The There Are No Stupid Questions Thread

Hey just figured a thread where old and new members could hang out and ask and answer any question without judgement could be nice.

Only restriction: common sense, some morals. Otherwise anything goes I guess, maybe keep it flashlight related?

Ask away…

EDIT: No it does not have to be about flashlights at all

Don't give up on your dreams,
Keep dreaming.

In a single cell flashlight using a boost driver. Is 3000 lumens about the maximum performance we can muster from an xhp-70.2?

On what type, kind, style(?) of flashlight do we need to feel it necessary to use protected cells?

What gives li_ion a 4.2v charge? Why is it not 6v or whatever random volt we need? Why 4.2v or 1.5 for alkaline and 1.2 for Nimh?

Does anyone really think we are alone here on earth, there are a estimated (possible) 100 billion solar systems out there.
Is it naive of us to think that earth is the only one that got it right for life.

Per current estimation of galaxies in the universe is 2 trillion (yes, trillion with a “T”) odds are that we are not alone.

Think of a battery like a box of food. The V are the calories or “fat” each material (food) gives of a certain number of calories. li_ion is like a donut/pizza while the others are more like an apple. Also in a battery there are “cells” these cells are like lets say a dozen donuts in a box the donuts are the cells the box is the battery. For example in car batteries there are six cells with 2v that gives us a battery “box of donuts” of 12v. The V charge depends on the characteristics of the materials used.

Keep dreaming.

I’d say that it’s necesssary to use protected cells in any light that uses cells in series, and it’s advisable to use protected cells in any single-cell light without low-voltage cutout, such as those that can take either AA or 14500 cells.

Should protected cells be used in lights that use multiple-cells in parallel?

Why do some light enthusiasts rave about specific flashlights to a point I picture them with a tattoo of the light they are debating over?

This is a good thread, I’m excited about this. Not a hellova lot of answers but good questions. Some legitimate, some not.

But thanks, Skinny Tie, That was what I wanted to know. You are the exception.:)

If you could fire a laser in one direction of the cosmos and it didn’t disperse or hit anything that would absorb it, given enough time. would you see it coming from the opposite direction from where you sent it?

How close to the ceiling does a fly get before it flips upside down and sticks?

And will a Q8 blind it?

Is there something like Moore’s law with LED emitters?
I’ve refreshed many old lights with newer emitters and the increased output is amazing.
Will I look back on today’s emitters 10 years from now and laugh at how weak they are or has this technology been nearly pushed to its limit?

Not asking for crystal ball answers, just wondering if anyone has deep knowledge of how far this can go.

As long as you have most of the other prerequisites:-

A camera that cannot focus
Shaky hands
A lack of corroborating witnesses
Redneck ancestry

......I think I have a lot of those prerequisites.  Photos to soon follow of blurry images of something that really is just a  blurry image and to others a sign of big foot.
