I saw a couple of reviews of those H4 LED replacement "globes". While I'm eagerly anticipating that particularly technology, it's nowhere near up to scratch yet - you'd be better off with a box of matches and have someone sitting on the bonnet lighting them one after another as you drive along.
I'm back on standard globes myself as both IPF Fatboys have blown now - they put out a good amount of light, but cost way more than they should have. I might try Philips or Narva extra-bright globes next and see what happens.
