Hello everybody, it’s been a long time for me…Cheers to anyone that’s still around! Was like i made a break of 9 years. I still have 40 flashlights on my collection, used to have triple of them in numbers, all cherry picked. So, suddenly, i felt like my flashlights are outdated! Did a search, honestly, i do not like all that technology around in flashlight and useless performance and runtime. I still think that plain and simple flashlights with usable runtimes are the best.
So, i decided to mod my flashlights with everything latest is around. Bought most leds from KD, but honestly, the results weren’t what i expected, i thought i would get something more.
What leds i got in enought numbers:
LH351D W6 cri90
XP-L Hi V3
XP-L HD W2
What i modded until now and the otf results(Still have to mod about 30 flashlights, the big one guys !):
quark 2xAA tactical: was 190lm with xp-g r5, now 234lm with xp-l hi v3 (a bit low)
Fenix E40 4xAA, (0,96amp on the led): was 220 with xp-e2 r4 and now 340lm with sst20 L5. (Thats a low bump?)
Fenix PD32 1x 18650 (1,2amp on the led) : was 325lm with xp-g S2, 1st mod 355lm with xp-g2 R5 and now 390lm with sst20 L5. (was expecting something more)
Fenix Tk15 1x18650 1,46amp on the led): Was 380 with xp-g s2, 1st mod 417lm with xp-g2 S2 and now 470 lm with sst20 L5. (Still here expecting something more)
nitecore ife2, was 260lm with xp-g r5, now ld531d w6 and 360lm. (expecting something more too here)
Farka xenoled f8, one of the beloved, works with 6χ7135 ~2,2amp output 800lm with a sst40 N5. (thats possibly a good result)
Armytek predator V2, was with xp-g2 R5 and 2,1amp at the led, modded it with sft40 and i get 714lm. (possibly ok due to throwy i dont get an accurate reading?)
olight S35,was 380lm with xm-l, and now 400lm with xp-l hd w2. ( don’t like that)
18650 host, modded with 7x7135 2,46amp, no old results, now 870lm with sst40 N5(thats good).
olight s10, was 350lm με xm-l, now 340lm with sst20 l5. (too low i think)
Nitecore Ea4, i get about 860lm with lh531d w6, did not measure it before the mod.(was expecting something more)
Trustfire X7 thrower, was getting 1080lm with xm-l2 u2 and 4.5 amp driver, now i get 2160lm with xhp50.3 hi and 6V 4.5amp(stated) KD driver.(Thats possibly the most logical result, as i guess it gives less than 4.5amp to the led, have to measure it)
In general and this is where i need your help. I like the performance of sst40 N5 and xhp50.3 I doubt somehow the performance of xp-l hi and LH351D. I find poor the performance of sst20 L5 and xp-l hd W2. They seem low, according to the datasheets, i should had seen a higher lumen bump. Do you think this is logical?
Is there any chance KD does not put the stated bin? SST20 was like L2 and xp-l hd was like v3 or less? LH351D also, was expecting something more. At these amp, i should have been getting around like double the efficiency. The tint was ok in all conditions, as expected.
Thank you for your help nice to see you again!
