NextLight Mega w/ Com Port 650W LED Grow Light

Replaces your Traditional 1000W HPS DE 1:1

DIMMER NOT INCLUDED! NextLight Com Port is compatible with most 0-10V dimmers. NextLight Mega w/ Com Port does not dim to off. These fixtures will dim no lower than 10%. A timer/contact relay is needed to achieve full shut off. Contact NextLight for additional dimming questions. 10' CAT6 cable included.

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.

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.

NextLight Full Spectrum LED

NextLight fixtures emit a full spectrum, bright white light which is more sun-like than even your traditional HPS. Using this spectrum you can expect tighter internodal spacing and better overall quality.

Contrary to popular beliefs of the past, NextLight continued to pioneer the use of bright white, full spectrum LED, which has now become the gold standard of grow lighting.

NextLight's Full Spectrum is easy to work under and provides the same sun-like qualities plants love without the negatives of high energy requirements and high heat.
