What did you mod today?

Today I finally wrapped up a mod that I’m quite proud of. Focused the optics and repolished the bezel. It’s all ready for sale now. :slight_smile:

A quad S41s with two xpg3 5500k high cri and two nichia 219c 4500k high cri.
Highly polished.
One of a kind H17Fplus high current version driver.
23 Amps from a single 18650! Around 4000 lumens if high cri!
I need to test it with an 18350 yet. I was a bit timid before but now we have a nice 18350 from Aspire.

If anyone is interested, please send me a PM. Let’s try to make a deal. :slight_smile:

_Edit: A_long the way I have bragged about the power of this light, considering it the highest of it’s class at 23amp draw from one cell. So, I am quite embarrassed to reveal my latest findings.
When I first took measurements, I did not have the battery tube in the circuit. Turns out, this stainless steel tube has quite a bit off resistance. From the best that I can measure, I am getting more than a .2volt drop across the battery tube. Measuring the circuit with the light assembled gives an amp draw of “just” 18amps. This is still right up there with the best, but I believe some of the D2 builds have surpassed this number. It also draws over 11amps from an Aspire 18350. _

The leds are also 5700k and 4000k and not as I had listed here. Sorry friends!_

What did you do to the driver?

The driver was a gift from dr jones. It is the successor of H17F called the H17F+ built specifically for high power flashlights like triples and quads. I believe It’s the only one he released. It has a very low resistance fet(maybe the best we’ve seen?). I think this is what you were asking? Else, in this light I fully potted the driver with a home brew potting material.

I just find Lexel’s Skilhunt H03 shorty mod 2 hours ago in a headlamp topic. And I really liked the idea and I have an Astrolux S41 what I use with the long tube so I got a spare short.
I made this complete cuteness of the H03 and the S41 short tube. It is 65,05mm short and 65g with Aspire 18350 battery. Searched for it and found that I need to move the O-rings toward threads on the short tube and need to make the diameter at the O-ring grooves smaller to fit.


From left to right: Manker U11, Astrolux S41 18650, Flat top unprotected 18650 battery, Skilhunt H03 Shorty, Skilhunt DS10 16340, Convoy S2, Skilhunt H03 original 18650 tube

Did a similar mod to the H03 using an S42 short tube, but i need to do something about the exposed orings.

I used Lexel’s solution for this and it works nice. I gone down to 20,05mm at the grooves next to the threads and that is enough to fit the O-rings.

I also tested o-rings from Convoy UV lights that fit perfectly without reducing the diameter

Yes thanks, i will do this eventually.

Thank you also to Lexel for a great mod. :wink:

Steel that looks fantastic! You need to tell something about those mcpcb’s and driver and tailcap lighting. What they can do? Where can I buy them? How much they cost? I’m really curious.

looks like led4power material, very nice!

Here

Thanks!

Very nice work and pictures steel_1024.

The tint on that Emisar D1 looks very green is it the 3A tint ?

Green body, green light!HaHa

Yes, XPL Hi V2 3A

1C3, that’s one of my favorite lights right there! :smiley: (EagleEye X6 triple mod)

How do you like it’s performance?

… no comment.

Edit: The ferocious Emusarus Rex stops to take a smoke break.

Hahahahahahahha awesome pic TK :slight_smile:

I can easily see why, the cute-3 produces a really useful beam, the host is really well built, has a nice size and it has the best thermal path of any host of this size I’ve had my hands on so far, with those deep fins centered right on the led shelf, though driving it at ~3A doesn’t really push it. But since I’ve had to buy two hosts, I’ll make sure to build something more hardcore in the other one :smiley: .

This is my take on a lantern attachment for he Q8. My girlfriend thinks it is ugly but I think it looks ok.

It is a 95-or-so% downlight which has advantages and disadvantages. When carrying it, very little light gets in your eyes directly from the lantern which aids looking around. When placed on a table it is a pleasant reading light for the same reason. But if you want to illuminate an area, it has to be hung up at some height because having it sitting on the ground it will just illuminate your feet. The light is way too cool for a camping light, but I plan to put 2700K 219C's in one of my Q8's anyway, so that will be my lantern Q8. I know that a camping lantern is aimed at low illumination and long runtime, but I do not mind to have the huge output of the Q8 at hand for illuminating an area if needed.

These are the parts:

I sawed a replacement lens out of 3mm clear polycarbonate sheet, the exact same diameter of the stock lens. Polycarbonate is tough and will not crack, and it is fairly heat-resistant. I drilled two 5mm holes in it, 17mm apart. The M5 screw heads will nicely clear the reflector then. Under the head of the screws a stiff rubber o-ring was put to waterproof the lens. The 95mm diameter hood is made of 3mm aluminium sheet that I hammered into shape over a 65mm diameter iron disc that I had around (from a speaker magnet I believe it came). The outside is painted with flat black heater paint, the inside I painted with latex wall paint. I'm planning on a nicer looking and more durable flat white metal paint, but the latex paint is what I had around and works well for thetime being.

Some more pics:

The latex paint does not look great but does the job:

The beam is fully captured by the hood, the leds themselves can not be seen from any angle, just some indirect stray light from the reflector can be seen:

The screw heads clear the reflector, they are positioned right in between the reflector cups:

The lantern gives an even and fairly diffuse illumination from the hood downwards, plus little light upwards which is stray light coming from the reflector and bezel:

Standing on the table, the hood is high up enough to produce a useful light cone for reading:
