Surefire eb1 models help

Anybody know what numbers to look for to tell a 200 lumen from a 300 lumen Backup?

I hope you enjoy your stay, Marins!

I had to goggle it because I had no idea what that was. Funny thing is half the entries were for “EB1” and the other half were for “E1B”.

Anyhoo didn’t find anything pointing out any differences.
