Proper Use and Care

Hang fixture using supplied fixture Hooks
Hang fixture at a minimum of 12" from bottom of fixture to top of plant canopy. Less than 12" distance may burn plants.
Always allow for adequate ventilation of Fixtures to ensure your lighting system can properly cool. Failure to do so may shorten the lighting system’s lifespan.
Wipe down outside of fixture with a damp rag. Dry thoroughly with a chamois or moist cellulose sponge to prevent water spots. All cleaning should be done with the light system unplugged from its power source.
Avoid touching diodes with your hands, even if powered off.
Never clean light system with detergents or abrasives.

Spectrum

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.
