This is good, cheap glow tape-Mark flashlights to find in the dark

I bought a tape with the same pictures and similar price. It doesn’t glow forever but glows for long, I haven’t determined duration.

Wow… that’s a sad story & a pitiful commentary on their employer. :frowning:
Thanks for sharing, I had never heard of this.

I knew about the Radium Girls, anybody who doesn’t, and thinks your job sucks should click that link.

ok i am OP

here is what i know
it is cheap - it cannot be tritium

it does glow all night - maybe it would eventually fade but i have not tried to keep any in the dark for a week to see what it does

when i said it does not need light charging, that was for 12 hours

when i was a kid though, i had an old big ben westclox alarm clock, and you could see sparkles on its glowing hands, if you looked very closely
with good kid eyesight
i was told, maybe this is wrong, that those were gamma rays hitting the phosphor stuff, making it sparkle
i don;t really know
maybe the thing had some radium in the paint, this was the 60s, and it was really radium decay

i assumed when the new tape lasted all night, that it was this gamma hitting phenomenon
now i don;t really know

but i assume radium is also out, due to expense and legalities

maybe i will put some in a dark box for a week and see if that is still visible at night in the complete dark like the 12 hour glow

i will probably find that it does gradually fade out, it just takes more than 12 hours,
there are no gamma ray sparkles, and what i saw before may have been radium paint,

wle

The show I saw, not sure if it was the same one, was really sad. It showed pictures of the girls faces. The ones that survived were a mess.

/\… That is horrible…… :frowning:

Yes I read the book - it said some of the workers actually glowed in the dark - you could see their skeletons through their skin.

This was before they seemed sick.
The radium glow was thought to be healthy.
There were people who knew that was a lie, the bosses, but they of course didn;t say it.
They at one point told the workers not to ‘point the brushes’ with their lips, and gave them rubber doohickeys to do that with.
But the workers didn’t like those and went back to lips.
The bosses knew all this and didn’t enforce it, since that made the work faster.

The book is just called “Radium Girls”. It’s fairly recent. Great book, terrible story.

There is a movie that came out last year. Not sure if it’s available on any of the streaming services or otherwise.

anybody have a gieger-counter meter to test this tape for any extreme nuclear radiation! its made from the elephant’s foot probably.

Forever? What does it mean?
Comments above says it must be around 12 hours, but not forever.

This sounds dangerous, but I’m quite interested.

So what’s that exactly?

Emiriya, welcome to BLF! I’m curious how you found us. Have you been lurking for a while? Surely this thread didn’t pull you in! :stuck_out_tongue:

The tape is probably just glow-in-the-dark tape. The listing has a lot of dubious claims, some of which seem to contradict each other. But, in the end, it’s probably the same stuff we’re used to seeing. You light it up with some other light source, and it re-radiates that light for some time afterward.

Language. Often an issue with these listings. They mean “no need of power energy” in that you don’t need electrified light to do the job of the glow tape. Not that the tape doesn’t need light to start glowing! That would be ridiculous.

Btw, 10mm width is a bit narrow. Some people overlook that, only paying attention to the length of the roll. 19mm or wider is better, to cover most applications (for a contiguous piece you trim, versus assembling multiple strip pieces).

For those interested, here is a glow-in-the-dark powder that is capable of being charged up by body heat. It is claimed to be the world’s glowiest glow pigment.

Because I know this stuff exists, as well as some other products I’ve seen, I don’t have any trouble believing the glow tape can show some amount of light all night long to someone with dark-adjusted eyes. :wink:

i’m testing it, put some in a dark place, will open in a few days in dark and see what it does

it is so cheap, it is almost certain to be just plain old regular glow in the dark stuff

the tape seems to me, to glow longer because the glow stuff is thicker on a tape, than is possible with paints.

i was just assuming that if it is visible after 12 hours, it would go on forever - we will see.

“Oooh, lookit that! It’s over a day and still glowing! It must not need any power at all… ever!”

“Oooh, lookit that! That light’s so bright! Must be 10,000,000 lumens!”

QED.

I guess her sig line shows how she found us… :person_facepalming:

BTW, the GITD I bought when started this BUDGET hobby ( :person_facepalming: ) lasts glowing about 8 hours, sometimes more (I just notice it if I sleep more time and wake up and see the lights in my bed table), after the last light has been shine onto it!

The seller had a similar image in the page, advertising it!

My wife dragged me to the play just a couple of months after I finished chemotherapy (no radiation). It’s sad, but a great play.

:open_mouth: … Good eye!! :+1:

These claim the same. But they at least provide numbers:

Well, TBH, I saw her sig line too, but I refuse to judge people based on their sig line. Her post didn’t look like SPAM to me. :wink:
