Low Energy Designs Ltd | SunFIRE™


SunFIRETM LED light is capable of providing between 50 – 70% cost savings compared with the traditional lighting solutions and is ideally suited to street, pathway and car park lighting. Customers have typically used SunFIRETM to replace 35-200 Watt HPS luminaries.

SunFIRETM 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.

Remote control provides the customer with the ability to 100% customise the light as they require, something that hasn’t and still isn’t available anywhere else in the market.


Functions & Features:

-          Photovoltaic (PV) sensor:

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

-          Automatic LED temperature control:

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

-          PIR movement sensors:

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

-          Lighting Schedules:

A range of 32 schedules can be programmed facilitating various power saving modes. These include on/off, dimming etc

-          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:

Include fault reporting, 100% dimming from any output power, ramping power timer & system diagnostics.

-          Colour rendering:

Our standard package has Ra> 75.
