The VTC5A are giving me a good 550 lumens more than my VTC6, I'd love to know if this takes throw up to 1500m!
Tested the TN40vn tonight with VTC5A and got 11,230 lumens turn on! Dropping to 10,040 ANSI.
VTC6 managed 10,570 turn on and 9,500 ANSI.
At 3.90v the VCT5A's was managing 10,230 turn on and 9,170 ANSI.
The poor X45vn voltage to lumen performance made me question whether the TN40vn could keep the pace but it gave a solid performance.
As for heat, at 4.10v the TN40vn dropped 1,300 lumens after being on 1.30 minutes past ANSI. So turn on 10,700, after 30 secs 9,900 and 2 mins 8,600. Pretty decent given my DT70 drops 1,500 lumens in 30 secs and the X45vn 3,000!
