Which is brighter, tunnel street lamp LED 80W or sodium lamp 150W?

The purpose of tunnel street lamps is to provide enough illumination brightness to ensure that drivers can clearly see the road and surrounding environment in the tunnel, thus improving driving safety. When selecting tunnel street lamps, factors such as brightness, energy efficiency, service life and maintenance cost need to be considered.

LED (Light Emitting Diode) is a kind of semiconductor light source, which has the advantages of high efficiency, long life and low energy consumption. The brightness of LED street lamps mainly depends on their power. Generally speaking, 80W LED street lamps are brighter than 150W sodium lamps. This is because LED street lamps adopt advanced optical design and efficient luminescent materials, which can convert more electric energy into light energy and provide higher brightness.

Sodium lamp is a kind of high-pressure sodium vapor lamp, and its brightness mainly depends on its power and bulb design. 150W sodium lamp has higher power than 80W LED street lamp, but its brightness is relatively low due to the light-emitting principle and material limitation.

Besides brightness, LED street lamps have other advantages. First of all, the life of LED street lamps is usually longer than that of sodium lamps, which can reach more than 50,000 hours, while the life of sodium lamps is generally around 10000 hours. Secondly, LED street lamps are more energy-saving, which can convert more electric energy into light energy and reduce energy waste. In addition, LED street lamps also have the characteristics of quick start, dimming and earthquake resistance, which can better meet the lighting needs of tunnels.

To sum up, 80W LED street lamp is brighter than 150W sodium lamp. When choosing tunnel street lamps, besides brightness, we need to consider factors such as energy efficiency, service life and maintenance cost, and choose the most suitable lighting scheme.
