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 non-pro version uses fewer diodes per bar). 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.

The light ships as a kit and requires a couple minutes of simple assembly to attach the bars to one another and connect the driver to the lamp using pre-terminated threaded connectors.
