Reviews & Questions

The research and development that Lumatek have spent on this light are visible with the significant advances in technology and fixture performance, now offering high quality LED as a credible option for growers, offering significant and unrivalled return on investment. The Lumatek full spectrum horticultural LED solutions balance light quality with light quantity (intensity and duration) delivering a uniform spread of light and an even light distribution, perfect to provide single-source lighting for the entire grow cycle for your plants, from propagation, cloning, vegetative and flowering growth periods of indoor grown plants. This lighting fixture will outperform most 400w HPS lights, coupled with the drop in power consumption and very low heat output, it is easy to see why so many growers are moving to LED.

How to use the Lumatek Attis 300w LED Grow Light

The lumatek Attis series features top bin LUMLED LEDs and dimmable Lumatek drivers. The Attis 300w will adequately cover a 0.8-1m² area. For flowering and for the most abundant of yields we would recommend to go for the 0.8 m² area where possible. This makes it an ideal lighting solution for a BudBox Pro Medium Tent or the Budbox Pro Large Tent.  However, many growers choose to run two or more, side by side. In which case a larger tent will be required. Please check out our range of Grow Tents to find the perfect solution for your grow space. For a fully comprehensive kit that includes the Attis 300w alongside carefully selected equipment to get you setup, have a look at our complete kits. The 0.75m x 0.75m Complete Kit and the 1m x 1m Complete Kit both offer the Attis 300w as a lighting option.

The arrangement of LEDs creates a uniform spread of light at a short distance from your crops without excessive heat or the issue of hotspots.  The need for a fan has been eliminated thanks to the innovative heat sink and the use of passive natural convection; reducing noise output and dramatically increasing the life span of the unit as it has no moving parts.

The innovative design is extremely robust, with a long-life span and silent operation.

In the past, existing generations of LED grow lights usen a mixture of royal blue and deep red LEDs. These targeted Chlorophyll absorption peaks, however, they missed out on important spectra for optimised plant growth and lacked penetration through dense canopies, in turn, providing poor visibility for inspecting and maintaining grow rooms.

Lumatek have solved this as their light solutions use a blend of white, deep red and far-red LEDs. These LEDs produce a highly optimised, efficient light source calibrated to provide high intensity, stable and uniform output for optimal light absorption.

Why choose LED?

Lumatek LED solutions can potentially save 40% on electricity and studies indicate that LED-lit canopies can generate more yield per kWh. With studies showing growers using LED lighting may experience yield increases and changes in cannabinoid and terpene profiles, leading to more consistent medicinal product profiles from harvest to harvest.  Unlike HPS lights, there is very little degradation overtime, this means that not only will you not have to physically change bulbs, but your diodes will still be producing near on the same output, year in, year out, just like they did when new and only degrade around 1-3% per year. Lumatek LEDs are very efficient, and the less wattage equals less heat into the space, allowing for potentially lower extraction loads and operating expense. Lumatek LED drivers are intelligent and feature full circuit protection including over/under voltage, short circuit and over temperature protection. The LED drivers also feature auto-power increase/decrease to match the number of light bars connected to fixture. All Lumatek LED fixtures are CE certified LVD and EMC compliant.
