Scotty,
H1, H3, H4, etc are different globe configurations. You will need to understand which configuration your lights have so that you can order the proper globe type (and I'm not at all sure that Lightforce follow these, anyway) but it would be a lot less difficult for forumites to explain the differences if you had pictures (I can't get them to work where I am at the moment).
H4 is the normal set-up for high/low beam headlight globes. My old Cibie Super Oscars used H1 globes (with quite a long overall length) and my Hella worklights use H3's, which are substantially shorter overall, even for the same wattage.
Perhaps you could simply try Google or Wikipedia - I'm sure there's going to be something there that will help you gain a better appreciation of the differences. Maybe "H1 Halogen globes" or "H3 Halogen globes" might be a starting point.
Otherwise, if you wander down to your local Repco/Supercheap/even fuel outlet, you may be able to see the differences in the flesh, so to speak.
Regards,
Charlie
