My measurements from TA lumen tube and Opple III/Pro, of a different JKK model but shows the excellent current limit of the Nealsgadgets battery. Capacity only 2800 mAh though. HERE:
NIGHTWATCH CHAOS
Output:
Nealsgadgets “Mystery” Lishen “LR2170HP”: 29300 lm.
Samsung 30T 25800
Samsung 40T 22900
Molicel P42a 22600
Convoy Liitokala 19300
Wurkkos 5000 mAh 18800
Other numbers:
Ra 67
CCT 5808 Turbo, 5736 Turbo-1, 5529 Turbo-2, 5507 T-3, 5479 T-4
Duv 0.0047 Turbo, 0.0064 Turbo-1, 0.0093 Turbo-2, 0.0097 T-3, 0.0100 T-4
CCT increases and Duv decrease with higher output.
Of note Nightwatch Chaos comes with green-reflection AR lens, which surely helps with the tint.
