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…
Wow, I was thinking if TA measured it before at let’s say 21,000 lm, then it might turn out to actually be closer to 15,000 lm once he uses a .68 or .70 correction factor. But your still seeing 19,000? That’s huge.
