LED-based device

A light generating device comprising (i) a first series of at least two first LEDs, which are electrically conductively coupled, and (ii) a first support configured to support the at least two first LEDs, wherein:

• the at least two first LEDs comprise solid-state LEDs configured to generate red LED light;
• and
• the at least two first LEDs comprise a p-side up LED and an n-side up LED, and wherein the at least two first LEDs are configured to generate first LED light having dominant wavelengths within 50 nm of each other;
• the light generating device further comprising (i) a second series of one or more second LEDs, and (ii) a second support configured to support the one or more second LEDs;
• and
• the light generating device further comprising (i) a third series of one or more third LEDs, and (ii) a third support configured to support the one or more third LEDs, wherein:
• the at least two first LEDs, the one or more second LEDs, and the one or more third LEDs are configured to generate first LED light, second LED light, and third LED light, respectively, having different colors;
• and
• wherein the one or more second LEDs comprising a p-electrode and a n-electrode on a same side, and wherein the one or more third LEDs comprising a p-electrode and a n-electrode on the same side.
