Thank you!
That’s why we are here.
The lumens have been tested at startup - but based on Post #929 the decrease is continuously, so the difference between 0s and 30s can be neglected…
Actually it seems like I am the first one who tested a GB-version. My test of the retail-version is very similar to another one sold in Germany and also near to the values Terry measured for the prototype.
Regarding my general measurements I compared it inside the TLF and they are in general in the area of others - so it seems to be on the same level. Also the values I receive for other flashlights are on the level of what others measure with there Ullbricht sphere. My Luxmeter seemed to work quite well - another point why I am actually quite upset…
Actually they only have CW in retail - the CCT of the GB-version is not indicated. But especially for you I murdered my strict “no wall-shots”-policy:
From my point of view the GB must be the one with 5.000 K
As written above, the GB70 I have in hands seems to be the 5.000K - and as written it gives a good 6% more power than my 6.000 K. But from my point of view 17 klm are far away - see the comparison with the DT70
Another point discussed was the difference between the GB35 (4.500 lm) and the TM28 (6.000 lm). From my point of view, it can be explained best with the wallshot (again!). While the MT09R35 give its power to the Spot, the TM28 has a bigger and more powerfull Spill, together with a bigger Spot:
… its hard to show it with a photo…
