Brightness was being lowered by transistor control wiring. Schematic has been updated in the instructable to correct error. Problem was transistor was wired as an emitter follower and gpio out is 3.3 volts so after base/ emitter drop of .7 volts diodes were only seeing 2.6 volts and green led’s need 3.2 Volts for full turn on. Wiring diode array to the collector and adding a base resistor to protect the transistor will correct the issue.
