To cave divers, wreck divers and deep divers, their light is without a doubt one of the most important components of their dive kit.  In cave diving especially, a powerful and reliable light can be a life saver.  Traditionally, a decent canister light would break the bank for a diver.  On top of that, if that diver were to need different beam angles depending on the dive environment, they would need a separate light for each environment.  Finally, if something minor were to give out on the light, it would be ruined or would need to be sent back to the factory.

Nanight, made it their mission to construct a light with an answer to all of those problems.  The Nanight Tech 2 has user interchangeable lenses with 4 different options for beam angles, the same light you use in murky conditions can be changed to a 120° video light in seconds.  Next, they made all of the main components of the light user interchangeable so you can order a part and replace components as needed.  Lastly, Nanight has managed to make this reliable, high powered 4000 lumen light available for a price that is absolutely unbeatable.  For that reason, it is quickly gaining popularity, especially among the cave diver community.

Nanight can make either their C3 or their Tech 2 with an E/O cable rather than the external charge port. This gives you the ability to run your light head with any canister that has a 5-20V output.

This is popular for divers who use a big battery canister with multiple outputs and want run, for example, their heat vest and one or more lights from the same canister.

*Nanight uses 14.4V so the battery indicator and the step down is set up for that. You can let Nanight know what voltage you need to run the light at and it is possible for them to update the firmware.

*External charge port is more cost effective and redundant than E/O cable.
