LED Street Light Features:

DILU Technology has recently launched a range of street lights based on high power LED (light emitting diode) technology. The range offers a selection of LED mast head lamp units designed to replace existing sodium and metal halide street lamps.
Switching to LED street lights offers up to 80% savings on power consumption and ensures a complete return on investment in less than 17 months with colossal savings over the 10 year life of the product. Resultant reductions in harmful Co2 and So2 emissions are proportional.

LED street lights have a number of useful properties, 3 of which are useful here: directionality, specific colour and efficiency. In addition to the inherent efficiency of LEDs, street light can be made very directional, casting light mostly along the roadway, with only a small amount down and none up. This will allow good illumination with the least light generation, further reducing power consumption and saving more money.

In addition, by using separate red, green and blue elements, the colour can be varied. By producing different colours at different times, colour vision can be helped while protecting night vison. At dawn/dusk, the lights product a blue/green light, complementing the red glow of the low sun, helping colour vison. At night, the LED Street lights generate pink light, protecting night vision. Red light on its own is too unnatural
