26650 lights that can maintain 1500-2000 lumens?

Zebralights do maintain brightness after stepping down but the stepped down levels are much lower than the rated turbo output, which is typical of all flashlights. Only Olight and Fenix spec their runtimes with honest step downs on their websites and honest ANSI 30s output levels. Zebralight like Acebeam and many others exaggerate their output 20% or more above actual output.

I have never known Zebralight to exaggerate output. Generally, they are accurate with output to 2 decimal places, but this is assumes they have tested the light, which is ordinary for them to do. Looking at the SC700d product page it is pretty clear they didn’t test it yet. Also, every Zebralight product page for any flashlight that steps down indicates that it steps down. The SC700d doesn’t indicate any stepping down, which is what threw me off. Even the brightness testing curve you posted above doesn’t appear to indicate any stepping down… just rapid drop off from maximum brightness to 1000Lm, and there it appears the current regulation kicks in. That chart squeezes a lot of time in the horizontal axis, so maybe there is a tiny bit of regulation at 2500Lm, followed by an intentional step down, but it is odd that there is no mention of it on the product page.

Here’s an example. Per Maukka’s review of the H600Fc Mk4, (1124 lumens measured @30s vs. 1568 advertised). Maukka is one of the most reputable member here with a super expensive, validated integrated sphere. But keep in mind Zebralight is not the only one. Almost all of the manufacturer’s lumen ratings are 15–25 higher than actual as if it’s the industry standard. Only Fenix and Olight lumen specs are accurate and sometimes even conservative.
