The Jungle Jackson Nemesis 250W

Discover the Grow The Jungle The Jackson NEMESIS 250W LED grow light: a powerful, full-spectrum solution for both vegetative growth and flowering. With high-quality Samsung & Osram diodes (including 660 nm and 405 nm), impressive efficiency of 2.6 µmol/J and high PAR output of 559.4 µmol/s, this dimmable lamp delivers maximum yield over a coverage area of 60 x 100 cm. Thanks to its fanless design, it operates ultra-quietly and generates little heat, which reduces energy costs and promotes healthy plant stems.

The Jackson Nemesis is durable and reliable — manufactured in Spain with a lifespan of 60,000 hours and a 3-year warranty. This LED grow light is an excellent choice for hobby growers and professionals who want to invest in quality, energy savings, and improved terpene and flower formation. Choose performance and longevity with Grow The Jungle.

Optimal yield

With a high efficiency of 2.6 µmol/J and a PAR output of 559.4 µmol/s, the Jackson NEMESIS delivers intense, usable light energy that is directly converted into photosynthesis by the leaves. This results in faster vegetative growth, more compact internodes, and more vigorous flowering with higher yields per m². Thanks to the even light distribution over 60×100 cm, there are fewer shadow zones and more consistent canopy development, which improves yield and quality.

Improved quality

The full spectrum with Samsung LM282B+ PRO and Osram diodes (including 660 nm and 405 nm) offers a balanced mix of blue, red, and targeted spectral peaks that stimulate specific plant responses. 660 nm promotes flowering and flower development, while 405 nm can enhance the production of secondary metabolites and terpene synthesis. This results in fuller aromas, more intense flavors, and improved resin formation, without the high energy loss of traditional HPS lamps.

Quiet and reliable Fanless design and dimmability combine quiet operation with complete control: no noise in the grow box and stepless adjustment of light intensity for each growth phase. Passive cooling ensures stable operating temperatures without maintenance-sensitive fans, while the long service life of 60,000 hours and 3-year warranty provide financial security. Easy installation and high-quality manufacturing in Spain make the Jackson NEMESIS a reliable, low-maintenance choice for hobbyists and professional growers.
