Introducing the brand new Sun System RS 1850 LED. The leading American grow lights brand Sun System is now available in the UK through us.

This unit hinges at the centre bar allowing for maximum versatility. One of the most versatile we’ve seen in terms of manoeuvrability. If you like the idea of being able to easily transport and pack your LED unit away, then this will satisfy that need. It also comes with two sturdy hangers too! (As illustrated in product imagery).

However, it is by no means a one trick pony…

The Sun System Rail System (RS) 1850 LED is a 6 rail, foldable LED producing 1850 μmol/s with an efficiency of 2.5 μmol/j. This fixture is DLC listed, IP65 wet-rated and comes complete with a manual digital dimming button and an internal embedded smart controller that is compatible with the Gavita e-Series Controller. Together, these features give you the ability to control up to 500 fixtures (e-Series Controller required, sold separately). The Sun System RS 1850 utilizes top-bin Sun System-brand diodes to produce a full-spectrum light source. The RS 1850 operates at 120-277 volt.
