This 150w marvel, featuring Seoul 3535 SMD, Seoul SMD2835, and Seoul UV diodes, isn't here to play; it's here to dominate. With over two times the diodes of the competition and a UV array, it's a compact LED grow light that performs like a horticultural rockstar – all for just pennies a day.


Bigger. Better. More Diodes

In a market flooded with compact grow lights, this one stands out, and it does so by being, well, bigger. Measuring 38cm x 38cm, it's larger than others in its price range, and the increased array size ensures the diodes are spaced far enough for a cooler run. Yes, this light runs cooler than the competition – and it has a notably larger footprint. Impressive, isn't it?

High Power. Low Temperature.

Beneath the hood, or rather, under the canopy, you'll find a colossal array of 585 premium quality diodes. That's right, 585 diodes – over two times the diodes of some other popular models. Karma Horticulture cracked the code: more diodes at lower power equal high-powered performance, a cooler temperature, a larger footprint, and significantly less degradation of diodes and components. This is value at its finest – less than £150 for a grow light that's redefining the game.


Full Spectrum. Complex Flavours & Aromas

Now, about the spectrum. Ranging from 5000k, 3000k, 660nm, to UV 450nm, this LED grow light offers a unique full spectrum array with a little deep red and UV peak, enhancing flavours, botanicals, and aromas. It's like a botanical fiesta for your plants. The Stealth 1500w is the only compact LED grow light to feature UV diodes as standard, adding that extra punch to your product quality.

Ultra Efficient. Ultra Powerful

With an incredible 2.7umol/J output, the Karma Horticulture Stealth series is fully dimmable from 10% to a super bright 100%, making it perfectly suited for a full seed-to-flower grow. At 38cm x 38cm square, the Stealth 1500 is slim, well-balanced, and super stealthy – perfect for small spaces, cupboards, and grow tents up to 1.0m x 1.0m. Weighing in at less than 4 kilos, this little beauty can be hung just about anywhere with zero risk of buckling your tent.


Silent & Stealthy

This stealthy powerhouse runs absolutely silently with no moving parts and produces very little heat compared to other LED grow lights of its capability. It's passively cooled, venting all excess heat upwards and away from your grow area. Not only does this make heat management easier, but it also means savings on cooling equipment and less noise. Win. Win.

Ultra Silent. Super Stealthy 

Karma Horticulture isn't just a brand; it's a promise. Based in the UK, there's no need to worry about inflated prices or dodgy customer service. The 3-year warranty is solid, and all lights ship in stealthy packaging, with everything you need included in the box.


Grow With Flair

So, if you're tired of mediocre grow lights and want a horticultural revolution, the Karma Horticulture Stealth 1500w is your ticket. Don't just grow; grow with power, grow with control, and grow with flair.
