NextLight Mega Pro – 640W LED Grow Light

The NextLight Mega Pro has the power and versatility for all stages and styles of indoor growing. Used primarily for high intensity flowering needs, the all new, Onboard Dimming feature allows for more control over desired light intensity. Output can be adjusted between 25%, 50%, 75% and 100%.

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. With their latest line of fixtures, NextLight continues 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.
