We, and several flashlight manufacturers use highly rated Super Lube on flashlight threads and Orings. We offer two choices of Super Lube - Grease or High Viscosity Oil (Gel like consistency) - we prefer using the high viscosity oil - but, it does require more frequent application. The grease on the other hand is pretty much a once a year or so application depending on use and environment.
In either case - only a small-match stick head size or smaller drop of grease/oil is needed for most applications... on our lights the best use is on the body tube o-rings to make for nice buttery smooth tail cap and head twisting. (note as lubricants do tend to be dielectric in nature - for best light performance do not apply grease/oil to the electrical contact surfaces at the front or back ends of the body tube) Either of the below tubes will typically last you for years.
Super Lube® Grease is a patented synthetic NLGI
grade 2 heavy-duty, multipurpose lubricant with PTFE. Synthetic base
fluids and the addition of PTFE micro powders combine to form a premium
lubricant that provides longer life protection against friction, wear,
rust and corrosion. Super Lube® is compatible with most other
lubricants and will not run, drip, evaporate or form gummy deposits, and
will not melt or separate.
Super Lube Oil with PTFE is a premium, synthetic oil with suspended PTFE particles that bond to surfaces of moving parts providing protection against friction, wear, rust and corrosion. Ideally suited for industrial machinery and equipment, it is safe on metal, rubber, plastic, wood, leather, fabric and painted surfaces.

oxidation and corrosion. If the metal surface is discolored, it is
severe. DeoxIT dissolves the contamination and protects the surface. For
reference, DeoxIT has approximately 20% cleaning action. Key Feature:
