The Lumatek ATS (formerly Attis) 300w Pro LED Grow Light is a powerful, full-spectrum lighting solution for your indoor grow room. Expertly designed to provide even coverage over 1m square footprints, making it an ideal 400w HID replacement. 3-year warranty for full peace of mind. This newer 'Pro' version offers significant efficiency improvements over the Lumatek ATS 300w, providing more photons per watt of electricity consumed.

With the advances in technology and fixture performance, high-quality LED horticultural lighting is now a credible option offering a significant return on investment to cultivators. Lumatek ATS Pro full spectrum horticultural LED solutions balance light quality (spectra) with light quantity (intensity and duration) sufficient to provide sole-source or supplemental grow lighting for propagation, vegetative and flowering growth periods of indoor-grown crops.

The array of the new ATS Pro range create a uniform spread of light at short distance from the crop enabling good penetration of canopy without hotspots and excessive heat. The innovative heat sink and use of passive natural convection has eliminated the need for a fan, reducing noise output and significantly increasing the life span of the fixture as it has no moving parts.

For different cultivars, propagation and vegetative growth periods this agile fixture may be dimmed without losing efficiency. The high efficiency and low powered LED configuration reduces the temperature of the LEDs increasing the output and improving light maintenance.

ATS300W Pro Range

The new Pro line of ATS is built using high-quality Lumatek controllable drivers and latest generation higher efficiency top bin White, Red & Far Red Diodes.

The upgraded diodes are now more evenly distributed across the whole length of the light bars resulting in a larger and more even light spread and footprint.

Other new features of this line include: New IP65 rating; Clear Glue protection cover technology on the LED bars, resulting in higher light transmittance of 99% without light loss, extended lifetime of diodes and extra corrosion resistance; And new Control capability with the Lumatek Control Panel Plus 2.0.

Full Spectrum

Lumatek LED grow light solutions use a blend of white, deep red & far red LEDs to produce a highly efficient light source calibrated to provide high intensity, stable and uniform output for optimal light absorption.

Previous generations of LED grow lights used a mixture of royal blue and deep red LEDs to target chlorophyll absorption peaks. Whilst these solutions worked adequately they missed out important spectra for 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 advancement in LED technology has produced a high powered LED grow light with passive convection cooling. This fanless design means no moving parts so Lumatek LED fixtures are extremely robust with a long life span and operate silently.
