-up for the same run time. Much hotter being...I could not hold them in my hand. Anyway, if you use CR123...use four in this light is my experience. BTW, I ran two CR123 for about 15 minutes (stopped because the light was too hot to hold)...they got really hot, but no damage.
The light actually gives great feedback to you...if the tube is hot, turn it off...the lack of a brass liner actually helps with the thermal feedback.
OK, since I have this light...and it is "all or nothing (full power or off)"...what CR123's have the best heat/over-current protection??
If my analysis above is full of crap...let me know...I want to learn.
