... Some confusion there i think.
The low voltage cut-off comes in at 2.7v.
It does not matter if the light has this step down or not the torch still switches off at 2.7v
The difference is, with my early SC600 the light will stay on 500 lumens until 2.7v then turn off.
With this auto step down it'll just keep stepping down the output until 2.7v then turn off.
It's pretty pointless buying a 500 lumen torch is i can't use 500 lumens when I want to use it.
I will use the MKII as my EDC and keep my MKI for outdoors stuff.
It's a shame though as this ruins what is otherwise a pretty fantastic torch.
I have a SC600 Mk-I with the step-down feature. It's virtually impossible to predict when
I have accumulated around two hours of Turbo/High run-time and trigger a step-down into
medium, but, I have repeatedly clocked more than an
hour of 65 lm Medium between the
first drop-down from high and the second drop-down into low. The corresponding battery
trigger points are something like: 3.370 volts and 2.915 volts, respectively. YMMV
I've never had the patience to clock after dropping into low, but I guesstimate around
2 hours of 2.8 lm low between 2.915 volts and the 2.700 volt cut-off. And, the lowest
0.1 lm low should last around 20 days. Enough time to safely navigate out of a cave!
The point I'm compelled to make is that we can safely EDC Turbo/High modes knowing
that we will always have 1-hour of 65 lm Medium plus 2-hours of 2.8 lm low
in reserve
if we unexpectedly drop-down. Imho, that beats the hell out of cluelessly wielding
Turbo/High modes until one is unexpectedly thrust into total darkness. Murphy's law
says that it would happen at the worst possible moment too.
