Low Energy Designs Ltd | SunRAY

Customers typically use the SunRAY 10 for High Bay, Low Bay , Freezer warehouses, cold stores proving to provide over 75% in actual energy savings.



SunRAYTM LED light is capable of providing between 40 – 70% cost savings, ideal for high bay lighting in warehousing, production/ manufacturing or industrial environments. An intelligent, long lasting, bright lighting system that reduces energy consumption, lowers carbon emissions and allows the customer to be in control of light intensity and associated costs. Customers have typically used the SunRAY to replace 150-400 Watt High Bay luminaires.

SunRAYTM is built in the UK and uses high flux LEDs on thermally superior, modular boards. This technology used in conjunction with our software controlled, LED temperature monitoring ensures maximum LED life. Our software uniquely allows the user to influence the maximum temperature on the LED PN junction, thus enhancing the life of the product.


Functions & Features:

-          Fully programmable:

Fully automatic light-adjusting dusk-to-dawn sensor (the light either increases or decreases brightness automatically.) A range of 32 light schedules can be programmed facilitating various power saving modes.

-          Photovoltaic (PV) sensor:

Adjusts the LED light output in response to ambient light levels and is fully programmable.

-          PIR movement sensors:

Used to trigger a single light or group of lights in a common area.

-          Automatic LED temperature control:

Light output will automatically reduce if the PN junction exceeds the programmed maximum.

-           Radio control:

Full remote control of all parameters is possible from a control PC via a radio interface. No need for cables or access equipment.

-          Additional Features:

Remote power outlet control, monitoring, LED max/min temperature setting, scheduling on/off times, fault reporting, 100% dimming from any outlet power, ramping power timer & system diagnostics.

-          Colour rendering:

Our standard package has Ra> 75.

-          Wireless Control:

Wireless control of luminaries allow for 100% customisation of lights.
