Do you trust the fake Vishay MOSFET on the stock HL driver?
I have heard from drivers with its being dead after some use

The marking on my sample was fake the electrical measurements shown terrible values
compared to original Vishay SIR800 which is still worse than the Infineon

The LEDs are pulling 12amp in high and 30amp in turbo and I also have some vishay MOSFETs from mouser to replace it. For now it is Ok but eventually I will replace it with one of yours. I will contact you soon as I need some other drivers for different builds.

Orsm build grin. Did you have this out shining in the sky recently? I saw lights in the horizon here in Melbourne coming from your direction.

One more thing. We need a picture of the torch with someone holding it to give us an idea on just how big this is. Please.

Size matters hey Moose

“… SIR800 is still worse than the Infineon”

Doesn’t that depend on which Infineon? The 404 is a better performer than the 800, the best Infineon gives slightly better yields than a 404, depends on the light they’re all in just how much you can actually measure, much less see in real world use. The cells still rule the day…

Following the paper trail (specs) is always much different than actual in hand results.

Sometimes.

Thanks everyone. It is good to be a part of the comp I will post some more later.

Haha Dale I hear you and will update electronics but please dont be an enabler.

I have finally finished the light. there are some things I would do different and it needs new reflectors because the ones in it are scratched. But it works and for the time being no more changes will be made.

I will get beam shots and take measurements on the weekend

Beautiful Flashlight ” grin ” . :+1:
So much work fitting, experimenting, learning and overcoming adversity while building this enormous light. We have witnessed the birth of a unique one of a kind Flashlight. Thank You for having us along for the ride.

It matters when you are at 80% FET for example, you got also switching losses that add up to conduction losses
This is what does the fake MOSFET likely die it overheats, or at lest significantly heat up the driver

Some measurements
Weight 2.485kg
With batteries 2.89kg
136k lux @ 1m
738m beam distance

That is a flashlight. Very impressive!

Hoop · 2020-02-23T18:24:27.000Z

It turned out quite the beast. That was wild how you made the copper heatsink with plates like that, and then you sectioned it with the flats, which made it look fancy. Good work.

Brilliant, unique - the epitome of what the contest is about in my opinion. You have made a fantastic light and should be very proud of yourself.

Thanks it was something I want to build wasnt exactly what I had envisioned but I am happy with how it came out.

Heavy Metal flashlight :o
Grear work

MRsDNF · 2020-02-28T05:12:06.000Z

Watched your video and couldn’t help but do this.

This has been a fun build now I want to push the boundaries a bit more. I was playing with it at work and someone in the office thought there was welding being done without curtains. A driver and led upgrade will make me grin even more.

I have a quad with 86mm kaidomain reflectors half done. Going to use xhp35 with a taskled driver. Great white driving light housing is the base of the housing.
Then I have 4 GT reflectors and 4 SBT-90.2 which hopefully I can make it look like a GT.

Absolutely amazing work, grin! You Aussies really know how to get it done.

NeutralFan · 2020-02-29T02:04:00.000Z

Unbelievable flashlight grin! I wish I was as talented as you.
