The new light looks like a good upgrade, though I think my original PD22 with the XP-G2 emitter may serve my needs better. The lower 3 lumen low is the brightest I'm comfortable using when my son is sleeping next to me in the tent. I use the 105 lumen mode on my PD22 as a backup headlight on my bicycle. While the ability to use RCR123 batteries would be nice, I get better cold weather performance with primary CR123a batteries. I have a ton of Panasonic CR123a batteries that I bought for $0.75 each recently, so I'm not in a hurry to start using RCR123 batteries.
