Why solar LED lights are better than traditional bulbs


Why solar LED lights are better than traditional bulbs

mobile solar lighting, solar lighting, greenshine

At present, new solar lights generally use LED bulbs as their illumination sources. This is another advantage of solar outdoor lighting in addition to its green and sustainable use of solar energy. Although LED lights are still very young compared to the incandescent lamps, which have more than one-hundred-year history, they have obvious advantages over traditional bulbs. Today we will discuss the advantages of LED lights compared to two kinds of traditional bulbs, including incandescent bulbs and energy-saving bulbs. Additionally, we will discuss the disadvantages of LED lights that have not been perfected.



This is the biggest advantage of LED lights. The power of one incandescent bulb varies from 20W-100W, and the power of one so-called “energy-saving bulb” is between 5W-65W. Energy-saving bulbs are a more advanced type of traditional bulbs, and their power is reduced by half. However, the energy saved by energy-saving bulbs is nothing compared to LED lights—the power of one LED bulbs is only 0.8W-12W. It can be seen that the power ratio of the LED bulb to the traditional bulb can reach 1:7, which means LED lights can significantly save your electric bill. That’s on top of the savings earned from using free solar energy for solar LED lights.

Long Service Life

The lifespan of incandescent bulbs and energy-saving bulbs are around 1000 hours and 8000 hours (measured for working 4 hours per day), compared to about 50,000 hours for LED lights (measured for working 24 hours per day). Besides, since LEDs do not have any glass components, they do not easily break like traditional bulbs, which means they have longer service life.


Both incandescent bulbs and energy-saving bulbs produce IR (infrared) and UV (ultraviolet) radiation while working, which may affect human health and the environment in some cases. LED bulbs are safer and more environmentally friendly because they do not have this radiation.

Solar LED Light

Based on the above advantages, solar LED lights are even more advantageous. Solar electric lighting systems do in fact connect to a truly “infinite” power source – the sun. They can be charged during the daytime and used at night, and there is no need for complex and expensive pipeline laying. Solar LED lights can really save a large portion of electricity and maintenance fee.


Although LED bulbs have many advantages—more than those discussed above, they still have defects that need to be perfected. The first comes from their less than competitive price, but the advantages of energy saving and long service life mentioned above can make up for its high initial cost. In the future, we still need to reduce the manufacturing cost of LED bulbs by improving technology to lower their purchase price.

The second drawback of LEDs is their temperature dependence. The performance of LED lights is highly determined by the ambient temperature of their operating environment. Excessive driving of the LED at high temperatures can cause the LED package to overheat and eventually result in device failure. It is especially important in automotive, medical, and military applications because the equipment must operate over a wide range of temperatures, which requires a low failure rate. However, this defect is not obvious for solar outdoor LED lights.

In conclusion, LEDs for outdoor use, such as solar LED streetlights, are still recommended. Although the initial capital investment will be relatively large, over time LEDs can pay for themselves through energy savings and a long service life.

In fact, one of the most popular alternatives for businesses is to invest in solar parking lot lights. To learn more about this opportunity, here is everything you need to know about commercial solar lighting for parking lots.


What Are They?


Solar parking lot lights are a commercial solar lighting solution for parking lots. These products are typically led parking lot lights and include a solar PV panel, a solar charge controller, and a LED light. To learn more about the basics of solar parking lot light, check out this article on the design basics of the solar light.


What Are Their Benefits?


Solar lights are a great option for parking lot lighting since they are off grid and require no trenching. They take little time to install and won’t damage your parking lot in the process. These lights are compatible with all types of parking lots and provide a green source of energy, which reduces long term energy costs and brands your business as an eco-friendly facility. When compared  to traditional led parking lot lights, solar parking lot lights are the best choice for your business.

How Much Do they Cost?


When deciding on lighting for a parking lot, cost is the first consideration. Although many hold the notion that solar power is more expensive, solar is actually less expensive than its traditional counterparts. In fact, solar lights are about 30% cheaper than their counterparts over a 10 year period, making it the most budget friendly option for your project.


