Looking for a zoomie, got questions

I’m collecting kcd numbers to 1504, B158 and Z1. All domed emitters below have been dedomed

It’s hard to find Z1 numbers with dedomed XP-L/XM-L2. Even with XP-G2. I may add something to the list later. I skipped “something must be wrong” numbers that I found. I skipped the numbers where I knew there was a collar too, but left SoH which likely has one. Anyway, with the only emitter where I have semi-direct comparison, 1504 roughly doubles Z1’s beam intensity…
1504 numbers are indeed all over the place.

Was there something with 1504 quality dropping over time? I’m still reading on this topic, but I see many comments from owners satisfied with this light.

I’m wondering about dedomed XHP50.2….if it does 190 kcd in Z1, it should do 300 in 1504 with 2000+ OTF lm. scianiac, could you tell us more about this result? Did it involve a lot of black magic that you use normally or just regular well-known stuff? Was it with a collar? Direct drive with a pair of high-current batteries?
From what I’ve seen, dedomed XHP50.2 should have very roughly half cd/lm of XP-L HI, which suggests that you have driven it really hard and / or used some good tricks.
