How much do health globes heal

So far, I have seen two different types of health globe, each healing a different amount. The percentage healed is not fixed either. It differs slightly from globe to globe.

• Small: Heals for about 18-20%. Dropped by normal monsters mostly.
• Large: Heals for about 33-35%. Dropped by champions and uniques mostly.

I have yet seen anything bigger than a large.

Note that I had no bonus to the amount healed by globes at the time of testing, so these figures should be very close to the real figures.

As of the end of the beta, they healed 15% of your max health. I assume it hasn't changed at this point.

While an older source, the Diablowiki site has some good references from development plans for health orbs.

The intent was to have a variety of different strength orbs in game, ranging from 15% to a rumored 100% (the following was on the official Diablo 3 website before they took down the game guide for revamping):

More powerful health globes, capable of completely restoring your health even at death's door, might exist somewhere in the world of Sanctuary. Of course, that's probably wishful thinking.

During a demonstration of the still-in-development PvP Arena system during Blizzcon 2010, the health globes that spawned provided a 40% heal.

In addition to the variable strength of the orbs, there are item modifiers that provide a direct increase of the amount healed. The amount provided varies widely, and scales with item level.

Some examples I have seen are a level 10 rare item that provided +40 life from health globes, a level 8 rare item that provided +28 life from health globes, and a normal level 10 magic item that provided +17 health from health globes.
