Some might argue that solar street lights aren''t as bright as traditional high-pressure sodium lamps. While this might have been true in the past, LED technology has significantly improved the light output of solar street lamps. With proper design and placement, these lamps can provide ample illumination for most applications.
CRI. CRI for LED is highly dependent on the particular light in question. That said, a very broad spectrum of CRI values is available ranging generally from 65-95. Low Pressure Sodium lamps are notorious for having the worst CRI values on the market. Typically they fall around 25 on a scale of 100 where 100 is the best possible.

In real life, high-pressure sodium lamps are still the main products of road lighting in China, but LED street lights replace traditional street lights faster and faster. Through experiments, we have designed and developed an energy-saving and environmentally friendly street lamp suitable for haze weather, and its light has high penetration in bad weather
Because of the extremely high chemical activity of the high pressure sodium arc, the arc tube is typically made of translucent aluminium oxide. This construction led General Electric to use the tradename “Lucalox” for their line of high-pressure sodium lamps. Xenon at a low pressure is used as a “starter gas” in the HPS lamp.

Photometric and electrical results obtained during this period will be presented as well as a comparison with the old lighting system that employs high-pressure sodium lamps based on
more efficient high-pressure mercury-vapor lamps, which again have almost been replaced by more efficient high-pressure sodium-vapor lamps. In the last decade, a number of street lights were replaced by efficient white-light metal-halide lamps. However, at the moment, LED street lighting is more and more penetrating the outdoor-lighting market.

High-Pressure Sodium (HPS) lights are high-intensity discharge (HID) lighting technology. They are commonly used for outdoor lighting, such as street lighting, parking lots, and security lighting. HPS lights produce light by passing an electric current through a gas mixture within a sealed glass bulb.

Adequately comparing HPS and LED street lighting installations and appropriately using the CIE mesopic theory, our research was aimed to establish the real LED potential for energy savings when illuminating streets (roads) intended for motorized or mixed traffic.
A street lighting system boosts economic growth by extending the amount of time people spend outside at night. Unfortunately, one of the major contributors to significant energy consumption is the street lighting system. The production of electrical energy produces more carbon dioxide emissions, accelerating the phenomenon of the greenhouse effect.
Street lighting is a critical component of any city's infrastructure. On the other hand, the street lighting system consumes a significant amount of electricity. As a result, many technologies and studies are being developed to reduce the energy cost of street lighting.
The existing street lighting system with HPS lamps uses a standard street lighting control unit to turn on or off the lamps. The control unit is made up of two modules: a photo switch (LDR sensor) and a 220 V, 60–100 A relay, both of which are separable, as shown in Figure 1.
Finally, sophisticated algorithms and models were employed to create regulations and plans for increasing the energy efficiency of the street lighting system [ 41, 42, 43, 44 ]. Although many ideas for reducing the energy consumption of street lighting have been proposed, there are some challenges and limitations to consider.
