I just did a thread about the same thing not long ago, might be to some help.

Red LED drivers

Hi I’m trying to find a suitable driver for a red XP-E for use with a single Li-Ion. Since the forward voltage on these are very low (~2.4V) the regular constant current AMC drivers seems like a bad choice. Anyone that got something to recommend? Single mode or high/low mode drivers would be prefered. This driver seems almost perfect if it would work https://www.fasttech.com/products/1114501 This is also interesting https://www.fasttech.com/products/1105800
