What did you mod today?

It looks fantastic! 2.2 amps keeps it somewhat tame with the heat. What material is that? Looks to be an SS bezel, but the rest I'm not sure of. Probably laum or titanium because of the light weight?

Hi Tom , it’s all aluminium, 2024 in classification on Europe and USA. Just it is polished … 22 Watts is turbo mode and it’s not long, because PI regulator control the overheat, it just about 30 sec , then power is slowly down and stabilizated on the thermal balanse.
P.s. sorry for my bad English :wink:

Cool :+1:

Thanks :slight_smile:

Wow. That is some great work. Good Job Tamagotchi and K_4

Agreed. Awesome job!!!

Where do I place my order for the group-buy? :stuck_out_tongue:

That is one sharp looking light :money_mouth_face:

:heart_eyes:

Trying to make a lighted switch for my D4.

I bought a ton of tiny colored 0603 LEDs from Amazon ($14 for 360 in various colors).

… but now I need resistors for them. :innocent:

QUESTION: What resistors should I buy? … preferably a link to suitable resistors from Amazon.

Thanks!

I need to know more of this :smiley:

Today I dedomed an XHP70.2 again that will fit in a resistor modded Thorfire S70S with an L6 SMO reflector.

So when are you selling these LEDs?

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!
