I decided to do a teardown cleanup of my Lambda Illuminator Adrenalin Pro 2AA LED light last night. Part of my torch maintenance routine is contact and switch cleaning. I took apart the tailcap clickie switch, removed all the metal parts and set about cleaning with 90% IPA and then deoxing and protecting with Deoxit D100L connector and contact treatment from Caig Laboratories. This is a red liquid that "Improves conductivity, cleans, deoxidizes, seals & protects electrical connection." Swab on a little with a Q-tip and wipe off the excess. Reinstall tailcap innards, screw back on and click. Wow!!!!!
The light is clearly, visibly brighter. Not believing the effect, I pointed it right at my eyes and clicked...Aaaiiiieeeee!! Spots! My LI-AP has never been this bright. Whereas before the cleaning, I would occasionally look down the barrel and click it on just for fun, I could not even look at it momentarily now. Yeah, I'm strange. Before, it was very bright but I could stare at it for a few seconds but now the light is almost painful to look into, I have to turn away immediately.
Lesson learned: take the time to occasionally tear down and clean the switch and contacts in your lights. Even if the switch and associated bits are supposed to be self wiping/cleaning, oxidation occurs and can drastically increase the resistance, dropping your volts(?) and dimming your light. This is especially critical if the assembly, such as the Brinkmann clickie, has several small parts and one very thin copper piece which is probably high resistance to begin with. I imagine the effect is dramatic with LEDs because of their low power consumption. Three alkaline Ds have much more juice to push.
For heavily tarnished copper bits and the like, I use metal polish followed by Deoxit. I think I might have to take apart my Mag switched since their internals are just chock full of thin metal bits.
