Sky Lumen Nguyen Flashlight

Hello All,

I am not sure if this is the right place to share my Sky Lumen Nguyen Flashlight Project. If its not let me know and I will move it. My team and I have been working on this project for about 1 year now. There were delays here and there but I think we are finally almost there and I am very excited to share it with all. I am not trying to sell anything in this thread. However if you are interested in the project you may email me at SkyLumen54@gmail.com for more info. I also understand there are tension between CPF and BLF but I do hope that reside elsewhere but not between flashlights enthusiasts worldwide. I am just here to share a common passion with all. Cheers!

Optional suspension flat oring behind glass installed
Standard matte Ti pocket clip. Screws and clip glued in place.
HA III finished. Production body parts will be sandblasted before HA III over for uniform look & gold alodyned over threads to prevent corrosion.

Any way you can just share the info about the light here?

I would like to know more about the emitter options. Saw at CPF that there will be a 14 emitter option. Is that going to be E21A or 3535 emitters? Also please keep an eye out for BlueSword’s dream bin LH351D emitter. I would like those very special emitters to make this light even more special.

Linear CC, PWM’ed FET or other type of driver?

Emitter options?

Driver LVP and reverse polarity protection? Protected cell seems an odd choice for a quad hotrod (at least I assume its a bit of a hotrod since you made it Big Smile )

Can we start with the copper version right off the bat? Fine, I’ll take two. The clip actually is such a nice minimalist design, gives it a post-modern look. Designer is an artist

never fear shadows…it means a light shines nearby

It will be a while until I can do runs with exotic metals as collectible but it would be cool to make a few.

What made you decide to go with tube walls over half a centimeter thick?

This light engine is in design phase. Was going to do 16. But actually might reduce to 12 to improve trace width.

No. I mean 14 (or 12) installed in the light. Light engine option wise there can be like +50

I got this budget Infared Thermometer on Amazon for number 5 heat test. Seems off. For example my wall seem colder than 72F and, my skin less warm than 88F, a metal surface I heated up that is burning to the hand was only 200F, icecream in the freezer at a low 17F. I guess worst case we will just use it as a guidance on temp changes rather than accuracy. I am sure someone here got one right? Are these numbers way off?

the wall could be right. you can try your temple or the inside of your mouth, should be >90

problem is two things though, these are terrible with taking temps on reflective metals and second where that laser pointer is and where it’s actually measuring can be pretty far off on something as small as a flashlight

By the way its crazy how much adrenaline I went through. Doesn’t seem much on video but I was crazy nervous and excited. Off camera we did a test run over a “normal” light and yeah it was crushed. That made me soooo worried!

I was thinking if the head got crush then I will be VERY screwed! I wouldn’t know what to do. Literal devastation. I am so happy we made it this far. In fact I couldn’t sleep more than 4 hours last night thinking about everything and what’s next. Whooo Smile

That thick wall of 7075 aluminum might as well be a solid chunk of steel!

I hope you can keep it 7075 for future runs as well.

And yeah your voice cracked quite a bit during the videos you definitely were full of nervous excitement.

Tested Proto V3 is 2011 which is softer than the First 30 Production 7075.

I am guessing the 7075 will handle the physical abuse a little better. But also hoping the 2011 will handle the next heat test better.

Silly question, are these taking modular drop-ins?

What is the advantage of that many emitters in a host this small?

Also a good final test would be a drop/throw test I think, impact resistance would go a long way to showing durability too!

The more LEDs you have the better the efficiency at lower levels.
Take the X80GT for example with its 18 XHP50.2. This light can run 4000L level SUPER LONG heat wise vs a light of similar mass running a single XHP50.2 pushed to 4000L.
More LEDS = Greater turbo lumen. Always exciting to push boundaries.
More LEDS = more enjoyment while the LED is ON or OFF Wink
This specific light engine will also be especially useful for photography, videography, diving, diffuse lantern, ceiling bounce, woods navigation, attics, real estate illumination…

Yes impact tests is very important and it’s test number 7. Still have 5 and 6 to do today though. Smile

I totally missed “impact test” in the list Facepalm

I’m sure it will pass these next tests with flying colors, hopefully you can get some sleep soon then haha!

Actually running a 5100mAh 21700 cell with a quad white2 is no joke. The light will get WAY TOO hot to hold at some point and I am really not sure if the all the internals can hold up to the heat. 18650 volatge sag faster so the max heat period isn’t likely too long but 21700 should last a bit longer. Gotta set this up outdoor to be safe. Video will be boring to watch but the test is crucial to see how the electronics hold up.

Anyone want to guess how long it takes for the light to get to Too Hot To Hold?

With quad Osram CSLPM1.TGs I’m guessing 3 minutes or so considering the amount of aluminum. Of course too hot to hold is subjective, so I can see it being extended out to 4 minutes.
