Do you want a measured 350 meters or to be able to clearly see to 350 meters?

The Lumintop GT mini is already a C8 sized thrower with a FET driver and xpl-hi. The Emisar D1S is very similar. Both can throw out to a measured 750+ meters.

The L6 is not much of a thrower. Stock is a measured 450 meters. Highly modded is about 830 meters. If you slice the dome off you might measure over 1000 meters.

For hunting you might want to check out the Jaxman Hunter series. They are narrow focus, long range lights.
