GS Sunray is a series of versatile grow LED lamps designed for assimilation lighting and cultivation. The main goal of the series is to provide a type of light needed by the plants throughout their whole life cycle. GS Sunray lamps fully meet the physiological needs of plants which are grown without access to the natural sunlight.
Application of the full color spectrum allows to accelerate the photosynthesis process, what makes the plant grow faster, stronger and healthier. In the right hands our lamps, combined with the knowledge and appropriate way of cultivation, are a guarantee of numerous, high quality crops.

All of the GS Sunray LED lamps are equipped with a control panel on a long cable, what gives you the control of all four light channels individually. An experienced grower can freely adjust the spectrum and light intensity adequate to needs of the cultivated plants. If the control panel gets disconnected, the LED lamp remains active giving the full color spectrum on all channels.

GS Sunray series has an unique passive cooling system of a great efficiency. This allowed us to eliminate the common problem of a high temperature management inside the growing room. Furthermore the low temperature has a positive effect on lifetime of the lamps, which will operate failure-free for over 10 years. It’s also noteworthy that our lamps are more compact than other products of this type, because the power supply is located on a long cable.

Energy efficiency, durability, high quality – these words describe our lamps perfectly. GS Sunray lamps were created for both amateurs and professionals.
