Howdy Workgeek50, and welcome to CPF,
Gee, that's a mighty good friend you have there. Here is a link to the official site:
http://www.surefire.com/g2x-pro.html

I don't own any Surefire lights, but their reputation is for extreme excellence in flashlight manufacturing, and I'm sure the G2 is no different. Of course it's different from many lights with it's polymer body construction. It uses 2 of the less common CR123 batteries, which can be somewhat expensive if bought at brick and mortar stores (up to $8-10 a piece!), but can be found on-line for a dollar or two a piece:

If you just use the light occasionally, say for a tool box or in the car, buying batteries (on-line) is probably the best way to go. If, however, you find that you use it all the time, then it might be in your best interest to consider some type of rechargeable cell:

You can learn a lot about batteries here:

For further information, learn how to use the Google Search box located at the top left of most CPF pages. Leave it checked for "CPF Only", and it will limit it's search to relevant threads found on CPF. For instance, simply type in "Surefire G2" and you will get pages and pages of results.

And, before buying batteries or chargers, be sure and visit the "Flashlight Electronics, Batteries Included" section of CPF. Lots of good info there:

In any case, that's just to get you started. I'm sure some Surefire aficionados will chime in soon with lots of good information for you.

Have fun!

There are two G2 LED's to concern yourself with, the older G2 LED, that uses a P60 swappable lamp assembly and has either a polymer head (older) or aluminum head (newer). The newer version which is the G2x uses a one piece aluminum head assembly that you can't change lamps on. The originals with the P60L were kind of ho-hum lights, mostly because the P60L was a bit... well it kind of sucked. On the plus side there are TONS of high quality LED dropin's that you can replace the P60L with, if you have a polymer head stick to the lower output modules or multimodes and don't run it at full blast for more than a few minutes. If you have the aluminum headed G2, then you can pretty much use anything but the highest power 700+ lumen LED dropins.

I believe the older G2 LED used the P60L lamp assembly. It was rated at 80 lumens. The newer G2 LED used the KX4 head, which was rated at 120 lumens. You could tell the difference between the two as the newer one has KX4 written on the head, and the head itself is enclosed, with no swappable lamp assembly, and the older one had the swappable p60L lamp assembly. The older P60L was known for cooking itself to death over time, hence the upgrade in design to the KX4 head. It would not surprise me if the older version was available with both nitrolon and aluminium bezels.
