Are solar street lights Bright Enough?

Introduction

Solar street lights are becoming more popular in residential and commercial areas due to the increasing energy efficiency and eco-friendly technology demand. These provide added security by illuminating dimly lit areas after dark. Street Light Solar also offer cost savings because they reduce the need for electric light poles or cut electricity bills by using sunlight instead of grid power. Most of these solar street lights come fitted with LED lamps designed to illuminate streets and parking lots for better visibility.

In this post, we will explore the Lux standards of street lights and why they are important.

What is Lux and why is it important?

Lux is a measurement of luminous flux that falls on a surface. Lux is an SI unit of photometry, which is a way to measure the brightness of the light. Luminous flux is the amount of light given off by a source. So, Lux is a measure of the brightness of light at a given point in space. Lux is used to specify the brightness of light or illumination. It is a standard light measurement in all types of lighting, such as a home light, office light, car headlight, or street light. On the other hand, Lumen is a unit of measure for light output.

If you want to buy solar street lights, the first question you should ask yourself is how bright do you want the solar street lights to be? This is important because high-brightness lights may need to be more energy efficient. The brightness of a light is measured in Lux, a unit of measurement used for light intensity. In simple terms, the brightness of any solar street light is determined by its lux output. The lux output varies from model to model, so you must be careful while purchasing solar street lights. If you know the lux output of different solar street lights, it would be easier for you to choose the right brightness.

Why Lux Level Make Sense than Lumen

A lumen is a measure of light output from an individual light source. The lumen measurement is calculated by multiplying the light source’s wattage by the light source’s lumens per watt rating. Lux is the SI unit of illumination. Illumination is the amount of light on a surface. This can be measured in foot candles or the brightness of light after it travels a certain distance. Since the Lumen rating is used to measure the brightness of indoor lights (like bulbs), it is the wrong way to measure the brightness of outdoor lights. The Lux level is the correct way to measure the brightness of solar street lights because the levels are calculated in meters. Now, when you have a solar street light bulb that produces 1000 lumens, it would be a different brightness if it was placed 10 meters away. Therefore, altering the place of the bulb would change the brightness at different Lux levels. Lumen measures how much light a bulb produces; Lux measures how far the light travels.

Different Road lighting Lux Level Standard

Lux standard is calculated by taking account of the width of the road, the height of the light poles and the span or spacing of the poles. Below is a brief overview of the different Lux standards depending on the type of road.

  • Walkways exclusively for pedestrians

For walkways exclusive to pedestrians, the lux standard should be an illuminance of 5 for a luminous intensity of 0.5 per meter and a uniformity of 0.2. This means the solar street light should have a lux measurement of 5 per o.5 feet. This is not too bright as these lights are designed for walkways and pedestrian use.

  • Residential traffic areas for slowly moving vehicles (</ 10 Km/h)

These lights should have a luminous intensity of 10 per 1 foot and a uniformity of 0.2. These lights are designed for use in the home and estate driveways. These are areas where vehicles move at less than 10 kilometers per hour.

  • Regular vehicle traffic (< 40 km/h)

These lights have a luminous intensity of 15-20 per 1.5 to 2 feet. They are lights designed to be installed in intersections or highways with a speed limit of less than 40 km per hour. These lights are brighter than the previous ones, but they are not too bright.

  • Main urban streets

These lights have a luminous intensity of 20 per 2.0 feet. These are lights designed to be used in urban streets like towns and cities. They provide lights for better visibility at night and security.

  • Urban roads

These street lights have a luminous intensity of 2 to 5 per 2 to 0.5 feet depending on the city and the road. These lights are designed for use in highways that pass through major towns and cities. They provide light for truckers and night drivers for better visibility at night.

  • Rural Path and roads

These are street lights meant for use in rural areas without towns or cities. These lights are brighter than other lights because they are the only source of light on the road. They have a luminous intensity of 2 to 5 per 0.2 to 0.5 meters.

  • Pedestrian passages, vehicle turning, loading and unloading points

These are the brightest of all the streets. They have a luminous intensity of 50 per 2 to 5 feet. These lights are used to light pedestrian passages for maximum security and visibility. They are also used for vehicle turning points, loading and unloading points. They offer the biggest amount of light for clear visibility at night.

If Solar Street light can meet the Lux Level Standard

If you want to install solar street lights, you will be required to install a solar luminaire designed to provide a minimum of 5 Lux on the ground surface. On average, a standard solar luminaire can produce around 4-5 Lux. Since solar luminaires are highly dependent on weather conditions, the brightness level may fluctuate slightly. However, you can purchase a street light with an integrated lighting control system (LDC) that detects the amount of light falling on the surface and automatically regulates the brightness level accordingly. So, now you know that the standard brightness is not just measured in Lumen but also in Lux. Therefore, before you purchase a solar street light, you should check the Lux rating of the luminaire to ensure that it is designed to provide sufficient brightness.

The first-generation solar streetlights were built with a Lux rating of 2 Lux. With the advancement of solar street light technology, the manufacturers are now producing lights with a Lux rating of about 5 to 50 Lux. That is enough for roads and streets because the standard street light standards are between 10 and 50 Lux. Modern street lights are designed to meet the Lux standards.

Conclusion

Solar street lights are a great way to add security to the streets, save on electricity bills and be eco-friendly. They are designed to produce a certain amount of light, so make sure you choose one that is powerful enough to light your walkway. To ensure accurate information, it is important to have a clear idea about the basics of solar street lights. It will help you know what to look for in a solar street light and how to decide which one is the best fit for your needs. If you want to add solar street lights to your property, you can use them to illuminate your walkways, gardens, driveways, and more. Solar lights are a great choice for any outdoor space because they are eco-friendly and cost-effective.

