Surefire L1-How do you tell the different generations apart?

Hi everyone, I was just wondering if there was a certain way to tell the different generations of the SF L1 apart by either looking at just the light itself or by looking at the packaging? Also how many generations are there currently? Is 3 correct?

Thanks in advance.

Thanks for your help Wicho and thanks for the link thermal guy, that was a good thread to check out.

As far as the newer packaging, I've seen some that say "New higher output more runtime" in yellow and black located just to the right of the L1 on the package. I'm guessing that this is the latest one released?
