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!
