What did you mod today?

If there is a demand for it I can do it but each led is around 20-30 minutes to finish and shipping costs added all things almost triple the led price. I don’t think anybody will pay that much. If there is a significant demand I can make them.

And almost forgot:
Made another C8+ and an Eagle eye X6 with Osram White flat 1mm2

Did some simple work on a friends Q8, put 4 SST-40’s on a LED4Power quad board made for the Q8, swapped out the MOSFET for a 404, opened up the reflector aperture’s to fit over the entire substrate of the 40’s, replaced the springs with stacked Blue springs… the Q8 now has a nice defined hot spot and does 11,200+ lumens at start on new 30Q’s. :wink:

Dale - is that a typo? 11200 lumens is 2800 per LED, if I understand that right? SST-40's are good, but...

Still a nice CW mod!

32,600 on my meter Tom, translates to 11,247 lumens. Brand new first time charged 30Q cells. Even if you take off 10% for margin of error, it’s still over 10,000… the numbers are what the numbers are, it’s bright as all get out and Rick will be tickled to death with it.

Edit: Cool white? Not so’s you can tell….

I got 12.5K lumens in a SupFire L1 (5 SST-40's) at turn on (manufacturer lumens), so I know it's close.

And in a modded SP03 with 3 SST-40's I got 7480 lumens at turn on (manufacturer lumens) and 235 kcd, using VTC5D's (Vapcell).

Checking my notes for the SP03, I realize I added in 26 AWG 3" wire to add resistance, not sure bout the springs.

So, sure looks like 2800/LED is realistic for a fully tweaked setup.

Koef3 found in a bare N4 led test 2670 max, and I found in a bare led test around 2500 max for the SST-40 (the heat management of my gear is good but not as good as koef3’s). In a real life flashlight build with 1x18650 I got 2200 lm at startup. The latest bin is N5 so if koef3’s number is taken you can get 2850 lumen max out of a bare N5 led. Reflector and lens will normally eat 15% (also expected for a Q8) so if everything is perfect you can get 9700 lumen OTF from a quad.

These numbers are for a calibration close to maukka’s calibration (=as close to reality as we know it). Perhaps Dale and Tom use a different one?

Yep - numbers I quote are for my original (TomE lumens?), subtract about 12% for ANSI - Dale sent me the maukka cal light kit, then on it went to Richard.

Mine are 6500K N4's from KD -- I did this back in May 2018 or so. Thought I read more neutral tints are becoming available, not sure where though, not sure what temp/bins.

I see KD has N5 binned 6500K's now, oh boy...

Re-reading my notes, best #'s I took with the SP03 (FandyFire/SolarStorm) were 7890 at turn on on fully charged 30Q BT's, 265 kcd. Again for ANSI calibration, it would be 6960, 2320 lumens/LED, but again at turn on. Sorry, no amp readings but it must be totally insane, like ~27ish?

Mouser has listings for N4 bins in 5000K tint (among others) and I posted in the Kaidomain forum hoping they would be able to source some since Mouser does not have them “in stock” for small quantities. We’ll see!

As I said, even if taking the 10% loss that the calibration lights demand, this one is still doing over 10,000 lumens. With Maukka’s calibration lights, according to the S2+, I was about 10% over. Hard to say how it relates going from a 300 lumen small light to a 11,000 Lumens plus big light, but there it is. So, if I astutely applied Maukka’s calibration lights this Q8 makes 10,122.3 lumens. According to what Jos is saying, the calibration lights are still off, so who knows what the real answer is.

Bright as He! There ya go!

Are the SST-40's N4's? 5000Ks? Could you tell us where you got them? I see N4 5000K's listed at Mouser, 500 qty min, and not in stock - the only place I know of.

Maybe Richard is look'n at them - I see he's got the flat whites now, and spacers!

I would love to get some neutral tint SST-40s. :heart_eyes:

Great LED… but the biggest problem about them was we could only get them in cool white and I hate cool white.

Putted one Osram white flat in my Brinyte B158B

You are not allowed to post this without numbers :expressionless:

Last night I got an SST20 4000K 95 CRI Emisar D4. Promptly swapped its star into my modded aluminum-titanium D4.

After testing it and playing around with it, I concluded that the SST20 was considerably inferior to XPL HI for this light, so today I swapped the old star back.

:smiley:
Sorry! Just finished it but I’m at work in night shift. When I get home the sun is up. When I leave home the sun is up too. So I need to wait sunday night because that day I finally staying home.
The dedomed XP-G2 S4 2B done 300kcd what I removed now.

:+1: I can wait till sunday :slight_smile:

Instead, it was my day off today, so I got round to testing a led tint for TA, swapping main led and switch leds in a Sofirn SC31, and just tonight swapping in a Luxeon V led in a small Supfire 16340 light that was modded before with BLF-A6 driver, spring bypass and colour-changing tail. It is now a pocket rocket waiting for that new ultra-high current 16340 cell that Vapcell was trying to source for us.
In the meantime I bought two cheap Enercig 16340 cells from NKON that are rated at “14A” on the website. I asked Arjan (from NKON) if that was a typo (because his Enercig 18350 cells were also rated “14A”) and he answered that it was just the information he got. I got them in today, and without being able to test them like HKJ does (they do measure 715mAh on the Opus :+1: ), I easily got 1160 lumen out of the little Supfire with one.

I put a 3500k XHP50.2 in my Amutorch TC750 Shadow. Wasn’t real happy with the cooler tint it came with. Think it was around 5700k or so. I like the new tint but there is a lot of tint shift from the center of the hot spot to the bleed. Only noticeable up close though.

Thanks for that info djozz!
Could that be a “reasonable” high drain battery, an alternative to the AW IMR16340 15C 550mAh (Red)?
Now I am also curious because of the Enercig TN14500HP 650mAh , which might be a good alternative to the EFEST IMR 14500 Purple (despite HKJ tests show some inconsistency between the tested batteries…).

Monday, I just built a modest Sofirn C8f with XPL-Hi V3 3A. It will be a gift, with Mtn's 17mm fet+1 driver. I'm getting better at teaching people the D4 firmware.

My problem... It is a very nice light. I had to test it, of course, and now it will be hard to give away.

My other problem was getting 18awg through the holes in the shelf, and then doing the spring bypass with it... I had to strip the length of the spring plus the board width because the insulation didn't fit through the driver's positive LED-wire hole. It was designed for maybe 20 or 22 awg, but I am stubborn. So I soldered the base of the exposed lead to that hole, and the end to the spring. Should have just gotten high current springs....

hmm hi draw batteries, a JST60 plug and a 60C drain rc flight pack, hmmmm. :open_mouth:
