7-8A is about right for xp-g3 triple on A6 driver. Shorter, heavier wires and a real good high drain battery, will bump it to the higher end of that range.

Some fet drivers will do better than others, depending on the specific fet used, and trace specs of the board.

Same here, about 7.6A, same leds, same driver as Blazer… Samsung 30Q cell.

Well, sorta……

I am running a H17F driver, and LG HE2, but they will all be pretty close.
I prefer the double tap for “turbo”, and regulated for my normal low – high modes.

HE2 vs the 30Q is a wash.

triple XPG3 should pull like 12-14A from a good IMR cell

if you dont use a clamp meter you wont get accurate readings as you add a voltage drop to the circuit

This triple for me with…
…Wights FET (no AMC7135) ca. 5-6A (FET PSMN0R9-25YLC)
…TA 17mm ca 7.2A (PSMN0R9-30YLD) <- wrong FET, I used PSMN3R0-30YLD (sorry for typo)

I never had the actual BLF A6 driver, but these are somewhat comparable.

edited for wrong FET

Astrolux drivers from BG have big variance in actual tested current. I dont like testing current on flashlights, but when Im building pill or drop-in I test it with small 5A current supply. It have too big internal resistance and current is 2-3 times lower than with good imr cell, but anyway it is suitable to compare same leds with driver builds. LEDs are very close nowadays, while astrolux drivers can give 20-30% difference to each other.

I get about 11-12A with H17F with XP-L HI. It’s brighter than a few quads that I have.

The higher measurement is probably the more accurate one but – as said already – you should use a clampmeter for easy and accurate measurements with flashlights at higher currents.

I get 12.20 Amps on BLF A6 (A17DD_L) driver, with 3 x Osram Oslon Square CQAR.CC (3500 K 96 CRI) and LG HE4 @ 4.18 V, measured with UT210E.
But this means also that the temp of the FET after 30 sek. on Turbo raises above 100 deg C which might be not good for it’s lifetime… Sad

My LED tests: in German (list here) ---- in BLF: Luxeon MZ 5700 K (90 CRI, 3 V) - XP-L2 (includes High CRI variant) - XHP35 HI - XHP70.2 - SYNIOS DMLQ31.SG - CXA1304 COB - unknown 5050 LED - more tests + translations coming soon!

Getting around 10amps on my S8 triple with 219c and fet+1. Measured using an inline power meter.

S8 Triple - 219c, MTN-17DDm
M1 - XP-L 7a, 105c
C8 - XP-L HI, A17DD-L
