This bright white LED grow light is named “Mega” not for its size but for the increased production and large footprint it will supply to your canopy.

Using only 650 watts, this light is perfect for growers looking to cover larger areas using less. This unit is part of the NextLight Commercial Series. This distinction means each unit is covered by a 5 year full manufacturer’s warranty, has a 100,000 hour life rating, is UL listed and you will never have to change a bulb again.

The Mega is designed to meet the needs of commercial and home growers alike. We understand excessive power consumption, bulb replacements and heat are the biggest problems indoor growers face. The NextLight Commercial Series alleviates all of those issues. Coming in at 2.15 PPF/Watt, the Mega is the most efficient full spectrum LED, period.    

NextLight’s Full Spectrum provides the same sun-like qualities plants love without the negatives of high energy requirements and high heat.

Using NextLight’s Full Spectrum you will see faster growth, tighter internodal spacing and increased production overall.

Includes 120V and 240V High Voltage power cords.

This unit has daisy chain option: do NOT daisy chain more than 2 Mega fixtures per 15 amp 120 volt circuit and no more than 4 Mega fixtures per any 240 volt circuit.

NextLight vs. Other LEDs

What sets the NextLight Mega apart? Well, it's the light! 

The NextLight uses mid-power Samsung LM561B LEDs, not just reds and blues like other LED grow lights. It's better for your plants, and makes it easier to inspect your canopy No more looking through the purple haze. 

An Unbeatable 5 Year Warranty

There's nothing worse for your grow operation than having to stop production.

That's why NextLight provides a loaner light if you have any problems. You can keep on growing while repairs are being made. 

Tested and Proven to be Safe

Any time you mix water and high powered electronics you're creating a safety hazard.

The NextLight is one of the few grow lights with Underwriters Laboratories Inc. (UL) approval for damp and dry conditions. 

It's made here in the USA with US and imported parts.
