..post up the coordinates of the last know location and give an approximate radius to where you noticed it was missing.
Being a new poster, I'm not sure of your previous experience with clips or EDCing a torch, but I'll give you two centavos from my many years since you opened by saying that you've "learned a valuable lesson".
Though I feel like the newly appointed clip ambassador/evangelist, I would NEVER rely on ANY clip for belt duty. If you wish to belt carry, a holster/sheath is the preferred method. Anything exposed on a belt is subject to a tremendous amount of incidental contact that goes wholly unnoticed, thus your loss. A clip is primarily designed to create a more secure means for pocket carry. It is the natural evolution of just throwing all your junk in your pockets and then heading out the door. The problem with that, besides having to dig around in your pockets, is the fact that if you have to go prone, kneel or sit down your items are at risk of falling out of your pockets (depending of course on where your pocket is located and how tightly you wear your pants). The clip keeps it secure at the top of your pocket and readily accessible. Because the torch is shielded by the pocket, and only the clip is exposed, it takes a direct hit for something to dislodge it enough to cause loss. ..something that should definitely get your attention, but the belt and suspenders types can/do attach a lanyard/tether of some type for absolute safety. I've never needed to go to such extremes *edit* for EverydayCarry(!) *edit* and find lanyards/tethers to be liabilities because of entanglement and general uselessness. Unless you are an avid climber, kayaker, or some such "extreme" sport enthusiast
and actively pursuing those activities, lanyards/tethers are superfluous. Something either goes in a pocket *edit* preferably
with a clip *edit* or a dedicated sheath/holster. I do get the idea that lanyards seem to be very fashion forward for the well equipped desk/keyboard warrior so that should probably be taken into consideration as well.
