Lumatek Attis ATS 300 Watt Pro
The Lumatek ATTIS ATS 300W Pro is a high-output LED grow fixture featuring 912 Samsung LM301H diodes that deliver 870 µmol/s PPF at an industry-leading efficacy of 2.9 µmol/J. The scientifically calibrated spectrum combines 3000K, 5000K, 660nm and 730nm wavelengths to support every growth phase from seed to harvest. An 11-step dimmer provides granular intensity control, while the passive aluminium cooling system ensures completely silent operation with zero maintenance. Daisy-chain connectivity supports up to 30 synchronised units for commercial scaling. Covers 90x90 cm in bloom and up to 120x120 cm in veg. Order the Lumatek ATS 300W Pro from Plant and Flower for fast delivery across Belgium and Europe.
Lumatek ATTIS ATS 300W Pro – High-Efficiency LED Grow Light with Samsung LM301H
Achieving consistent, high-quality yields in indoor cultivation demands lighting that delivers both intensity and spectral precision. The Lumatek ATTIS ATS 300W Pro meets this standard with 912 premium Samsung diodes, a multi-wavelength spectrum engineered for maximum photosynthetic response, and an efficiency rating that minimises operating costs. Whether scaling a commercial operation or optimising a hobby grow, this fixture provides the photon output and reliability that serious growers require. Explore the complete Lumatek LED lineup for every grow room configuration.
Technical performance data
The 912 Samsung LM301H diodes at the heart of the ATS 300W Pro deliver a PPF of 870 µmol/s at 300 watts actual draw, yielding a photon efficacy of 2.9 µmol/J. The spectral composition combines 3000K warm white, 5000K cool white, 660nm deep red and 730nm far-red wavelengths. The far-red component activates the Emerson enhancement effect, boosting photosynthetic efficiency beyond what standard white-spectrum panels achieve. PPFD ranges from 343 µmol/m²/s at 90 cm to 1250 µmol/m²/s at 20 cm, providing flexibility to optimise light intensity for any growth stage. The compact 625 x 605 x 85 mm form factor and 5.8 kg weight simplify mounting, while the powder-coated aluminium housing ensures long-term durability. The Samsung LM301H diodes are rated for over 50,000 hours of operation, retaining approximately 90% of their original output after that period, which translates to more than 11 years of reliable service at 12 hours daily use.
Target applications
- Standard 90x90 cm grow tents: optimal bloom coverage for 4-6 plants with PPFD values of 800-1000 µmol/m²/s at 40-50 cm mounting height.
- Multi-fixture commercial setups: daisy-chain connectivity synchronises up to 30 units with simultaneous dimming for uniform canopy coverage across larger grow spaces.
- Noise-sensitive environments: the passive aluminium cooling system operates without fans, making it suitable for residential grow rooms where sound levels matter.
- Hydroponic systems: IP65 certification provides reliable protection against moisture and water splash in wet cultivation environments.
Optimising output and efficiency
Mount the ATS 300W Pro at 60-80 cm above the canopy during vegetative growth and lower to 40-60 cm for flowering. The 11-step dimmer enables precise intensity management: begin at 30-40% for young plants and gradually increase to 100% at maturity. The plug-and-play design requires no external drivers or complex wiring. For CO2-enriched environments, run at full intensity to maximise the photosynthetic benefits of elevated carbon levels. Periodically clean the heatsink surface with a dry cloth to maintain optimal thermal dissipation. Consider adding the Lumatek ATS 200W Pro for supplemental side lighting, or step up to the Lumatek Zeus 600W Pro 3.1 for larger professional canopies.
The Lumatek ATTIS ATS 300W Pro is available from Plant and Flower, your trusted Belgian growshop with fast shipping across Belgium and Europe. Professional growers choose Lumatek for proven performance and long-term reliability.
What grow tent size suits the Lumatek ATS 300W Pro?
The ATS 300W Pro is optimised for a 90x90 cm grow tent during bloom, delivering 800-1000 µmol/m²/s PPFD at 40-50 cm height. During veg, it effectively covers a 120x120 cm footprint at greater hanging distance. For larger canopies, deploy two units or consider the 600W model from the same series.
Can the Lumatek ATS 300W Pro replace a 400-600W HPS lamp?
The ATS 300W Pro delivers comparable or higher light output than a 400-600W HPS at 50-70% lower energy consumption. Its full spectrum outperforms the narrow orange HPS output, especially during vegetative growth. The significant reduction in heat generation also reduces cooling infrastructure requirements.
How does the 11-step dimming function work?
The built-in dimmer on the driver provides 11 discrete intensity settings from 10% to 100%. Start seedlings and clones at 20-30%, increase to 50-70% during veg, and run at full output for bloom. When multiple fixtures are daisy-chained, the dimming function synchronises automatically across all connected units.
How many fixtures can be daisy-chained together?
The ATS 300W Pro supports daisy-chaining up to 30 fixtures via the connector on the driver housing. All linked units dim synchronously, ensuring uniform light intensity across the entire grow space. The wide 100-277V AC input range ensures compatibility with virtually any electrical installation.
