A step in evolution

The led has again evolved. Today I must share the beauty of the photonic lattice. While this part is not for the faint of heart it does look promising.

The light emitting part of the led is the same size as my ledengin 10w.

Me thinks I can get the light into the tube. I will do a comparison between the two with a few different lenses after I finish some other things.

Behold.

What colors do these come in or is it just white? You have a link for the data sheet and where to get them?

it's finally in production!

*commence chorus of angels here*

Rhyen: It was discussed here.

Info can be found here data sheet is here

Just a quick what led is it?

There is red green & blue. They have some other models but not a lot we can try to use, yet anyway.

Mine is a green. It is high current but @ 2000ma 700 lumens 3000ma, 1000 lumens 4000ma 1200 lumens well distributed. Great thermal specs too.

AVnet seems to be the only source. Look good it was hard to find.

The forward voltage is the same as a typical 3-watt LED, but the amperage requirements are off the charts. I'm guessing you would need some kind of special driver (or a series of 1000 mA Buckpucks) to ensure it's getting the amps it needs, and you'd need several high-mAh batteries to get a reasonable run time from it. Two 900 mAh 3.7V li-ions would be sucked dry in the blink of an eye, I'd think. I have a green LedEngin 10-watt, but 1) the forward voltage requirements are nuts, and 2) it gets outrageously hot. In a standard MHS set-up, the entire top end of the hilt becomes so hot that it's uncomfortable to touch. So I've never gotten beyond the Whoa-that's-bright-whoa-that's-hot testing stage. I'd love to hear a report from Sunrider on how the PhlatLight works in practice.

Sunrider the photonic lattice technology is promising and I'll look forward to hearing your results with GREAT interest, and particularly whether you find optical solutions that give acceptable results in sabers. Ineffective not-sufficiently-tightly-collimated optics for our saber purpose has often been the achilles heel with the multi-die/multi-emitter higher-output-than-conventional LEDs so if you can get those impressive on-paper lumens practically focused up the blade that will be a significant achievement. If you can find a way to do it with practical size efficient battery solutions and handleable heat management that will indeed be impressive...the very Best of Luck with your experiments.

Four AA NiMH batteries would work with these. At 3.8 volts and 2300 mAH they would last just over an hour if you use the 2000 mA set up for the LED. I wonder how bright it would be at 1000 mA and 1500 mA? It may still be bright enough just using a US 2.5 or MR/Hasbro.

This looks great! I also think that Erv' said in the CF V5 thread that he was going to try and boost the output to 2A on V5. So that should be great for this. No, you can't pull 2A+ safely from 14500 Li-Ions, but I'm pretty sure you can do with 18650's pretty easily. I think that I will buy and try some as well. Thanks a lot Sunrider, a most excellent proposition!
