VIVOSUN VS1000: What to Know
Per VIVOSUN's own product description, the VS1000 uses Samsung LM301 diodes with a stated energy efficiency of 2.75 umol/J while consuming only 100W. It lists full-spectrum coverage spanning white, warm-white, red and far-red light for different growth stages: cool white (5000K) for germination, warm white (3000K) to speed up blooming, and red (660nm) to improve plant production. Those are manufacturer-published figures.
The description also states five levels of adjustable light intensity, a daisy chain (EXT) function to connect multiple lights to one outlet, and a 2x2 ft coverage area. Notably, it says there is no grow light fan thanks to a ventilation-hole design, which VIVOSUN frames as resulting in lower noise - a real differentiator if the light is going in a living space rather than a garage.
Included accessories per the same page: grow light glasses and a US-patented rope hanger, plus a 5-year warranty. Important disclosure: no Amazon ASIN or listing was reachable via the Wayback Machine during this research, and multiple VIVOSUN ASIN variants returned no snapshot. Title, image and feature description come from VIVOSUN's own product page. There is no Amazon star rating or review count for this entry, and we have not invented one.
