Convoy S2+ afterglow

I just got my first Convoy S2+. After I turn it off, there remains a faint green glow around the top edge of the reflector. It lasts for maybe a minute or two before fading, and it remains even if I take the head off of the light - it’s clearly not drawing anything new from the battery.

It’s too faint to notice in daylight. And I see no light coming off of the LED, just from around the top edge of the reflector, next to the lens.

Is this common? Is it something I should be worried about?

Mine does the same!. O ring GITD!.

Not concerned one bit because it looks neat!.

It’s a glow in the dark o ring around the lens in case you didn’t know

Gotcha. Thanks for the explanation!
