This is a 4Sevens Quark 123. It works fine when the head is tight, but when I loosen the head it randomly shuts off and changes output levels

  • I purchased a Fenix and a Quark, kept the Fenix. The Fenix doesnt have all the different modes as the Quark but its built better.

  • is the regular quark a reverse clicky and the tactical a forward clicky?

    i'm confused about the two at some critical points. on the tactical can you scroll thru modes without having to go into program mode?

  • @glennk721 I have a greater idea, it's a TACTICAL LIGHT the head is in low mode when the head is loose

  • I have a great idea, Tighten the head LOL !

  • do you know if this light is water proof?

  • Clean the threads and contact points with a Qtip and rubbing alcohol.
