R5 vs S2?

My most recent light is a 4Sevens Preon 2 S2 penlight. I noticed that 4Sevens changed it's ratings to 120 ANSI Lumens instead of 160 Lumens OTF. I'm curious, as I've heard both sides, whether this is because 4Sevens switched to ANSI standards for their advertising or if it's because the S2 sacrifices brightness for longer runtimes. It seems odd that they would sacrifice 40lm in most of their line, at least to me, but I'm not sure so I figured I'd ask the experts here. Which is it? Is the S2 as bright as an R5?
