PayPal received. Thank you.

I'll try one of the Yuji LEDs to see what I think and go from there. I am still a big fan of the Nichia for brightness and longevity.

Sorry for the delay while CPF was temporarily down ...

I don't have enough extra Yuji to send you 25, unfortunately, but may be interested in one of your next batch using an XP-G2 (4000K)

There have been a couple of group buys of the Yuji here, and if you have the chance to check these out sometime, I highly recommend it. There may still be someone around who might be willing to sell you 25 for a nominal amount. The 5mm emitters hardly cost anything, but the problem has been the minimum order quantity of 1000 pieces direct from the manufacturer (plus shipping, which only adds a negligible amount per piece on such a large order)

Anyway, thanks much for continuing to create and release cool products for us here on CPF, instead of shifting over to other (massive and impersonal) platforms .... Cheers !

Do these work on 9 volt batteries?

NO!!! 1.5V operation only. They really like depleted cells that won't power cameras, Wii remotes, etc.

If you will ship internationally Sir, I'll kindly take one. Thank you!

I apologize, but I am unable to ship internationally at this time.

I have a lot of these types of devices, of various sorts, but this is the most compact and beautifully made ... thank you !

 

[greatscoot]

Mine arrived on Thursday, very nice.

I forgot to ask ... any polarity protection on these ?

Of course, with such a simple device, that would not necessarily be expected. But still would be good to know how much of a concern this might be, if fumbling around with these in the dark ... :candle:

Thank you. I have refined them a bit over the years.

No polarity protection, but when used with a 1.5V cell there isn't much worry about damaging the circuit. Do not use with anything higher than 1.5V! It is a boost circuit, and could possibly toast the LED.

Thanks for the additional info !

 

[Wildcat]

is there a sign up list for the next batch?

 

[bladesmith3]

@datiLED yes i know this is an ancient thread but... i just saw this post for the first time. i love the vamp. i was just wondering if you ever pursued this project? any chance you have one around you could part with?

 

[StagMoose]

He recently did another run.
Mentions in the thread about working on a 3v compatible one as well.

They are fantastic.