Solar parking lot lights are no different. They still offer the most cost-effective, long term solution to optimize the energy efficiency of your business or commercial property. Depending on your needs, solar powered parking lot lights will use overall less energy than standard lights because of its innovative technology, including a dusk-to-dawn feature that will only turn on the lights according to your time specifications. Most parking lot lights also use LED, since they are more effective than regular lights. LED lights for parking lots are about 80% more efficient than other types of lights, so you will convert the most amount of energy possible.


How to Install These Lights?


There are a few factors to consider when installing a LED parking lot light.


Before you install the lights, you need to figure out what your specifications are. Get the blueprints of your area to determine how large it is and lighting engineers will figure out where to put the lights for maximum lighting. Next, you need to determine your lighting requirements and needs. How much illumination do you need? Do you want dark sky compliant lights? Do you need all night lighting, or just a few hours? If these questions seem daunting, do not worry since the lighting company you use will take you through this process step by step.


Next, you will need to assess the actual lights. To evaluate your commercial solar parking lot lights, our engineers will take into account lighting indicators, lighting levels, and color temperature. These are all determined by the specifications you provided above and will determine the products used and installation process. Other key elements for optimizing parking lot lights include determining the quality and quantity of lights that fit your budget, the lighting uniformity of the lights once installed, and the distribution patterns, which is the density of each light in the parking lot. For example, the footprint on the ground is approximately 2.75 times wider than the mounting height, so make sure to ask your lighting specialist about this detail.


How Will Solar Parking Lot Lighting Work for You?


To make sure solar parking lot lights will be right for you, contact a commercial solar lighting supplier, and they will quote and design your project for no cost. This way, you can ensure that you are ready to take on this endeavor and go green with your parking lot.

Solar Lighting Basics

How Does Solar LIghting Work?

Solar lights at dawn

1 Dawn: 

The voltage from the solar panel raises and gets higher than it was during the night. When a certain voltage threshold is reached the controller will detect this and turn off the light. The battery will then being to charge itself from the discharge that occurred when it was powering the light.

solar lights at night

4 Night time: 

The voltage from the solar panel is lower than the pre-set value. After the controller recognizes this situation, the electricity is drawn from the charged battery and continuously powers the lamp fixture. The light will stay on all night until the sun rises and the cycle is completed.

solar lights power in the morning

2 Day time: 

Throughout the day the solar panels will convert the solar energy from the sun into electricity which will charge the battery. The intelligent solar controller charges the battery throughout the day and controls the current to ensure that the battery is not overcharged.

solar lights at dusk

3 Dusk: 

As the sun sets the photocell that is built into the panel will sense the voltage drop as the panels are no longer taking a charge. The battery has been charged throughout the day and is now ready to discharge and provide electricity for the lamp and turn it on. If there is inclement weather, there are at least three days backup for Greenshine’s system.


How to Size a Solar Lighting System

Sizing is a term used to describe the measurements and specifications of an off-grid solar lighting system, which is a system that is not connected to the main power grid. While this task may seem daunting as there are many details taken into account when sizing an off-grid system,  our expert team of engineers will provide these calculations for you. Here’s a brief outline on sizing a solar lighting system.


Unlike most grid-tied systems, solar powered systems are off-grid and naturally powered, which contributes several extra factors when sizing your system. Because there is not a one size fits all model to outdoor solar lighting, our engineers customize each project to your specifications. For example, we base our calculations on your specific location by longitude and latitude to understand the sun exposure in your area. Additionally, we base all of our estimations on the winter solstice, which is the worst case scenario for lighting projects. This ensures that you will still have light even when the least amount of sun is available in your area. In fact, our engineers have even optimized our lights to produce power in cold and snowy conditions for our Mammoth Lakes project.


There are four major steps to create your lighting system, including calculating the load estimation, solar panel amperage, the backup battery, and the inverter system.


