Rutronik is expanding its portfolio of LEDs with the new OSLON® Square Horti White LED GW CSSRM4.HW from ams OSRAM. The new generation scores with a higher photon flux and industry-leading brightness. It is the first component from ams OSRAM to be classified according to photon flux density at 85 °C. This ensures a better match with typical operating temperatures, making it easier for system designers to perform complex calculations. In contrast to conventional white LEDs, the use of an individual phosphor solution ensures improved effectiveness. Like its predecessor, this generation of Horti White LEDs also comes in a robust and compact design and impresses with its proven reliability as well as long service life. It is ideally suited for outdoor use, e. g. in agriculture or horticulture, entertainment technology, and industrial lighting. The LEDs from ams OSRAM are now available at

The customized phosphor solution used in the GW CSSRM4.HW enables an increase in unconverted red photons, resulting in a unique efficiency. The brightness of the LEDs is 2 % higher than that of the predecessor model GW CSSRM3.HW, reaching a previously unattained level. The high-performance LEDs are installed in robust SMD ceramic housings with silicone lenses and have a low thermal resistance. They deliver reliable light at operating temperatures between -40 °C and + 125 °C.
