I'm a "newbie" member of CPF. I look forward to sharing info with other members.

Here's my question:

I recently purchased a Olight T20 R5 2010 version light that was advertised as having 310 lumens max. output.

The factory packaging indicate it's the 2010 version, however the packaging shows 270 lumens at max.

Is there any way looking at the light to tell if it is the 310 lumens output or the 270 lumens output version?

THANKS in advance for your help!
