I hooked the string straight up to a 2 amp power supply with no current regulator. I forgot to use the LM317 and resistor. Two times the current theyre rated for. Pretty sure I ruined every red. The blues are 45 lumens, and the reds are supposed to be 120. If I turn the blues all the way up those 4 outshine 6 red.

the old saying,
the candle that burns twice as bright burns half as long...

up that an order of magnitude for your diodes...

So I guess the LED show is delayed until I order all the reds again plus a few FAR reds to see about this Emerson effect. Should put the order in today and they ship pretty fast.

Peace

Good choice on the JW C99. Great smoke though only decent yielder outdoors in the sun. Not the most vigourous plants, factor that into your assessment. The AKs should show more vigour.