Load Estimation


Load estimation refers to the total consumption of your solar system. When designing your solar lights, experts consider how much energy storage do you actually need in Amps at 12VDC. They figure how much total Watt per hour you need per day and multiply it by 1.3 to account for energy lost in the system.


Solar Panel Amperage


An important factor when designing your solar powered system is to figure out the amount of energy each solar panel produces. To do so, take the total Amps required and divide it by the amount of sun available. Then, add 20% extra as a safety net for days with less sunlight.


Amps Per Panel = (Total Amps/ Sunlight Per Day) X 1.2


Backup Battery


Since not all of us are blessed with bright and sunny skys everyday, a backup battery is essential when powering solar street lights. This battery should have a minimum of five nights of autonomy to ensure adequate lighting, with more nights available in the colder, northern regions.


To calculate your backup battery, simply multiply the total amps by the minimum amount of days required.




A solar inverter, or PV inverter, converts the energy generated by the solar panel into usable energy. Typically, inverters convert a direct current (DC) of the solar panel into an alternating current (AC), which can be fed into a commercial grid.


To make life simpler, our solar street lights do not include an inverter, as they are off the main grid system. Our team of engineers will ensure that you will have usable energy in the upcoming years when sizing a solar lighting system.


That’s It!


Once all these steps are completed, our engineers will continuously work with you to ensure your vision for your project becomes a reality. Greenshine will guide you through this process from start to finish to guarantee the best lighting solution possible.

The combination of a solar system with LED lighting is especially practical in remote areas where LED-based lighting systems can be installed without setting up any external infrastructure in the traditional way.

Solar Power Systems for Street Lighting

Off-grid solar systems are not connected to the utility grid and therefore use zero power. Photovoltaic panels gather energy from the sun during the day and keep the battery bank charged. Batteries store the sun’s energy so that it can be used by solar street lights at night.

Off-grid solar systems are best suited for regions and countries where there is no power grid or where connecting the street lights to the grid can be expensive. These systems should have no other maintenance costs but for battery replacements approximately every seven to ten years.

An on-grid solar system is a system that is connected to the utility power grid. The electric power grid functions as a battery, as well. The system stores energy into the grid and then takes it back during the night.

No maintenance or battery replacements are needed for this system. This type of system uses a utility grid serves as a backup power source.

A hybrid solar system is a combination of the two above-mentioned systems. It uses batteries but can also feed excess energy into the electric power grid. Though these systems enable energy independence, they are more complex to install.

How to Evaluate Your Commercial Solar Parking Lot Lights

Many business or commercial property owners have invested in commercial solar parking lot lights to ensure that their business environment is well-lit and welcoming. As well as ensuring safety and security, a brightly-lit lot enhances customer interaction and trust toward a business.

If you are among these green business owners or you are planning to become one, check out these important lighting characteristics.

Lighting Indicators and Levels

Light level or illuminance is expressed in foot-candles (fc). Foot-candles refer to the amount of light that falls onto a square foot. Most parking lots vary between 0.5 and 5 fc. Both foot-candles and lux measure the amount of light delivered in a surface. One lumen per square meter is one lux.

The human eye cannot see illuminance but it can detect luminance. Keep in mind that brighter isn’t always better. Though you may feel tempted to over-illuminate your parking lot, be sure to remember that just like an under-lit lot, an over-lit parking lot can make it difficult for drivers to see.

Hire experienced engineers specialized in solar outdoor lighting, who will carefully plan out and design your parking lot for maximum safety, cost-effectiveness, and aesthetic appeal.

Lighting Uniformity

The lighting uniformity refers to the evenness of illumination in a space. Uneven illumination creates dark and bright spots, which affects perception and visibility. This makes it harder for the human eye to stay in focus.

With optimal commercial solar parking lot lights design, you can achieve adequate light levels and uniform lighting experience. To ensure proper parking lot configuration, the surrounding landscape and infrastructure should be taken into consideration. With no shadows and dark spots, the customers or visitors who park in your parking lot will feel safe and secure.

