Wow, that’s lower than my expectation. Since the Turbo is driven by pure FET and thus can vary greatly due to numerous reason, maybe we should take the max regulated brightness (7x7135) as a base. On my ROT66, the peak output is 5050 / 715 = ~700% if compared with the stabilized 7x7135 brightness. Or 5050 / 740 = ~680% if compared with 7x7135 at 0s.
30Q's should get lower results than VTC6's, but not that much lower based on my Q8 tests - this is 17.4% lower than Fireflies integrating sphere results. So something is off, or the lights tested are different, or little of both.
On 7x7135 mine is 710 at 0 sec. So peak is 609% (6.09*710=~4325).
I suppose you mean 609%, right? My 7x7135 was close to 730 740 at 0s, and it stabilized at 715 after an hour. My numbers are probably on the higher side, however the peak to 7x7135 ratio seems not as high as expected on your sample 
Of course, typo.
After several tests with cooling the light in between the most I got at 0 sec was 4413 lm. The 4325 lm is an average out of three. Using VTC5A didn’t make any real difference, 4440 lm on average with a max of 4500.
What is the actual lumen number you got on the max regulated with your integrating sphere?
So that’s ~630% of 7x7135 at 0s. With 3 x NCR18650GA cells, I got ~4650 at 0s, which is ~630% of 7x7135 at 0s. With VTC6’s, that ratio is ~680% (5050 / 740).
Some white wall beamshots from TIR lights.
The ROT66 will be great for night photography in a US ghost town.
Wonder what a minus pink filter would do for it in terms of subjective and objective differences? Of if the AR coated lens has a tint that’s green/magenta that also slightly affects tint?
My calibrated TA tube measurement for Nichia 219b version is
4740lm @ 0 sec, 4300lm 30 sec. with VTC6 4.2V
Similar test result with either VTC5A or GA.
I took time redo calibration for my TA tube. Now, my 219B ROT66 with 30Q’s measures 4440 lumen at 0 second, 3910 lumen at 30 seconds.
I just want to say that Jacky of Enogear/Fireflies did just reply to my email and sent me my replacement Enogear AA stainless steel and sent me a free stainless steel 14500 usb rechargeable light. Therefore I will definitely buy more of the ROT66 soon. 
Finished my review:
Can I send my DOA XP-L back?
Yes, 2 year warranty, please email us
ROT66 Aux led board available now
The MF01 219C v1 (6 wires) is more one the rosy side than the MF01 219C v2 (2 wires) that is more on the yellow/green side. If I remember well, charles lin’s MF01 is a v1, both of yours are probably v2.
If the aux led board was offered with more emitter color choices, it would be a certain hit. Many people didn’t like that Emisar only offered the cyan ones. This would have been a opportunity to set your stuff apart.
Yes please, amber secondary would be much more useful than blue.
Fireflies, can you post some photos of the board itself and installation procedure? Does the firmware of older lights support it properly?
