Solar Street Light Comparison

DX3 Solar Solar Lighting vs. Traditional Lighting Solution

Traditional street lighting requires significant infrastructure, engineering, and costly installation including trenching of cabling. Power from the grid is required to utilize the lights, causing a long-term ongoing cost.

DX3 Solar Powered Street Lights eliminate grid power consumption. They are self-sustainable, solar powered, LED lighting systems which intelligently provide light at night without the need for external management or control.

Traditional lighting solution (High/Low Pressure Sodium Light)

Typical high or low pressure sodium lights have very low efficiency. They output light in a very broad spectrum including a significant portion outside of the human eye visible spectrum. They also have high light pollution by flooding light sideways into the atmosphere.

Traditional lighting requires power from the grid. The actual power consumption of typical “200 Watt” high pressure sodium lights will be 230 Watts including other reactor/ballast losses. Consumption is even higher when you consider the losses within the cabling. The technicians providing installation and maintenance are exposed to an electrically hazardous work environment because of the grid connection.

Traditional lighting has a complicated installation process with a number of professionals involved. Engineering needs to develop detailed designs to bring the power to each light pole. Crews need to dig trenches, lay armored cable, and connect them to the grid. They also need to connect and test the power in each pole to each light head.

Typical high pressure sodium lights run very hot (losses), which can easily exceed 300°C. This will result in lens discoloration and case damage. In addition, they produce infrared light which attracts insects.

DX3 Solar Powered Street Light

DX3 Solar Powered Street Lights use an extremely efficient LED which only needs less than 60 Watts to achieve the same lighting output effect as 200 W high pressure sodium system. It also has a narrower light output spectrum (primarily in the human eye visible region) and it focuses the light toward the ground, not out into the air. All DX3 solar lights are DarkSky Compliant.

Power is supplied by the DX3 Solar charging system which is completely self-sustaining. Installation is simplified because it does not require a grid connection. Each DX3 Solar Powered Street Light is a simple, stand-alone design. There is no trenching, pulling and live grid-connected testing. DX3 Solar output settings are adjusted according to the client requirements. Installation only involves installing the lighting system on the pole. This can even be done before the pole is erected into place.
