How much more mass did the amber provide?
Well some UFO knockoffs are using 590nm yellow/orange.Absolutely amazing. So the next question naturally...is are there any lights currently available that include the Amber spectrum?
I'm having trouble sleeping lately because I ordered UFO with Red 630-Blue 460-Orange 615 in 7:1:1 for flowering. Have I screwed up with those reds?
That seems like a high cost per lumen, $829 for a 7500 lumens of LED light. Not to mention 140 DC amps is nothing to sneeze at, even though it's only 3.5 volts, still it's 490 Watts.
What am I missing here? Are there better sources for cheap LEDs that are more efficient in terms of lumens per watt.
