What is the general life expectacy of a ROP bulb?

[jhMadCow]

I plan on running a high bulb on 6cells (7.2 volts). How much life would I get out of the bulb? I'm wondering this because I'm about to buy parts for a ROP mag and I need to know if I should buy 2 packs of the lights or just go with one pack.

I pop mine pretty fast...about one per two or three months with medium use.

See that is what troubles me. I don't want to have to keep buying bulbs for this thing. I would much rather just pay a little more for an LED light. Thanks for that Beer
