Yesterday I built a triple in a x6 host using one of kiriba’s copper spacers, clemence’s sw40 9080 219bs and a convoy biscotti driver.
Compared to most stuff I’ve worked on lately, this one was meant to be less of a hot rod and more of a practical light for hiking/trail running use, I’m glad to say it seems to be an almost perfect fit for the role.
I used it for some trail running in the dark tonight and it worked very well, imho the cute-3 has the most useful beam profile for this application, providing a beam that lights up the trail smoothly while not wasting too much light outside of it and mantaining a good bit of reach. Once the eyes adapt to the warmth, these nichias produce the most beatiful, natural looking light I’ve seen so far and with 3 of them the efficiency is quite reasonable.
The host feels good in the hand and thanks to the abundant knurling gives good grip. It also dissipates heat well and didn’t overheat running at 2.8A continuosly. The only downside I’ve found so far is that the light is a bit on the heavy side, perhaps because of the weight of the copper spacer, an aluminium one would be a better fit for the role.
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.
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.
_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!_
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.

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.
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 .
