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.
