LUMATEK ATS300W PRO 300W LED Grow Light. Thanks to advances in technology and fixture efficiency, high-quality LED horticultural lighting is now a reliable option offering a significant return on investment for cultivators. Lumatek full-spectrum LED horticultural solutions balance light quality (spectrum) with sufficient light quantity (intensity and duration) to provide illumination from a single source for the entire growth cycle from vegetative to flowering. The Lumatek ATS series is a range of full-spectrum LED grow lights, featuring LUMLED top-mount LEDs and Lumatek dimmable drivers. This lightweight fixture is available in 300W pro (1 m² area) and 200W pro (0.8 m² area) versions and is ideal as a single-user or supplemental grow light for propagation, vegetative, and flowering periods of indoor cultivation. The array of LEDs creates a uniform light distribution at a short distance from the crop, allowing for good canopy penetration without hotspots or excessive heat. An innovative heat sink and the use of passive natural convection eliminate the need for a fan, reducing noise levels and significantly increasing the fixture's lifespan because there are no moving parts. The ATS is a highly efficient luminaire with the 300W pro model producing 816 µmol/s PPF at 2.7 µmol/J (holder efficiency), ideal for 1m² grow spaces. Full spectrum+ Lumatek LED grow light solutions utilize a blend of white, deep red, and far-red LEDs to produce a highly efficient light source calibrated to provide high intensity, stability, and uniform output for optimal light absorption. Previous generations of LED grow lights utilized a blend of cyan and deep red LEDs to target chlorophyll absorption peaks. While these solutions performed adequately, they lacked important spectral characteristics for high-quality plant growth, lacked penetration through dense canopies, and provided poor visibility for inspecting and maintaining grow rooms. Passive Cooling: Lumatek's innovative design and advancements in LED technology have allowed high-power LEDs to grow using passive convection cooling. This fanless design means there are no moving parts, making Lumatek LED fixtures exceptionally durable, long-lasting, and silent.
