COB Efficacy

Hey Guys,

Just wondering if anyone has any information regarding the efficacy of the new gen 7 Vero 29 driven at low currents 1050ma, 700ma.

I have heard efficacy of 1.9 umol/joule but am wondering how that changes at different drive currents.

also if anyone has any information regarding the efficacy in umole/jouleof citizen clu058 1825 top bin at 1050 and at 700ma that would be great as well.

Thank!

Heres some relative charts. most chips are pretty similar at low currents. at higher currents the top gen 7 vero (68V "C") is right at the same performance as citi gen5 clu058-1825. so clu058-3618 gen 5, clu058-1825 gen6, and clu058-3618 gen6 should be a little above that line. at price/performance you'll see why im all in on the $17 luminus cxm22 below 70W

What are the axis on that graph?

X: Watts
Y PPFD/watt on-axis at 12" in free space

Are there any PPFD/efficiency calculators for the newer COBs? (vero g7, citi g6, luminus)

Building some new lights and you sold me. Just seeing what I'm going to need for what PPFD/square foot.
