Elemental electrical question time again.... amperage

[Turbogus]

Hi gang, I've been running H4 headlight shells in my Jeep and my van for a few decades now but with the intrusion of substandard parts filling the inventory of the auto parts places in my area I'm taking steps to address a problem I've been having. When I intorduced these headlight shells to my rigs I also updated the wiring from in some cases 16 gauge to 10 gauge with relays (one for each headlamp) and new sockets. A problem in recent years is when running higher watttage Wagner H4's (145/100) they would only last about 8-12 months. I've seen the argument the bulb that burns brightest burns half as long but I'm not fully convinced this is the reason for my issue.
With this in mind I just received a pair of Flösser H4's in the hopes that German engineering may be better than China and this may be the issue.
So, at 12V 145W I'm trying to wrap my head around how many amps I'd be pulling. Any ideas?

I sent a bilingual email to Flösser but hoping to resolve this question soonest.

Thanks in advance anda lift of the lynch lid.
Gus

Thanks loads Tinhorn, I knew it was a simple formula, it was just escaping me.
