Alternator 'spits it' with driving lights on! Also, anyone used SUPER LOOM?

Howdy campers.

Just finished hooking up some second hand (barely used) Cibie Super Oscars to the old 'Betsy' Tojo 60 series. Used the Ziel wiring kit, made up some stabiliser brackets & installed a LED switch for effect. So, I was quite happy 2 hit the 'frog & toad', test em out & not have 2 rely on the 'using the FORCE' to navigate on those windy slow roads (even with the new H4 inserts, the main beam is pretty ho hum).

So, on a couple of hour long drives, those impressive 100watt Cibie's (certainly seem a good unit!) took their toll on the alternator & started to drain the batteries! Buguar. So, the question is whether the alternator's stuffed ( can u get it reconditioned? ) or whether the 30/40 amps or so that its rated to just doesnt cut it & therefore i need an upgrade. Has anyone else had similar experiences?? replaced/ reco'd an alternator from a 60 series? Any recomendations gang?

Also, considering the PYRANHA SUPER LOOM for the headlights. they brag 25% increase in power which for the winter driving i do would be beaut. Anyone tried it? does it get that much increase? Minimal voltage drop? price?

alrighty, cheers guys & I look forward to any feedback.
