They're called 'wonder batteries' because while in the back of beyond you'll be wondering how long it'll take to have some shipped to you in a one horse town where no one sells wonder batteries before you can use your 'super torch' to see in the dark. An activity I'd class as mission critical. Reliability and Availability the watchwords of outdoor equipment. Whatever it is, it must work when you need it to, and the stuff it eats must be available everywhere.
The NiteCore D10SP runs on 'AA' which while not having the output of wonder batteries win out by being the most commonly available battery on earth, and a lot cheaper too.
Let the Unboxing commence:
One of the clever things in the design is the contact-less switching (Smart PD System) where instead of the contact switches found in most electronic products Nitecore are using magnets to make the connection; meaning there can never be a spark between the switches parts (reassuring while looking for gas leaks) and with no moving part to fail reliability should be excellent.
Once the light is switched on, pressing and holding the tail button cycles through three brightness settings: 130 lumens [1 hour], 35 lumens [6 hours] and 2 lumens [100 hours]. If you double click the tail cap it also has a very neat strobe function which would be very clearly visible, and run for a very long time in a survival situation.Features:
