Lumatek Zeus 1000w Xtreme PPFD C02 LED Grow Light. 

If you’ve ever looked at a grow tent and thought, “Yes, this is nice, but I wish it could double as a small sun,” then the Lumatek Zeus 1000w Xtreme PPFD CO2 LED Grow Light has arrived to answer your slightly dangerous prayers. This isn’t just the newest flagship in Lumatek’s already blindingly good Zeus range - it’s the most powerful, most intense, and most gloriously over-engineered LED Grow Light they’ve ever unleashed on the market. Built by growers, for growers, it’s been forged in the crucible of hands-on horticulture and technical obsession. If plants could pick their own lighting, this is what they’d go for. And then they’d ask for sunglasses.

For Professional & Craft Gowers. 

Let’s start with the big numbers, because they’re not messing about. This LED Grow Light hurls out a phenomenal 2925 umol/s of PPF, with a max efficacy of 2.9 umol/J, putting it right at the top of the pile for pure output. That sort of light intensity isn’t just high - it’s interstellar. Designed for grow spaces of 1.5 x 1.5 metres with supplemental CO2, it creates a perfect storm of light and atmosphere to supercharge plant growth. And if you haven’t plumbed in a CO2 system yet, not to worry. Simply raise the fixture and you’ll still get gorgeous, even coverage across up to 1.8 x 1.8 metres - just with slightly less brute force.

Xtreme By Name. Xtreme By Performance.

The Zeus 1000w Xtreme PPFD CO2 isn’t just about light quantity, though. It’s about quality, consistency and control. Lumatek’s full spectrum output ensures your plants get the ideal wavelengths for both veg and flower stages. It’s the horticultural equivalent of a balanced diet, only instead of fibre and protein, you’re delivering blue and red photons at precisely the right ratios. The fixture uses Samsung, Osram and Lumiled diodes, powered by Lumatek’s own high-efficiency drivers, and the entire lot is coated in a clever Clear Glue protection layer that improves light transmittance to a staggering 99%, while offering corrosion resistance, diode longevity and IP65 waterproofing. You could practically hose it down. Not that we’re recommending that.

Premium Lighting from Seed to Flower.

Now, let’s talk control. Because this isn’t some clunky on-or-off contraption from the dark ages of indoor growing. The Lumatek Zeus 1000w Xtreme PPFD CO2 LED Grow Light offers full 0-10V dimming, with steps from 25% to 100%, meaning you can tailor the output for propagation, early veg or explosive flower depending on your grow stage. Want even more precision? Pair it with the Lumatek Digital Panel Plus 2.0, and suddenly you’re orchestrating sunrise and sunset simulation, temperature-based dimming, and full environmental control for up to 100 units. It’s like having your own climate chamber, minus the freezing Antarctic winds.

10 Bar Power. Cool Operation.

Of course, all that power generates heat, which would be a problem if Lumatek hadn’t built this fixture to run cooler than your nan’s conservatory in February. Thanks to the modular design of ten magnetic light bars, the passive cooling is exceptional, with even thermal distribution that prevents hot spots and boosts diode longevity. Maintenance is as simple as a wipe with a damp cloth.

Installation is equally fuss-free thanks to its magnetic snap-fit bar system, and if you want to remote-mount the driver to reduce canopy heat even further, that’s baked in too. With the driver attached, you’re looking at 3668 BTUs/h, but move it offsite and that drops to 3411 BTUs/h, giving you more control over the microclimate in your grow space. 

Massive Performance. Massive Flowers. Massive Flavours.

Finally, let’s touch on longevity and quality, because this LED Grow Light isn’t just some flashy bit of kit destined to pack up after a couple of harvests. Lumatek are UK-based, with real offices, actual phone support, and a five-year warranty that means they’ll still be around long after some of the budget brands have disappeared in a puff of warranty-voiding smoke.

The Zeus 1000w Xtreme PPFD CO2 is rated to 60,000 hours, built like a tank, and tested by people who actually grow things - not just spreadsheet warriors in marketing departments. From stealthy cupboard setups to industrial-scale operations, Lumatek has spent decades perfecting lighting solutions for every type of grower. This model is the crowning achievement of all that experience.
