ISEN-ASTC-L is a service of the Association of Science-Technology Centers
Incorporated, a worldwide network of science museums and related institutions.

Hi everyone,
We're prototyping a phosphorescent vinyl activity here and have had
pretty spectacular results using "Streamlight Stylus" blue LED
penlights.
We're a little worried about whether these are actually suitable for
unsupervised (or lightly supervised) use on the floor, though:
they're really, really bright. They're labeled "Class 2 LED product
/ Avoid direct eye exposure" on the package, which sounds fairly
ominous in terms of kid safety.
Is anyone aware of any guidelines for handheld flashlight brightness
on the museum floor? Fairly extensive Googling hasn't turned up much.
Thanks!
