SANLIGHT SW4

SANlight LED grow lights are extremely popular in Germany and Austria for their power and high level of quality. SANlight SW4 grow lights use only 140 watts of electricity, but have an output comparable to a 210 watts HPS. The SW4 contains four LED modules, each of which are equipped with 20 powerful Osram diodes, divided into different colours that combine to offer the complete SANlight colour spectrum. Because not only the photosynthesis is important for the development of a plant, but also a good hormonal balance, SANlight has chosen to replicate the natural spectrum of the sun as much as possible. Where other LED brands choose mainly to focus on blue (growth) and red (bloom), SANlight choses to offer the full spectrum with each colour represented evenly and where all colours are represented. The result is a powerful LED grow light that radiates a warm white light to the eye, and that is suitable for both growth as bloom.

Just like all their other products, SANlight has tried to obtain maximum light output using minimal electricity. By using the highest quality Osram diodes and electronics that have been specially tuned to these diodes, the SW4 grow lights have an efficiency level that runs up to 2.3 µmol/J (!). In achieving this, SANlight have developed a secondary lens that causes the light to be amplified so that it can penetrate even deeper into the foliage. This will allow the lower placed leaves and fruits to develop better.


 

SANlight indicates that perfect light cover is achieved when three SW4 units are used for a growth surface of 120x120 cm, if hung at approximately 15-20 centimetres above. By using multiple LED-bars next to each other, instead of, for example, one very powerful LED grow light of a different brand, the light is divided more evenly over the growth surface. An issue often found with many types of grow lights is that the light is concentrated directly under the lamps, but much weaker, and quickly declining, to the sides. Using multiple LED-bars next to each other can prevent these so-called hotspots. This allows you to hang the SW4 LED-bars lower over your plants, giving them more powerful light. On the image above this principle is pictured clearly. An additional advantage in using multiple light spots is that it virtually eliminates shadow spots, providing optimal lighting to the growing surface.
