Nichia NV4WB35AM

Nichia website shows a new quad die LED with CSP-like size.

  • 3.65×3.65 package, custom soldering footprint
  • 9.73 mm² die
  • Cold start gives 2000 lm at max allowed current. Then you can start overdriving. Evil
  • at the rated current (1.4A) output matches XHP50.2
  • 6V only
  • 3000-5000K
  • CRI70-80
  • flat Thumbs Up
  • no DTP thermal pad
  • thermal resistance beats any 3535 LED but is slightly worse than XHP50.2
  • max continuous power is quite low, lower than XHP35

Probably low overdriving capability means it’s not a thrower LED. But great efficiency, probably little angular tint shift, probably good tint…that would make it a great choice for many lights that are between throwers and flooders. And for flooders as well.
Though 6V causes troubles. And many flooder lovers would prefer CRI90+…

Myself I’d love to have a zoomie with it.

Has anybody had a chance to try out this LED?

Only place I can find them for sale is LedRise
https://www.ledrise.eu/leduri-individuale/nichia-leds/nichia-x19-series-high-power-leds.html?led_size=3—65×3—65—mm

Seem to have a good selection of CCT’s as well.

Thanks for the heads up. The footprint is the same as 119 series.
Virence had top notch MCPCBs for it but they seem no longer available. I see ledrise has some other 119 LEDs on alu PCBs so this is a possible though inferior source.

The price is a bit of “ouch”…

Not sure why the original link didn’t work. Should be fixed now.

Yep, works.

They’re not really good at putting the correct images with their products…
But they can be seen among their LEDs on MCPCB collection.

There’s also this option, if you want a more normal star shaped MCPCB.

Shipping to Canada starts at 19 Euros for 1 LED! Ridiculous…

I just rediscovered this emitter looking at Nichia’s site, and it seems like a very obvious XHP35 replacement. Has anybody managed to obtain one yet?
