If you're looking for a great C8 at a reasonable price, this light is what you're looking for. This light has a black hard anodized finish, square-cut threads, and is one of the best C8s out there, at any price. The smooth reflector provides a tightly focused beam for maximum throw.
The Convoy C8 features a super-bright and throwy Cree XP-L HI emitter, and a reliable 7135 based driver. If you don't want strobe, no problem, you can easily disable it or enable it yourself (see below for instructions).
This light works with flat top, button top, unprotected, and some protected cells. The Protected NCR18650PF & NCR18650B sold here all fit in this light. While the Protected NCR18650GA usually fits, it is very tight, so many are not happy using it in this light. Some other protected variations of the same cells may not fit.
