here is an eneloop runtime chart for the D3AA
here is a link to the source of that chart, it has additional outputs on Eneloop…
here is another source of D3AA data on Eneloop
I do not have a runtime link for the Zebra SC54c N, it should be longer than the H53Fc N data from this review
The Zebra has much longer runtime than the D3AA, below 10 lumens… thats the Zebra Advantage… the ridiculously long runtimes at low outputs.
The D3AA has much lower Flicker Index than the latest AA Zebra… that was unexpected.
(these are my own Opple 3 measurements)
Notice how flat the lux line is for the D3AA, compared to how much the Lux on the SC54c N is oscillating up and down…
here are some of the other SC54c N Flicker Index results:
notice only one output has a straight line for the Lux output, all the other modes are modulating the Lux up and down… which produces a less desireable Flicker Index score…
The H53Fc N from both 2023 and 2024 have very nice constant lux, like the D3AA. The SC54c N otoh, uses more flicker than any of those.
The 53 series driver has more constant power to the LED, and lower Flicker Index than the 54 series driver
there are tradeoffs:
The AA Zebras definitely has great form factor, and runtime… otoh, the choice of LEDs in the D3AA is far superior. And the D3AA offers a floody beam that is very evenly diffused.
otoh, the Zebra SC54c N beam and Tint is embarrasing, with a greenish yellow corona, and a shadow ring in the spill:
here is the stock D3AA beam by comparison:
