I have done several readings on my lights and i feel that the number are coming in low. But its interesting to see how mych light is coming uot off my lights.
1000 lumen now is realy bright:).
If anyone want my numbers i can wright it upp but i dont know if it helps. TA_s fix will make them wrong…or nott?
Right now the TA lumen tube is reading too high, so we take the numbers from the meter (usually after 30 seconds when using higher levels) and multiply by .7 to get true lumens.
TA is making a little disc that we add to our tubes to make them read about 30% lower. This means we don’t have to do any math. The reading on the meter will be the correct lumen output.
Correct, for the 3” tubes it will just be a matter of popping them into the meter hole in the correct orientation.
For the 4” tubes they will need to tape the discs to the meter in order to make them stay put. Not hard, just needs a strip of normal official tape to goa round the outside edge of the meter / discs.
All readings are at 30 sec and batterys is 30q att 4,18-4,19v rested about 1 hour after charging.
26650 Battery Liitokala blue. Correction factor 0.68 The factor is after tested light from Maukka.
It was one number that fell outside of the ,68 factor but for consistent reading all are ,68.

I was a bit disappointed in the Convoy L6. I thought they were closer to 3400-3500 like the S70s. My L6 is way too modded to get factory readings from. I think the L6 amp draw was 4.5A and the S70 was 5A so not too far apart.
Bypassing the sense resistor on the L6 got me 7.7A. That wakes it up. Lol
I thought your Astrolux C8 was awfully bright at 1380, then I see they use a FET driver in it. That explains it. It might even be higher than the rated spec of 1300 lumen.
What is up with the Sofirn C8A? 1800 lumen! That must be due to the low Vf of the xpl-2 combined with a FET driver. That’s my kind of C8. It is also conservatively rated at 1747 lumen. I might need to get one of those.
The light I am using only changes by about 2-3 lumens from 5 seconds to 30 seconds so I generally take the readings somewhere in that time frame. At this point it is just verification on all the other spheres.
For my personal readings, I rarely use 30 second readings unless requested for various reasons I have explained before.
Basically when taking many readings throughout the day it becomes very time consuming to use 30 second readings. The batteries also need to be recharged after each 30 second reading in many cases. The light also has to cool off after each reading.
So generally my readings are between 5-10 seconds or when the readings stabilize and then I round down from there to get around 30 second numbers.
I’m sure he’s using the exact instructions Maukka gave him to use (including battery or power supply voltage) to match the readings he recorded in his sphere. So that should all be good. No worries in that department. :+1:
Yes, he gave me both the turn on numbers along with the 30 second numbers. Luckily the low modes of the S2+ are very consistent so the timing is not super important but I did indeed test it at the 30 second mark a few times to double check.
The BLF348 is amazingly consistent, it is what it is and stays that way.
Some of us may have two correction factors. My personal one will be .73 based on all collected data, but can use .70 in the future when comparing community readings. I'm not sure I will want to add any filters to mine - as it just adds another variable. I think I'm content with mine the way it is.
That’s cool, I would just recommend that if you say you measured the lumens using Texas Aces Lumen tube to please add what correction factor you’re using so that other people won’t be confused.
Did i tell you guys i got almost 19000 lumen @30 seconds with my mt09r TA triple xhp70.2… This light is amazing… i think its one of my best xhp70.2 light…
