It's hard to say.Just out of curiosity, which light would you prefer out of the extreme and the 120P? Is the extreme good enough to knock the 120p off its throne?
For low mode use, I definitely prefer the much lower low modes of the 120P, and I like the smoother transition of spot to spill that the SSC emitter provides. But I find the spill of the 120P to be a little dim, requiring me to go up to higher output levels to illuminate a wider area. But if I had to choose between the two for low mode night-time use, the 120P would win. But truth be told, I keep finding myself gravitating back to my NDI for low mode use for its good balance of spot/spill brightness.
The Extreme is of course a lot brighter and throwier on hi, which is great for that use. It is also more efficient on max (I typically don't run my 120P higher than 85 lumens, because I find the trade-off in battery runtime isn't worth it). With its excellent throw and brighter spill, I prefer the Extreme for cases where a lot of light is desired. But here I'm more likely to grab my Jet-II IBS, due to its even better throw.
In other words, I have yet to find one light that does everything.
Oh, and I've just added the ramping graph to the main post. As you can see, its not too different from the NDI (just ~1 sec faster on RCR):
