First, :welcome:
Let's see, there are some things to consider. Output & runtime. I'll assume you want a simple to use push on light without all the fancy low modes and blinking modes from your description of use.
Perhaps the best thing would be simply to upgrade your G2Z. That way you keep the light you know. Instead of running the stuck bulb you use a high quality LED assembly, also known as a
Malkoff Drop-in.
The only thing holding back a 100% recommendation for one is the heat problem. LEDs need heatsinking and the Plastic body of the G2Z doesn't provide that. So here's what I'd consider doing:
Malkoff Drop-ins come in all sorts of "flavors." So instead of getting the high powered ones get a medium powered one; an M60L. It'll still be brighter than your stock incandescant G2Z with far better runtime.
Also to help with the heat I'd consider getting a Surefire aluminum "head" and replace the stock plastic one. That way the LED can at least have some thermal path to outside air.
There are other possibilities, but this would be likely be my first choice based upon the information you gave.
The big question is how bright do you need the light to be? Are you thinking of going over to LED because of brightness or because of runtime? Or for better durability? So, after qualty and reliability what's most important?
Many of us here are glad to help so please tell us more about your needs.

edit: I am relatively sure that a Malkoff dropin will work in a G2Z however I don't have one myself, so we'll need an affirmative from another member who has tested it to be 100% sure they are compatible.
If not we you can always buy a Surefire C2, which will be very similar to the G2 iirc and use that with a Malkoff dropin... including the high powered ones.
