Facts Not Feelings

Somewhere along the way choosing a grow light got complicated... MIGRO spent the last 2 years listening to their fans (and critics) to understand their concerns and needs – simultaneously they’ve tested over 150 LED Grow lights on the market today.

Better Lighting Performance

The MIGRO ARAY 4 is designed to take the guess work out of picking the right grow light for you – better lighting performance with future proof extendability from the team here at MIGRO that you can trust.


Ultra Efficient

The MIGRO ARAY 4 is an ultra-efficient LED grow light with a high efficacy of 2.7 µmols/joule, meaning it emits more light per watt consumed, resulting in increased yields while minimising electricity usage. With an average daily electricity cost of £0.76, it provides an attractive option for growers looking to reduce operating costs.

Inspired By Nature

The light is equipped with premium Samsung LM281B white LEDs and Osram 660nm Reds, carefully tuned to generate dense growth during the vegetative stage and promote vigorous growth with a high concentration of flavonoids and aroma during flowering.


Modular - Grows With You

Like other lights in the MIGRO ARAY series, the ARAY 4 features a modular design, allowing growers to join multiple light modules end to end or hang them side by side to cover any size of the grow space. This means that the MIGRO ARAY Series grows with you and when its time to upgrade... no worries. Just buy another ARAY and clip it on. It's as simple as that. Genius! 

Dimmable Remote Driver

The MIGRO ARAY 4 LED Grow Light comes with a remote mountable LED driver with dimmer control, providing growers with the flexibility to adjust light intensity as per the plants' needs. With its super long cable, the LED Driver can be stored outside of the grow tent giving full control to the grower without the needless opening and closing of tent zips. Not only does this prolong the life of your tent, but it massively reduces temperatures inside the grow area too. 


Samsung and Osram Diodes

The MIGRO ARAY 4 is equipped with premium Samsung LM281B white LEDs and Osram 660nm Reds, providing a balanced full spectrum output for all stages of plant growth. As you'd expect from Shane, only the very best will do. 


Massive Output. Tiny Running Costs

One of our favourite features of the MIGRO ARAY 4 is its remarkable energy efficiency. Under our tests, we successfully flowered plants with the MIGRO ARAY using no more than 70% of its potential power. That means that even with todays crazy electricity prices, the MIGRO ARAY 4 costs around £0.76 per 12 hour day to run. 

The Growers Grow Light

This is a very intelligently built light. The attention to detail in its build and functionality is more than palpable. The self cooling bar style construction of the MIGRO ARAY 4 means that it disperses heat really well and it has an astonishingly even output over a surprisingly large footprint. You really can tell that this light encompasses so much experience and expertise from the guys at MIGRO. Every little detail seems to have been painstakingly worked over.  

Premium Build. Premium Performance

The MIGRO ARAY series is taking the grow world by storm and it's no wonder to see why. The MIGRO ARAY 4 cool running and packed full of only the finest parts & components and its modular, build as you go, plug and play functionality makes it stand a generation ahead of other LED Grow Light manufacturers. The MIGRO ARAY 4 is incredibly well priced and will no doubt leave other LED grow Light manufacturers scratching their heads. 

The MIGRO ARAY 4 is strong, robust and seemingly future proof with its modular construction. This thing looks like it will last for years and with the impressive warranty with MIGRO, you can be sure that it will. We love this light.

The MIGRO ARAY 4 is a superb lighting solution for grow tents of all sizes making it an awesome choice for beginner or connoisseur cultivators alike.
