Hmm, would like to read some research done on this, never tried to use light for that much time outdoors in bad weather, so Im curious whether it matters or not what kind of light you bring outdoors!
It’s how you keep condensation out of a multi-thousand dollar camera lens in a temperature transitional situation. How is it any different? Believe me, a $2,000 12” long 3” diameter lens that’s been in the direct sunlight for hours can seriously pull some humidity out of an air conditioned room! Exactly what sports shooters do with $12,000 lenses. Just wondering why you think a $30 flashlight is so special?
Hot aluminum and hot glass in a damp cool environment, with sophisticated electronics (my Image Stabilization system is more than $500 by itself), looks like a very similar situation to me!
Yeah, think so. Drop the light in a zip-lock bag, squeeze out excess air, leave it to cool. I’m betting you’ll see problem solved.
this phenomena can be observed with half empty mineral water bottle (or just any other plastic water bottle).
when the half empty bottle is stored in room temperature (25 celcius or higher), it can creates fog by itself inside the bottle on the dry surface part eventhough the bottle cap is tightened. be sure it is water tight because otherwise there will be leakage everywhere when carrying.
need some coffee now, but the laughter is a good way to wake up!
Sorry, I did read all of it but must not be awake enough to interpret what I’m reading. Have no recollection of your post, but remember the ones before and after. Sucks getting old!
My 12xT6, Xiaozhi, 3T6 and Warrior recently spent a few days in the exact same conditions (moisture/wet tent, night rain, condensation inside the tent, and all were heated up a lot before bed) and all survived with flying colors! Now dont ask me why I needed so many high powered bright lights when there were only two of us most of the time! I withstood lots of similar questions/female complaints on my lights and extra batteries and “reasoned” in my “defense” it was because my dogs also each needed a light.
I wonder if the damp iPhone trick would be a cheap easy way to avoid this problem. Stash it overnight in a zip lock bag with rice. Cheap and easily acquired desiccant with the added bonus of being an extra food source.
I wear g-shock because I don’t take off my watch, ever, except to clean it with a toothbrush, or to do some settings or something before putting it back on, that means all bathing and showering, swimming, desert, mountain conditions, weather, everything, and I have never had a problem with g-shocks.
Several weeks ago we were in the Peruvian Amazon and ran 3 cheap Costco headlights, a Convoy S2, and a Zebralight sc52 for about an hour continuously in the evenings. We didn’t have condensation problems with any of them. It’s fairly humid and the temperatures were in the low to high 60s (just guessing, we had to put on jackets at night). Does there have to be a bigger difference in temperature to get condensation?
I didn’t check for condensation so it’s possible there was some and I just didn’t notice.
I took my EA4 tent camping last weekend. We got some rain but the light didn’t get wet. I was more worried the switch would balloon. It did fine, but I worried about it, so I bought a D40A when I came back, just for good measures
