Dive Light Care - Scuba Tech Tips: S06E12 

Those are also good tips for storing any battery-powered devices, even unrelated to diving. Thank you.

I am taking a trip to Costa Rica in February and purchased all of my own gear for this trip because I figured it was about time to do so. I love watching your tech videos because they have helped explain the in's and out's of the gear and how to wash them properly after your dives so they stay in excellent condition. Keep making the great videos. Thank you!

Alec, you area wealth of information that has helped me greatly in my diving experiences. Thanks for another awesome video!!

advice that is so basic, so simple to understand yet so informative and effective, it boggles the mind,, I'm a 56 yr old freshwater diver of only 2 years and night diving on wrecks is my favorite, it never once dawned on me to service my light like my regulars, thank you Alex for sharing your decades of experience

Hi Alec, Thank you so much for this video. I decided to buy me a dive light after watching your video because before this I have no idea how to take care of them. You are the best and I have learn so much from you. Millions Thanks!!!!!

Thanks Alec, another great video, love getting notifications for tech tips

Hello and thanks for another great video! Many modern lights have replaced the switch with a magnet on the exterior, activating an internal switch. I found out that in most cases the magnet is exposed to contact with sea water, leading to rusting and finally corrosion that deems the light unusable. My treatment is to insulate the magnet, usually with a thin layer of hot glue, that prevents contact with water. Of course, you need to dismantle the switch in order to do that.

Great advice ! ... Thanks Alec .

I was not aware of this. Going to do this from now on... Thanks

Some great information here, as always! Thanks Alec. Reason I found this tech-tip is because I was searching about for another dive-light related bit of information. What I'm wondering about is whether or not it's a "myth" these days with modern lights and never turning them off during a dive. Back in the day (not as long ago as you, but certainly a few years ago now!) I was taught to always turn on my light before jumping in, and to never -ever- turn it off during the dive. This was mostly for night dives. The explanation given was that lights, if they fail, usually do so when they are first turned on. This is certainly true with filament lights where the filament undergoes a massive heat-shock when turned on. How often do you come home at night, flick on the switch, and *bang* the light goes? But it almost never fails once its on. Same thing. So my question is - does this reasoning hold for modern, LED-based dive lights as well? Certainly my (young) dive guide in Malapascua the other month thought so (but wasn't at all concerned that nobody had a backup light nor a tank light...)!

Noooooooooooooo!!!! My fiancee had a light just like the one you showed in the video. We've had it for a year now and we've never taken the batteries out of it or opened it up!! After seeing this video I ran upstairs to see if it was still good.... :( It doesn't turn on and I'm not sure I can get the batteries out. :( And I feel especially bad because I remember you personally handing her the light last year as a prize during the Scuba 2000 treasure hunt/pumpkin dive. I apologize profusely and promise to never let that happen again. :S Thanks for another great tech tip Alec! Can't wait for the next one.

Thanks! I had no idea about rinsing the light and hydrogen build up. Going to wash mine now and find some ziplock bags.

Great content thanks, love watching your presentations. What about factory sealed dive lights? Should we be cleaning the external diodes with rubbing alcohol to prevent corrosion?

Great video. I just bought a fusion 530 light and great tips. With devices like these strobes and higher end led lights how often do you replace the o rings? Cleaning and lightly lubricating isn't a biggie for me but I wondered. The great things about these lights is many have double o rings for extra protection (granted we do our part too).

Really helpful video! Thanks!

Another great vid ! ... would be cool (dont know if you did already) to have a vid about which light should I buy .. and how to recognize a good one pros and cons for situations (im personally interested in the ones going with around the hand type of strap)

Hey Peirce, how about Dive knife care for a Tech Tip? Another great video by the way.👌

Great tips as usual. I had this problem with a very expensive dive light, with a seperate battery canister. 200 euros for new batteries, because i left it closed for a week after the dive.

Great tips! I'm about to go on my first night dive this weekend. Could you tell us more about how you guys did night dives back then? It sounds pretty sophisticated, with the tractor battery and all.

If you do leave batteries in a uk c6, and the batteries corrode, how do u remove/dissolve the corrosion?

I use eye shadow applicators to clean the o-ring seat and housing...cheap and effective.

great tip and sure enough one of my light started corroding... But could you prevent at least the Acid build up by putting dry air in it (say from regulator) and never opening it (until battery are dead) ? I have a dive tracker as well, but those are clear plastic tubing (with electronic diagonally centered) and cork material near the cap (for moisture control ? or padding) wondering if they also should be taken apart between use. It's tedious to do that when you dive every other week or so, and may weaken the seal, or require cleaning/silicon each time...

Can you do an episode on drysuit care for pre and post dive, as well as storage.

How does this apply to torches with integrated rechargeable batteries, that don't open up easily?

Alec, there is no tell, how many dive light I have found stored for 6 months or more with the back end blown off due to hydrogen gas build up. BTW, some dive light have like little carbon pellets, inside a retainer spring inside. What are those for? Gas absorption?, neutralizer???

Hey Alec! Love your videos but one question on this one. The red flashlight looks like a MagLite and according to their site they are not waterproof. Have you taken that diving and if so how deep? I have like 10 of those all over the place and I'd like to use it if I could.

Hi, Alec, is this something that should be done to other battery-powered devices, too, like cameras and dive computers, or primarily for dive lights?

Would it be better to not reassemble the light so that the o-rings are stored uncompressed? On so e of my torches and flashed I remove the rings and put them jn a zip lock bag if I am not using then for quite a while. Is this overkill?

Hi Alec. What about dive lights that have a switch on the bottom? Still ok to rinse those with freshwater?

I am considering to get my first BCD, looking at BP&W or back-inflation BCD, any suggestions? I am scared by the complexity of BP&W but heard that they go a much longer way

Hey, Kevin! Understood??

Hi Alec, would like to ask, with a mechanical head rotary switch, can I turn it off underwater? Or will I run the risk of water seeping in? By the way, I have an Orcatorch D560.
