Now Yuji can simulate the halogen spectrum by one LED

Can you believe the spectrum below is achieved by LED technology and just by one LED package instead of multi-color LEDs?

A light soece

Yujileds achieves this with one LED die and 7-phosphor which is an unprecedented complexity challenge for LED technology but we made it. We believe this would be a milestone, that LED can reproduce halogen, or CIE illuminant A in the visible lighting range spectrally.
