How many watts does a street lamp usually have?

How many watts are street lamps 150W-400W?

1, the power is based on the demand of the road. Generally, the design of less than 8 meters uses about 250W street lamps, and the design of more than 8 meters uses 400W high-pressure sodium lamps.

2. The power will depend on the grade of the road: generally, high-pressure sodium lamps of over 400W are used for the primary trunk road, and 150W are used for the auxiliary road.

3. Mercury lamp, sodium lamp, LED lamp, etc. Have special power, and the power is very different.

Extended data:

Common street lamps: low-carbon electrodeless street lamps

Widely used for road lighting in factory roads, highways at all levels, urban trunk roads and other places.

operating characteristic

1, using electrodeless lamp light source, saving about 80% electricity compared with incandescent lamps with the same brightness.

2. The service life of the light source is as long as 60,000 hours, which greatly saves the use cost and is especially suitable for road lighting which is difficult to replace.

3. By optimizing the light distribution design and selecting imported 99.99% high-purity aluminum reflector, energy saving and high efficiency are significantly improved, with high color temperature, superior color rendering, color rendering index >: 80, natural lighting, no stroboscopic and glare.

4. The surface of the transparent part is specially strengthened, with high light transmittance and good impact resistance, which ensures the long-term use of the lamp in harsh environment.

5. Installation mode: it can be used for supporting installation of φ 50 ~ 62 mm light poles. ..
