5. 4000K and 5000K Color Temperatures
We offer Led Street Light color temperature options in both 4000K and 5000K. 5000K is a perfect replacement for Metal Halide. 4000K is also an option for those states requiring a slightly warmer light. Other color temperatures available upon request.
Both offer a significant improvement over high pressure sodium lights, rated at 2200K. LED street lights with a CCT of 3000K - 4000K (or a little less) are the best for street lighting in residential areas. The amount of blue light they emit is small.
6.High CRI with 70+,80+
One of the specifications you need to pay attention to is CRI (color rendering index). This is a measurement of the quality of light that the fixture is producing. It is a scale between 0 and 100. Sunlight is 100. A general rule is that you need less quantity of light if you have better quality. LED has high CRI making the quality better than most traditional light sources.
7. L70 Light Maintenance - up to 50,000 hours
Lumen maintenance relates to the lifespan of a light source. LED lights do not burn out like traditional lights. They maintain initial lumens longer. What happens is the light intensity fades gradually, but this usually takes years.
A 70% deterioration in light output is the point at which the human eye notices a decline in the intensity. But, the human eye is only affected when the light intensity of a light source reaches a level of 30%.
