Osram Osconiq S3030

Osconiq S3030 is a new mid power LED from Osram.

Being mid power means it’s not well suited for regular flashlight use. But it would be OK in a lantern.

What makes it outstanding is efficiency.
173 lm/W at 3000 K CRI90.

Some more notes from the datasheet:

  • this LED is cold binned which pumps the efficiency up. At the standard 85C it achieves about 163 lm/W. Still very good. Smile
  • 173 lm/W is at binning current. Lowering current ups the number but just slightly
  • it has a very low Vf. At the temperature of 25C that’s 2.55V at low current, about 2.98V at peak supported power. At 85C it goes down by another 0.1V. If efficiency is critital, this one needs a buck driver.
  • the datasheet lists much higher bins. If the top bin was manufactured it would deliver 240 lm/W at binning conditions. Wishful thinking.

I did some datasheet based calculations.
If you include a huge number of underdriven LEDs (the bottom of specs, 10 mA per LED, ~4.65 lm/LED) and keep them cool (easy at this current), you get about 190 lm/W with CRI90 minimum. That’s not taking into account bin lottery, I used the numbers listed as default.

But I wonder what they can do when overdriven.
At the maximum supported current of 180 mA they do 76 lm. But they are still at 150 lm/W then. They can surely do much more…

This look like competition for samsung 301b, but it look like samsung is more efficienct even at 90cri?

It indeed looks so. Quantum dots and stuff may be cool but after a closer look it doesn’t look like a top performer.
However one advantage that is has over LM301B is a standard soldering footprint. And….that’s the only major advantage that I see.
