How to Lubricate An LED Flashlight Correctly

Even LED flashlights needs general maintenance. Here's how you keep the threads clean, and the light running as it is intended to.
Nyogel is what I'm using in this video, and it's what most flashlight experts recommend. Amazon sells it (among other flashlight retailers). Here's their link --- amzn.to/2pQlFgO

More importantly, take the O-rings off, clean underneath and re-lubricate them!

I am here because i just bought 5 FL and I don't know how to do maintenance.. All of my FL are abiut 2 months old.. Thanks for making this video.. this deserve mo likes and views.

You can use the lube on the contacts too, you don't need deoxit, the grease doesn't inhibit the contact at all. It also helps the metal parts to remain water-free at all times.

[@westsenkovec]

It increases the resistance and it lowers the performance significantly.

[@TheMUSICFANATIC67]

I have lots of eagletac. and powertac. flashlights. and I have been using super lube's multi-purpose synthetic lubricant with syncolon (ptfe) and I have to say this is the best product on the market:):)

[@Lightsngear]

TheMUSICFANATIC67 Thanks for the recommendation!

[@TheMUSICFANATIC67]

your very welcome!

[@RingZero]

You don't use silicone to clean it, silicone acts as a lubricant.

[@Lightsngear]

The video is about lubricating, not cleaning.

[@mk-ey2kp]

Old vid but you seem to know. I got some surefire scouts that flicker. Supppsedly the spring in the tail cap has connection issues. What grease/lube would be good for connectivity between the battery and the tail spring.

[@Lightsngear]

I don't know of any specific application that would lend itself to a connection issue. The Nyogel product that I use to lubricate would probably be fine.

I have watched this video three times. Just keep thinking I am missing something. No.. Non-conductive grease to clean, lub metal electrical connection. NO NO NO NO .. Use good old 99 percent alcohol to clean, and then DeOxit Red to Lub. You could use the DeOxit grease which has copper particles but I would not, you want clean metal on metal connections for a flashight connection. Could use the non-conductive grease with the o-rings, maybe that is the confusion.

I have so many paintball lubes from my years of playing that seems to work okay. Most of my flashlights are Nitecore so I went ahead and just bought a container of Nitecore SG7 grease... figured if thats what they use in the factory, I might as well use that my self. The Lube you are using is supposedly the best though.

Crixus The Gaul know a good day Union

[@BenBratzBoy]

Very good video!! ;)

[@arindambhattacharjee1121]

Can I use any silicone grease?

[@ThPappas]

Thank you for the video.

[@jon_byler]

Nyogel that you show in this video is a petroleum based grease hickened with silica. It's not polysilanes/siloxanes/silicone. look at manufacturer's data sheet. It's supposed to be good stuff, but it's not silicone.

[@Lightsngear]

Thanks! That's good to know.

[@JackNWhite92]

The point of the silicone grease is to lubricate the O-rings, not the threads.

[@Lightsngear]

True, thanks for mentioning that.

[@TheFrozenMind]

But you can also lubricate the threads as well, to avoid metal to metal contact.

[@JackNWhite92]

TheFrozenMind yes, but you can also use anything else that doesn't react with the O-rings, the purpose of using silicone grease is to lubricate and prevent wear on the O-rings.

[@TheFrozenMind]

can you suggest other grease I can try?

[@Lightsngear]

+Ole Andreas W. Lyngvær I heard where others have used petroleum jelly! Bad move from what I've heard.

[@michaelaffdhan3855]

I have Krytox 205g0 and Super Lube oil from my keyboard hobby, can I use those instead?

[@Lightsngear]

If it's silicone based then yes

[@starbusterninety2469]

Will it damage the electronics if it gets on the circuit?

[@Lightsngear]

I haven't allowed that to happen, but I wouldn't think a small bit would be harmful.

[@anildasr5310]

Isn't o ring lubrication needed?

[@Lightsngear]

Yes you can certainly do that.

[@countdankula6740]

can i use dielectric grease?

[@Lightsngear]

I hate to not give you a good answer... but I'm not sure what kind of grease that is.

[@clonazepam04]

Dielectric grease is silicone grease.

[@callofduty60]

I wouldn't - If I'm not mistaken, dielectric grease is non-conductive. You will be better served with a grease that is conductive, due to the nature of a flashlight especially around the tail cap area as you do not want to impede the electrical current in any way!

[@EduardoBach01]

You can safely use any ptfe grease as it doesn't inhibit the electrical current to pass. The contacts don't need a great surface area to conduct electricity, when the metal parts touch it will work because the contact area will press anything away and the metals will touch. The dielectric greases are more a surface protection than a full prevention; it helps to prevent sparks on high voltage applications, it's not the case with a pocket lamp. ps: smear some dielectric grease on your fingers and put in a socket; I'm pretty sure your next post will be from heaven :P haha

[@javiermac5885]

Keep the electronics moist ?!?!?!?!?

[@Lightsngear]

lol -- no.

[@mr2bmw]

Can I use brake grease?

[@Lightsngear]

Not to my knowledge, no.

[@louiemarelinon6937]

Im here because of flashlight but i was talking about other flashlight

[@flamed_bars7299]

THE WIRES

[@gearreviewn3747]

can you use vaseline

[@Lightsngear]

No, you can't. It's too greasy. It's just like buying crap batteries, you don't do it. You pay decent money and buy quality protected batteries that are safer to use and last for years. In this case... you buy Nyogel or something specifically recommend to do the job properly.

[@gearreviewn3747]

Syrbuff ok thanks I will get some of that because I have a lot of flashlights to and they need cleaning

[@tyronewalker5764]

Once it gets above body temperature it starts to liquify.

[@zippy3711]

Everybody knows a flashlight needs to be lubricated. WTF !

[@Lightsngear]

zippy Yeah...this video is kinda old, but you never know, there are a lot of misinformed people who know nothing about this stuff.

[@flamed_bars7299]

THE METAL WIRES OF MINE BROKE Wait nevermind it was fixed.
