Migro is back with not just one but two grow lights designed for medium-sized grow tents and spaces. The ARAY 4x4 and ARAY 5x5 are Migro’s latest grow lights. Designed to replace the ARAY 8 and ARAY 12, these new grow lights deviate from the design of their predecessors. If you want to switch to the ARAY 4x4 and 5x5, read further.
So what can one expect with these new grow lights from Migro?
What’s new with the Migro ARAY 4x4 and 5x5?
The overall design is the first thing you’ll notice with the Migro 4x4 and 5x5 LED grow lights. It deviates from the modular design of the ARAY 8 and ARAY 12. While no longer as compact, the Migro 4x4 and 5x5 feature a folding design that comes in handy when storing or transporting the grow light.
While the non-modular design might disappoint some, it isn’t a bad thing at all. For one, the Migro 4x4 and 5x5 have fewer moving parts, which means fewer things to worry about.
Another improvement in the design is the oversized heatsinks. While the ARAY 8 and ARAY 12 have good heat dissipation, the Migro ARAY 4x4 and 5x5 now have better heat management while remaining passive. Yes, that still means less power consumed because you don’t need any active cooling system for the Aray 4x4 and 5x5.
The older Aray 8 and 12 run on multiple drivers. The new design of the Aray 4x4 and 5x5 only needs a single driver to run the grow lights, which again equates to more efficient use of power, fewer sources of heat, and one less component that may break down.
Also worth noting are the LEDs used in the newer Migro grow lights. The Migro ARAY 8 and 12 use a mix of Samsung and Osram LEDs, while the ARAY 4x4 and 5x5 use Samsung diodes exclusively.
The newer Migro grow lights have more diodes loaded. The Migro ARAY 4x4 has 2860 diodes, while the 5x5 has 4224. Compared to the previous 1728 and 2552 diodes on the Aray 8 and ARAY 12, the higher diode count ensures uniform lighting across the canopy. When it comes to the usable PPF, the Migro 4x4 and 5x5 get a slight boost. Meanwhile, the PAR remains the same at 2.7 umol/joule.
Should You Buy the ARAY 4x4 or the ARAY 5x5?
The single-driver design is one reason to consider the ARAY 4x4 or 5x5 if you already have the ARAY 8 or 12. The newer driver is more efficient and produces less heat than running a pair together on the old ARAY grow lights.
If you’re very particular about the PPF, switching to the ARAY 4x4 and 5x5 is logical. The added diodes allow for more consistent lighting across your canopy, which equates to better quality yields.
