When it comes to combining serious horticultural performance with undeniable design flair, few brands do it quite like Grow The Jungle. The Jackson NEMESIS 250W isn’t just a grow light — it’s a top-tier cultivation tool wrapped in a stunning piece of hardware that’s built to impress from seed to harvest and beyond.

Made in Europe and crafted for growers who won’t settle for less, this light delivers industry-leading spectrum quality, next-gen LED tech, and a premium user experience straight out of the box.

💡 Let’s Talk Diodes

At the heart of the Jackson NEMESIS 250W is a meticulously designed spectrum made possible by a diverse and powerful array of diodes:

728 Full Spectrum Samsung 281B+ PRO LEDs (3000K, CRI>90): High-efficiency diodes that mimic natural sunlight for all-stage growth, with superb color rendering and spectral balance.
52 Osram Duris S5 Purple LEDs: A horticulture-specific mix that includes 450nm Blue, 660nm Deep Red, and 730nm Far Red — essential for vegetative strength, photoperiod enhancement, and dense flowering.
16 Hongli 660nm Deep Red LEDs: Super-targeted to increase photosynthetic activity and boost bloom-phase productivity.
16 Hongli 405nm UV LEDs: UV diodes stimulate resin, terpene, and cannabinoid production, while also supporting stem and root development.

Altogether, this setup creates one of the most complete, evolved, and effective light spectrums on the market — tailored for superior results in both yield and quality.

⚡ What’s the Power Output?

The Jackson NEMESIS pulls 250W of true power from the wall, but don’t let the wattage fool you — this is a beast of efficiency, capable of delivering more than 2 grams per watt in the right environment. That’s elite performance in a compact and low-profile form factor.

Its high-quality dimmable driver also allows you to dial in light intensity perfectly for seedlings, veg, and flower — and yes, it’s waterproof, surge-protected, and supports Daisy Chain connectivity (for the 200W & 250W versions), making it perfect for modular setups.

📏 Let’s Talk Coverage

Thanks to its efficient footprint (30x60x10cm) and intelligent diode distribution, the Jackson NEMESIS 250W provides full and even coverage for areas up to 120 x 60 cm, with ideal intensity in 60 x 100 cm tents or grow spaces. It’s purpose-built to maximize usable canopy while taking up minimal vertical height — perfect for tents or cabinet growers where space is at a premium.

📝 Summary

Here’s why the Jackson NEMESIS 250W is one of the most exciting lights in the game:

✅ Spectral Precision: Samsung, Osram, and Hongli diodes combine for a full-spectrum profile with targeted UV and deep red enhancements.
✅ Potency & Efficiency: Over 2g/w performance, dimmable power, and intelligent heat dissipation via a 1.6mm aluminum sink.
✅ Built for Real Growers: Waterproof driver, Daisy Chain support, 1.5m cord, and a size-to-coverage ratio that hits the sweet spot for indoor setups.
✅ Made in Europe: Robust build, high-grade protection, and a 3-year warranty.

Whether you're chasing bigger yields or deeper terpene profiles, this light delivers — and then some.
