Thanks for the test.
This confirms what I suspected using wonky comparisons between Clemence (B35A) and Djozz (FC40) tests, the B35A is a superior LED vs the FC40 at low to moderate~high power that we find in EDC lights.
6W nominal :
B35AM 1A : 740lm , 130lm/W
FC40 0.5A : 610lm : 113lm/W
12W nominal :
B35AM 2A : 1335lm , 113lm/W
FC40 1A : 1100lm : 98lm/W
18W nominal:
B35AM 3A : 1850lm, 102lm/W,
FC40 1.5A : 1700lm, 99lm/W (higher than at 1A, reading the exact values on the graphs is hard)
24W nominal :
B35AM 4A : 2270lm, 92lm/W
FC40 2A : 2200lm, 94lm/W
The B35A is measured about 1000K higher than the FC40 (6300K) but at these high CTTs it shouldn’t matter much, maybe a couple of % of efficacy.
So it has higher to equal efficacy up to 18W while being less floody and having better duv in general, especially at low CCT where the FC40 of often yellowish whereas the B35A goes under the BBL.
If only it had a thermal pad it would be perfect.
