The Q4W of SANlight is a high quality indoor LED grow light which can be used as a top lightning in the vegetative and bloom phase. The system is designed for illumination of plants with high light demands and can be used in small and large cultivation areas.

The secondary optics (lens) have a radiation angle of 90° which distributes the light homogeneously over your cultivation area. Because of this radiation angle, the light scattering is minuscule.

The lights are daisy-chainable up to 7 lights and can be combined and used with the Q6W connected to the same power plug. When the lights are connected via the extension-cables and t-connectors they can be operated from one single power point. This light system can be used from 18 hours (VEG) to 12 (bloom) hours per day.

During VEG, less power and light output is necessary to keep your plants healthy (1x Q4W in a 60x60cm, 1-2x Q4W in a 100x100cm), during bloom higher light levels and more power is needed to give you the best quality harvest (1x Q4W in a 60x60cm and 2-3x Q4W in a 100x100cm).

LED light can be harmful for your eyes, therefore we recommend you to wear the Method Seven glasses to protect your eyes. Besides protection, the glasses filters the light to normal daylight colours which allows you to see the normal green colour of the plant. The broadband spectrum makes sure your plant gets a maximum photosynthesis rate and helps the plant regulate its hormone balance.

The LED light can be used in small and large cultivation areas. Two to three Q4W's can be used in a cultivation area of 100 x 100cm with a canopy distance between 25 to 40cm. The lights are daisy-chainable up to 7 lights and can be mixed with the Q6W.

The quality of the design and manufacturing is extremely high and is one of the most impressive aspects of Sanlight. The system delivers high light intensity (PPFD) which makes them perfect for fruit-forming plants.

The lights are build with upgrading possibilities, this means a part of the module can easily be replaced by e.g. newer LED chips, which is efficient, cost-effective and environmentally friendly.
