In testing I was barely able to see any difference between Turbo and High. From memory I measured just over 10% difference in output but that was with the proto led.
High should be 2 amps at the led and turbo 2.5 amps.
Here is MRsDNF runtime chart for 4 30Q from post #4 of the main GT thread. You can see that at 2.5A your run times suffer quite a bit (blue line). At 2A the runtimes are much better (red line). So for short usage where you need max output turbo makes sense, but for long runtimes (at almost the same output) it’s better to use 2A.
If you look at that 160 line (roughly when output starts to drop) the 2.5A reaches it in 35 minutes. The 2A reaches it in 55 minutes. At the 2A setting you get a 57% boost in run time for a tiny bit less output! I think it’s for this very reason that NarsilM v1.2 was designed to have the ramp stop short of max. (Correct me if I’m wrong)
So 2A is definitely the mode to run for practical purposes and longer run times. The 2.5A is there for max output and distance even though it drains the batteries way faster.
From high 2,0A (2490lm) to turbo 2,5A (2630lm) there is only a higher output of 5,62, so 7 are not bad ;).
Or from 1,9A (about 2440lm) to 2,5A about 7,7% in your case.
If I will get open the GT, a TLF colleague will programm the driver with ramping to 100% output (2,5A) and also put a XHP35 Hi E2 3C 5000K on it.
Ramping to 100% is good for me, because I want to use ramping and I don´t like the short flicker if I will change to turbo with double click.
I know this short break (light off) is necessary, if you don´t want to flash the light in turbo for a short time, if you will use the battery level indicator or the electronical lockout.
New binning is E2 instead of D4.
Amps will be same at 2,5A.
Binning D4 is about 550lm at 85°C at 350mA and about 4,8 times more at 2500mA (2630lm, Test Texas_Ace).
I know that calculated lumen are most not correct, but I hope, that with Binning E2 I can get:
Binning E2 about 590lm at 85°C at 350mA and about 4,8 times more at 2500mA, so about 2850lm, so about 8% more lumen output and perhaps 8% more range.
I don´t have know how and equipment for flashing drivers, so I removed driver and switch board and will send it to a colleague.
Driver will be reflashed with NarsilM, but with changing Ramping up to 100% (2,5A).
LEDs on switch board will be changed to blue or orange, or complete switchboard will be changed.
I’m not sure who to send this to so please excuse me ,To anyone that could help me Thank You
I haven’t heard anything about my BLF GT w/batteries starting to get a little concerned at this point if it will ever show up, could someone please let me know what’s going on ,Thank You I think I was # 975 I paid for it on 12-10-2017,Thank You I’m not sure if this is the right Neal to contact.
Any Help would be greatly appreciated…
Check post #1 of the GT thread. The last orders (about 50 lights) should be picked up by the shippers today. Sometime after that Neal will get the tracking numbers and send them out to the customers. That’s the latest news I’ve heard.
