good choice on picking Convoy C8,i got one on my car and it always stand by no matter what :stuck_out_tongue:

I have a Convoy S2 with an XM-L2 T6 3C on copper with a 3A two mode Qlite driver and AR coated lens. AWESOME light for its size. Fantastic output and great quality.

Loving one of my EDC S2, XM-L2 T6 4C with 1.75A driver.

By the way LSX, where to find AR lens for Convoy S2 ? :stuck_out_tongue:

I got it from IOS HERE

I checked various Datasheets they often state –20°C-60°C as operating temperature.
Cell voltage is a lot smaller on colder temperatures, capacity also. But that’s a problem with every batterytype…

Storage seems no problem as it is stated –20°C-50°C
On minus 10 and below a linear driver will fall out of regulation very quick because of the cell voltage.
But that’s just theory now someone needs to make a discharge test in refrigerator…

I have the 4AAA C8 style lamp in my car with a 3AAA holder with lithium primaries in it…
Not sure how energizer lithiumAAA behave in cold temperature as there is nothing stated, really nothing. But I guess it will still be 1000times better than the old 2D plastic Incan with 10 years old batteries…
Never use these anyway as I normally carry a bigger light in the can holder to play…

:beer: thanks matey

I own a Convoy M1 - real 600+ lumens. Perfect for winter as it will toast your hands at the 8 minute mark and fry an egg after 10-12 minutes. Excellent for cold climates :slight_smile: - not so good in Florida. Bought it from the good guya at Illumination Supply.
