Time to get excited!
Their prices seem be quite high. How much did you pay for them?
www.ledrise.com/leds/high-power-leds/f_1_nichia-series-219/
or from an official distributor:

IIRC it is a polarity marker, cannot remember if it is anode or cathode though...So does the little rectangle of seemingly phospor on one corner have a purpose? I haven't found anything that mentions it, and my curiosity is itching!
Ok I looked at the data sheet on Illuminationsupply for this LED. Can anyone tell me how many lumens are being put out at 1.5A?
according to the datasheet - ~340-370

Can anyone confirm these numbers? I would say that these leds can produce on a torch@1,5amp 200-250 OTF.
The Nichia NVSL219 H1 from IlluminationSupply are $5 each and this is for a premium bin you cannot get anywhere else, B10(100-110L), 92 CRI typ., Vf=L (2.7-3.1), sw45(~4500K). Basically the best of the best from the 219 H1(HCRI) series.:thumbsup:
I've seen the specs from LEDrise and they are incorrect as they include mixed info from different 219 types, and from what I've been told their H1 (HCRI) are warmer (3000K) than the XPG HCRIs.
Just as an FYI, I got some Cree XM-Ls from LedRise and they shipped from Romania. So you have a "local" LED supplier!I'm located in Romania, Europe.
