This light offers fantastic coverage in a 2’x4′ and puts up strong numbers from 6″ and up. View detailed charts at https://ppfdcharts.com/ppfd-data/migro-aray-4-pro

The Migro Aray 4 Pro is a 4-bar 265W watt dimmable light built to flower a 2’x4’ grow space. Each bar consists of 168 white Seoul Semiconductor LEDs and 12 Osram 660nm reds. The driver is a Migro-branded unit that can dim from 100% down to completely off. This light is designed to be run very close to your plants – Migro recommends a hang height of just 6” above canopy (*correction: it’s actually 8″ for the PRO version and 6″ for the RED version).
