You are adventuring deeply into a cave. The journey could take a few hours, and being a newly explored cave, there is a significant chance of either kicking up silt or having your exhaust release it from the roof of the cave. Your light is one of your most important tools, without it you will be diving by brail in an unforgiving environment. You need a light that is dependable, has a great burn time, and has a tight beam angle in case it has to cut through silt.

The Nanight C3 is a durable and heavy duty dive light for any dive environment.
With an 5° spotlight, the light provides an incredible reach even in bad visibility.
The canister mount is a robust design of A4 Stainless steel and the goodman handle is made of high grade carbon fiber. It has a burn time of up to 7 hours and is extremely high quality, making it popular among the cave diving community.

The light is equipped with simple reliable magnetic switch without any complicated mechanics, that can be used to change the power output of the light and will sustain years of use in salt water.

*The C3 is optionally equipped with a Charge Port, with a bayonet mount cap that makes charging a breeze. The charge port connector is completely waterproof, even without the cap.

E/O:

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.
