Seoul Y50

Interesting quad die LED in 5050 format:

Highlights:

  • CRI 70-80
  • very low thermal resistance, 0.8 K/W (XHP50.2 has 1.2 K/W and XHP70.2 has 0.9 K/W)
    • but fairly small thermal pad
  • 12V only
  • on paper it’s as efficient as XHP50.2
  • there’s air gap between dies….weird
  • 3000K-5000K
