So as mentioned this is my review with this little monster:
Firstly comparing with ordinary GID toys:
search
the Embrite glowing because it absorbed the light all day as I opened it in the morning and left it be on the desk.
Then I use UV flash light to develop more strong and intense of absorbing.

and then I turn the light off.
(sorry for low quality image due to the fewer light and I don't have any tripod with me at that time)

Well the capsule shine so bright and even brighter than the toys (in fact I used UV flash light only 3 secs.)
and when the light is on it still glow which very satisfied me. So this is very useful for your EDC such as attach it to something you always want to find when you were in the dark situation and don't want to turn the light on (ie. don't won't to wake someone up)