Color Temperature

The color rendering index (CRI) of a light source is a measure of the source’s ability to realistically reproduce all colors of the spectrum in comparison with a natural or ideal light source. In other words, CRI describes how a light source makes the color of an object appear to the human eye.

Poor color rendition won’t give observers the chance to spot and distinguish subtle color differences and contrasts on surfaces and objects. LED parking lot lights, however, can provide the most desirable color rendering index. A higher CRI in parking lot fixtures means a more natural and accurate output of light, enabling parkers in your lot to see more clearly.

Lighting Solutions for Rails with Trails

train - solar trail lightsTrails run along many active rail lines to provide transportation, access to transit, and recreational opportunities for thousands of Americans. There is also a growing number of former rail lines being converted into multi-purpose public paths.

Safety should always be the primary concern when developing a rail-with-trail. Illuminating rails is one of the ways to make the trail safe and more convenient to use at night. Let’s look at each player, the benefits/costs of each, and the overall quality of each type of lighting solution.

Types of Lighting

There’s a myriad of factors influencing lighting choices, such as trail location and features, overhead clearance, weather, soil content, etc.

Wired lights. Wired lighting is a costly decision. If well-designed and high quality, wired lighting can be easy to maintain and operate. However, it is expensive to install and complicated to repair.

The wires could be strung overhead or underground. Underground wiring is expensive but durable since it will not be damaged by poor weather conditions. While cheaper, overhead lighting is more vulnerable to weather-able conditions.

Battery powered lights. This option is the cheapest to install and repair but difficult to maintain since the batteries may need to be frequently replaced. If dead batteries go unnoticed, trail users have to face a dark section and their safety is jeopardized. For this reason, battery-powered lights are practical only on high-traffic trails, where a dead battery is likely to be replaced promptly.

Solar trail lights. These lights are powered by the sun so they are the most environmentally conscious solution. When solar trail lights are installed in more sunny regions, they are sure to operate at maximum strength.

This system also has little to no cost of operation, drastically reducing cost. Because there are no wires connecting solar lights, repairs are contained to a single fixture at a time, making repairs easy and time efficient.

LEDs. In comparison to standard incandescent bulbs, LEDs are extremely energy efficient and need very little power to generate light. They do have a higher initial cost but have an exceptional operational lifetime. Therefore, LEDs can provide huge long-term savings.

Reflective striping. Trails with dark spots and limited night use may benefit from the striping, which is the addition to the already existing lights. These white, flat and narrow reflectors can increase the amount of light and are especially useful if a trail is near a lit street.

Placement and Design

To develop a secure and accessible bicycle, pedestrian, and trail system, consult a professional who will plan out a proper design strategy. The implementation will help create a safe environment for trail users and rail operators.

Trail lighting that is well-placed, properly installed, and regularly maintained can enhance visibility, improve overall trail access, and convenience for users, supplying a  sense of security while using the trail from dusk till dawn.

Unlike highway lighting, trail lighting should be done on a small scale and only when necessary. Fixtures should shed light only on the path below. Preferably, there should be no glare or loss of light. In some cases, bollards would cast just enough light.


Wired lighting poses a challenge due to difficulties in tracking and repairing outages. A whole string of lights could go out when initially only one is the problem. With solar lighting, these problems can be avoided. Solar trail lights are practical because of their long lifespan, low cost, and maintenance. They can last for many years of stable operation if they are well cared for.

Rail to Trail Verdict: Solar Trail Lighting

Solar trail lights are an efficient, green and economical solution. They are a sustainable solution for well-lit spaces since they are built to last. Reliable and cost-effective, solar lighting provides energy savings and contributes to the safety of anyone going jogging at night, cycling after dinner or taking an early-morning walk along a rail.

At Greenshine New Energy LLC., we specialize in developing and manufacturing solar street lights, garden light, path light, park lights and lawn lights for outdoor applications. Our solar lighting solutions work on innovative technology to provide communities with top-notch solar trail lights at competitive prices and free of maintenance.
