New Nichia LED 4 Times Brighter

[Bearcat]

Yes but I better take it over to the Marketplace.

OK, precisely which location and when are going to post them?

 

[danfrum]

Yes please let us know. I'd like to buy 20.

Can anyone tell me the difference between the DS and GS LEDs? What does 20*3 mean?

Edit: I've looked at the pdf's and can't see the difference.

The NSPW500GS-K1 is the 5mm LED that people are asking about on this thread. 20*3 = 3 dies in one package (20ma x 3). These LED's are rare and only sold in Japan. Got a whole stash of em in a "W" bin in brightness and if you want I can post the picture of the anti static bag they come in These LED's are roughly 2 to 2.5 times brighter than the DS series.

Are you going to put one of those bad boys in a Fenix EO?

ARC_mania, thank you! :thumbsup

These LED's are roughly 2 to 2.5 times brighter than the DS series.

I believe you but, am still confused. If they both have a beam angle (direction charecteristic) of 15 degrees, shouldn't the GS-K1 LED (Rank V 22000-31000mcd) be producing a higher mcd value than the DS LED (Rank V 22cd-31cd)?
Am I interpreting something wrong?

OK, this ought to tickle you're fancy.

Thanks.

thanks for providing links to the spec sheets, they look like CLONES. i cant find anything in the spec sheet in the one different from the other, unless you get a different "ranking" ohhh fry my brain, i hate spec sheets.

i put both PDFs on seperate "Tabs" in a tabbed browser, and jumped between them, to find magic differences, but it just looks like the usual cut and paste data sheet, just slop the same info from the other data sheets in, and change anything that changes.
the "angle" on both of them looks very tight.

better to see what the users say, when they are driven exactally the same way, with hopefully same hours of runtime parts. If its 2X as bright as the burnt out one in thier overdriven flashlight , i'm not sure if that is different

Seems like the manufacturer has made an honest mistake regarding the specs. Using common sense here, its obvious that the three dies in the NSPW500GS-K1 LED has more surface area producing light compared to the single die in the NSPW500DS at the same drive current. I have tested the GS-K1 LED at a drive current of 13ma and it produced roughly 4 lumens of light. Sorry I don't have proof on paper as I acquired these numbers by using a light meter and comparing with a 1 x AAA flashlight which uses the old NSPW500BS series and rated at 3 lumens at a drive current of 50ma by the manufacturer. Just trying to keep things simple.

Heres the difference. NSPW500DS on the right. The flashlight on the left uses the NSPW500GS-K1 (W rank in brightness) along with a special converter that I developed. Enjoy.

So does this GS put out a lot more light than the DS driven at the same level? What is the drive level of your new converter - looks good.

This LED may be great in a tiny light like an ARC. I just recieved a Photon ReX using 4 of the DS LED's and the thing put out a huge amount of light for such a small light and only 5mm LED's. Using one of the GS LED's in a AAA light would be pretty cool.

regulater: Yes, there is more surface area producing light in the GS-K1 compared to the DS series. The output current of the converter shown in the picture can be set from 13ma to 100ma.

Here are some comparasion photos of the GS-K1 LED being driven at 13ma from a single LR44 battery. I'd say its pretty bright compared to a Sonic flashlight running 1 x AAA.

Sorry for my ignorance, but is it a white or blue LED?

 

[ARC mania]

Viren: My camera isn't one of the best and the color is off at times. The color of the beam is white but in the photo appears more blu-ish. Porbably the b2 tint has something to do with it as well.

Ah I see.... Perhaps an C0 Tint would be nice yellow

 

[regulator]

I would love one of these in a UK 2AAA light. The 2AAA side by side format is still very easy for pocket carry and has double the runtime. This format is easier to pocket carry than a single AA IMO.

Can the converter work off of 2 AAA or only 1.5 volts? The converter and LED make a very interesting combo. I really like lights that are small, offer decent lumens, AND runtime - a nice "balance" for EDC.

 

[Brlux]

Why does it look like their is an inductor mounted between the legs of the LED? Did you add that or are they shipped that way?

Edit: Is that your regulator? How the heck did you get it so small? Impressive.

 

[ARC mania]

Brlux: Yes, thats an inductor mounted on the leg of the 5mm LED. I soldered that on there. There is a driver on the otherside which can not be seen. The converter is made up of only three parts. Actually, I could have used a smaller inductor but none on hand so I had to make do with what I had. The inductor in the picture measures 3 mm in width. With a smaller inductor, you can stuff the converter into a 2mm circle while maintaining the same efficiency.

I really don't need a hundred - any one want to split a hundred with me?

Can you post a link to the sale on the CPFMP?
I`m interested in 10-20 pcs.

Same here.

 

[chimo]

I have ordered a hundred of these. When they get here, I will keep around 30 and sell the rest in lots of 10 or 20 so more people can get a chance to get some. I will post a link in this thread to a thread in the marketplace after I get them (remember that it's a busy mail season). First dibs will be given to those who have already expressed interest.
