Cree XHP70 up to 4022 Lumens and XHP50 up to 2546 lumens - Multi-die leds.

Exactly. It may be somewhat less expensive to do the MOQ from SinkPAD, but still pricey for a single person doing only a few builds.

Instead, the determined individual might consider converting non-DTP copper boards to DTP. That’s nobody’s favorite activity, but it does work… Topledlight sells MK-R on copper MCPCB w/ MOQ=5, so $20/set of 5.

I hate Cutter for being unreachable for a plain close to broke flashaholic , while always having the right stuff ;-)

I have just received This but i don’t know if this MCPCB is DTP or not

I have some of the Cutter copper stars on the way along with a Fraen reflector for the XHP70.

Last night and today I built an Eagle Eye X6 mod with Wights PZL Zener modified and the XHP70 utilizing a modified Ledil Mirella reflector. It’s pulling 5.41A and making 3043 lumens on fresh cells, cells dropping rapidly of course. The Mirella reflector, even cut down to fit in the X6, does a very nice job of smoothing the beam for a soft center hot spot.

I put the emitter on a 16mm XM-L Noctigon.

Beam Shots or none of it happened!

Interesting that with the right reflector i can make a nice spot, but 3043 lumens was lower than expected i think, is it the 1630 that is limiting? i wonder what it would do direct drive? and if there would be any gain from that.
Was this with the new FET?

Cree MK-R on a Copper Star.

Might be the best low cost bet and reflow the leds off.

I intentionally kept amperage low with Wights A17PZL driver. It’s 7135 chip based with a single chip controlling moon. Makes it much more efficient at the bottom end than throttling full power down to sub lows.

I was expecting more lumens as well, I think it’s the short fluted looking reflector. I had to cut it down pretty far to get it to fit in the bezel. So it’s substantially shorter than the stock reflector and isn’t mirror finished nor is it orange peel.

I just tweaked it to get everything mated a little better and swapped out the 20ga leads for 22ga. I also washed the Mirella after all the filing and sanding. It’s showing 3184 now with the batteries not freshly charged. Of course it’s dimming immediately, the small Efest 18350’s CAN make good current but it’s like slicing their little throats! lol They’re only 700mAh cells.

I’ll get some pics of it sitting down in the Mirella, pretty neat, definitely different. Weather is clearing up so hopefully I can get some beam shots tonight.

Makes me wonder why there isn’t an equivalent reseller like Cutter based in the US or even here is Europe. Seems LED-tech.de is one of the few I’ve come across over here and they’re not exactly on the cutting edge of new tech at the moment…gen1 XM-Ls on copper are still the cutting edge right? :stuck_out_tongue:
But surely if Australia can support a specialist electronics and lighting tech reseller like cutter then… where’s RMM when you guys need him! :wink:

Hank is unavailable for comment.

Now that you point it out, that is odd. Australia supports a lot of things one might be surprised at considering the population, but Cutter definitely sticks out when you put it like that.

Good Day LinusHofmann, and Wight,

You are missing the real reason.

All Aussie newborn are issued with a LED flashlight (we call it a torch) at birth, this is issued by the Aussie government, and it is branded with their name, DOB, & birth hospital's name.

Then every birthday these torches are updated to the latest LED technology.

And Cutter has the supply contract for the next 50 years.

Btw, this has enabled the Aussie population to greatly cut its carbon footprint, thanks to incandescent bulbs now being a banned possession...

Happy New Year!

Best Regards,

George

PS:

My torch has been updated 99 times already, & I have been informed that my 100th birthday upgrade will use 4 of Cree XHP70 LEDs.

You expect us to believe this?

They implemented that in 1992. Ask any of the Aussie’s on here.

So they issue LED flashlights to each newborn and the government sends a new flashlight with the latest LEDs every year. They thought of this long before LED flashlights became commonplace and a baby has no use for a flashlight and even anticipated new generation of light bulbs coming out back when incandescent barely changed in a century…
In addition we have a 99 year old member who keeps up with every new flashlight development and is reminded yearly of the hospital he was born in, and expects a 4 LED flashlight from a government who constantly keeps track of any time he has moved in the last century and is willing to pay increasingly expensive prices to send flashlights to all its citizens on an annual basis :smiley: :bigsmile: :stuck_out_tongue: :party:
Someone has too many lumens rattling around inside their heads

On the plus side one country has actually implemented a good idea

Keen George is Irish.

Any relation to curious george?

Right, except that these are upgrades, not replacements. That’s an important differentiation.

Thanks for the link Bort. That’s really impressive.

I read that a few months ago (i couldn’t remember what country but google knows all), its a really good idea
