Yes - less intensity. I have an SFH55 from Neal, just got it yesterday. Planning on swapping it in to a WT90 in place of the SBT90.2. Check out Dave's thread here: https://budgetlightforum.com/t/-/67698. He's got the chart of various in the OP, my post here: https://budgetlightforum.com/t/-/67698/49
We don't think the chart is accurate in all respects, but a lot of it seems to be.
The issue with the K80 SFH55 is if it truly can pull the amps, it should be over 30 and that's not great on any single cell. That's why the bigger WT90 triple 21700's is right now about as good as it gets. Was thinking of a GT90 too, 8 18650's should do ok also.
Interesting if the WT90 with one SFH55 would do as good as the triple SBT90.2 HL HK90. Or put three in a HK90 and get >30K lumens? Interesting...
