The There Are No Stupid Questions Thread

Jason WW, I am serious. Really want to know.

I just note that many flashlights are made of titanium, copper and brass. In fact I have just bought two Astrolux FT03 Mini brass and copper flashlights. I think they should not be used outdoor when it is raining.

But what about the common aluminium flashlights, and those made of titanium, which I assume are not attracting lightning much. Please correct me if I am wrong.

Just avoid ones with magnets in them, like in the tailcap. That will suck lightning to you like fat kids to a candybar.

It should not be an issue. Unless your holding a metal rod well above your head in an open area, I don’t see how holding a flashlight would have any effect as far as drawing a bolt of lightning towards you. Just my opinion.

Magnets? He said he was serious.

If you keep the flashlight in close to your body at waist height, the lightning will likely strike your head first and flashlight will be safe. If you use an umbrella that will help keep your hand and the flashlight dry.

I am living in Singapore, which is reputed to be the “capital of ligthning” of the world.

I am curious to note that people mention on the BLF whether a certain flashlight can be used in the rainstorm, or submerged in the water for how long; but I have not seen any discussion on lightning risk. That’s why I have asked for experts’ opinions.

JasonWW :smiley: , You are a GEM here at BLF. You have helped me several times, THANK YOU :+1:

Yes and not everybody has the luxury of being able to stay indoors every time a lightning storm happens. But as pointed out above, unless you’re holding it above your head looking for lightning the body material is not really going to matter. The talk of use in the rain or submerged has to do with the ipx rating. Just about any light discussed here is pretty safe in the rain.

Thanks Oli and Lightbringer for your views. They are reassuring and useful to me.

And don’t call him Shirley…

Experts? Nah. Everyone just seems to yell at each other. Loudest person wins. :laughing:

Question: what is the other flashlight forum going to be like now that it has been sold and the new owner is taking over?

Any more details? I’m clueless.

[Noob question warning] If a blue emitter makes everything look blue, does that mean it has a CRI of 1?

Last one to yell before the thread closes wins.

Can I do a makeshift discharge test with a convoy S2+? Just curious if I can before I go for a hobby charger. I don’t need 100% accurate numbers just approximation to test some laptop pulls.

Got an old one that’s 7135 based? Yeh. I’d only try it with a wimpier light, like 3×7135 for ~1A draw. Otherwise the light could overcook itself if left in free air and uncooled.

I have a 6x7135. Just plan on putting it on low(1%?) and letting it go do its thing

Has anyone posted a summary of emitter characteristics somewhere?

voltage, lumens per watt, max current, availability, cri, tint, etc? So many new emitters since the last time I was hanging around here, and I don’t have a feel for what to use for some mods I’m planning.

Maybe try here? LEDs & Other Stuff - (Reference Guide)