What is the best solar light battery

In recent years, due to the advantages of green energy, easy installation, and wide application, which can be installed in remote areas without connecting power grid, solar street lights are waiting for more and more installation and use. How to choose the right solar light battery for your project? LUXMAN summarizes many years of experience and makes the following analysis for you:

GEL battery

suitable for split solar street lights. The earlier split solar street lights are mainly composed of solar panels + GEL batteries + LED lamps. Among them, the solar panel needs to be equipped with a fixed bracket, and the GEL battery needs to be packed in the battery box and buried underground or hung on a light pole. The configured LED lamps generally require a certain length of wiring. It is inconvenient to install, and the product cost and labor cost are high.

solar street light battery

Lithium battery

At present, more split solar street lights use lithium battery box technology, that is, pack a lithium battery pack and controller into a box, usually placed on the back of the solar panel, and some are placed on the bottom of the LED lamp, using an intelligent control system.

solar light battery

Lithium battery pack, there are currently three commonly used lithium batteries of 18650, 26650, and 32650. Relatively speaking, 18650 is usually a ternary lithium battery, no matter the service life and cost performance are not high. Currently, the commonly used LiFePO4 battery specifications are 26650 and 32650. 26650 means diameter D=26mm, length L=65mm; 32650 means diameter D=32mm, length L=65mm. Due to cell size limitations, the battery capacity of the 26650 is not as high as that of the 32650, and the number of batteries using the 32650 to achieve the same configuration is less than that of the 26650.

For example, an 80W integrated solar street light needs a 12.8V 72AH LIFEPO4 battery. The 26650 cell capacity is 4000mah, and the 32650 cell capacity is 6000mah. If 26650 is used for 12.8V 72AH battery pack, 4S18P 72pcs cells are needed, and 32650 is 4S12P 48pcs cells. With the same configuration, the number of batteries using 32650 will be 24pcs less than that of 26650. In terms of price, the current price of 26650 battery 1AH is about RMB 20.00, and the price of 32650 battery 1AH is about RMB 14.00. In this case, if a 26650 battery is used, the battery composition costs 72*20=RMB1440.00, and the cost of using a 32650 battery 72*14=RMB1008.00, the cost gap is obvious. Therefore, the 32650 is cost-effective.

In summary, the battery of solar street lights must first be configured according to the technical requirements of the project, but the cost of the product must also be considered.

The use of LiFePO4 large-capacity batteries is a trend. The cost of solar street lights will be lower and lower, but the quality depends on the factory’s production technology and the ability to control raw materials.

For products with the same appearance, the lower the price, the more you need to be cautious, because regular manufacturers use high-quality raw materials, and the price of high-quality raw materials will not be too cheap. LUXMAN solar street lights use high-quality raw materials, and our quality has been affirmed by customers in the past few years.

solar light for garden

How can we use solar light for garden?

The popularity of solar light is quickly increasing as more and more house owners seek environmentally friendly and cost-effective ways to illuminate their gardens. Solar lights are an excellent choice for garden lighting as they are affordable, easy to install, and only require sunlight to perform. Since the solar light system does not require wiring, it can provide light to those areas of garden or lawn which are at some distance from the electric sources. Solar light for the garden not only provides lighting but can be considered for security or safety purposes.


Based on the unique nature of solar power as an energy source, there are some guidelines for using the solar street light system successfully and efficiently.
Choice of right placement:

As the system runs on sunlight which is then converted into electric power and stored in a battery pack to be used during nights. When making a choice for location, make sure the solar light has access to the sun. Avoid installing the solar light under shades or places that are covered by shadows during some parts of the day. Also, before installing lights, it is helpful to place a marker where each solar light will be located in order to make sure if all the lights will be properly balanced in your landscaping and there are no areas left without light.

Fixing and Installing the light

Some solar lights come with light arm other are separate. Carefully mount solar light on the light arm by following the installation instructions. If the light component has no light arm, then attach and secure the solar lights at those places which have enough sunlight during the day. It is important that the solar panel on the light component is positioned to receive the required amount of sunlight to work properly.

Illuminating specific area

Solar lights can be used to highlight certain features in gardens such as fountain, tree or plant, seating areas, swimming pools, or statues, etc. Due to the evolution is lighting technology, the light bulbs are replaced with LED technology that is far superior to the dim solar lights which were made previously. Installing these LED lights helps to illuminate those specific areas without generating any waste heat.

Using solar lights is just as a sample as mounting the lights to the wall, fence, post, or other existing garden structure.

Illuminating pathways

Another creative use of solar lights is to mount them along the walkways in the garden. These lights are the perfect choice as they do not require any wiring and can easily be installed alongside the pathways. Many people install solar path lights for safety as well as for aesthetics.

Creative Uses

While mostly the solar lights are used for nighttime safety, they can also add up to the beauty of the garden. Solar lights for gardens come in various sizes and styles to suit the user’s needs.

For instance, there are some fancy solar lights that are used alongside the pool, raised beds, water feature, etc. to bring the place to life at night. One can be creative in installing them in any design he wishes to.

Another option is to use the lights to create a visual form such as a heart, star or butterfly by following a certain order. This will add more beauty to the garden.

Solar garden lights are safe

Solar garden lights mostly require 12 Volts to function, which is a safe voltage. 12 V can be found in electric toys, household batteries, etc. 12 Volts is a much safer choice if one has children in the house who play in the garden and the user wants to avoid the use of conventional lights which requires electric wires.
