 Philip:

Yes as stated the reference article, after a period of time voltage will fall for both types of batteries. Still at full charge the higher voltage batteries will induce more current to flow through the LED's. More current will result in more light.

As for the long term performance of the two different types of batteries, and which one will create more total light ( lumen hours) you need to look the total power available from the two batteries.

My apologies for not making this clear in my initial post.
